NAME

pterm ‐ yet another X terminal emulator

SYNOPSIS

pterm [ options ]

DESCRIPTION

pterm is a terminal emulator for X. It is based on a port of the terminal emulation engine
in the Windows SSH client PuTTY.

OPTIONS

The command-line options supported by pterm are:

-e command [ arguments ]
Specify a command to be executed in the new terminal. Everything on the command
line after this option will be passed straight to the execvp system call; so if you
need the command to redirect its input or output, you will have to use sh:

pterm -e sh -c 'mycommand < inputfile'

--display display-name
Specify the X display on which to open pterm. (Note this option has a double minus
sign, even though none of the others do. This is because this option is supplied
automatically by GTK. Sorry.)

-name name
Specify the name under which pterm looks up X resources. Normally it will look them
up as (for example) pterm.Font. If you specify `-name xyz', it will look them up as
xyz.Font instead. This allows you to set up several different sets of defaults and
choose between them.

-fn font-name
Specify the font to use for normal text displayed in the terminal.

-fb font-name
Specify the font to use for bold text displayed in the terminal. If the
BoldAsColour resource is set to 1 (the default), bold text will be displayed in
different colours instead of a different font, so this option will be ignored. If
BoldAsColour is set to 0 or 2 and you do not specify a bold font, pterm will
overprint the normal font to make it look bolder.

-fw font-name
Specify the font to use for double-width characters (typically Chinese, Japanese
and Korean text) displayed in the terminal.

-fwb font-name
Specify the font to use for bold double-width characters (typically Chinese,
Japanese and Korean text). Like -fb, this will be ignored unless the BoldAsColour
resource is set to 0 or 2.

-geometry geometry
Specify the size of the terminal, in rows and columns of text. See X(7) for more
information on the syntax of geometry specifications.

-sl lines
Specify the number of lines of scrollback to save off the top of the terminal.

-fg colour
Specify the foreground colour to use for normal text.

-bg colour
Specify the background colour to use for normal text.

-bfg colour
Specify the foreground colour to use for bold text, if the BoldAsColour resource is
set to 1 (the default) or 2.

-bbg colour
Specify the foreground colour to use for bold reverse-video text, if the
BoldAsColour resource is set to 1 (the default) or 2. (This colour is best thought
of as the bold version of the background colour; so it only appears when text is
displayed in the background colour.)

-cfg colour
Specify the foreground colour to use for text covered by the cursor.

-cbg colour
Specify the background colour to use for text covered by the cursor. In other
words, this is the main colour of the cursor.

-title title
Specify the initial title of the terminal window. (This can be changed under
control of the server.)

-ut- or +ut
Tells pterm not to record your login in the utmp, wtmp and lastlog system log
files; so you will not show up on finger or who listings, for example.

-ut Tells pterm to record your login in utmp, wtmp and lastlog: this is the opposite of
-ut-. This is the default option: you will probably only need to specify it
explicitly if you have changed the default using the StampUtmp resource.

-ls- or +ls
Tells pterm not to execute your shell as a login shell.

-ls Tells pterm to execute your shell as a login shell: this is the opposite of -ls-.
This is the default option: you will probably only need to specify it explicitly if
you have changed the default using the LoginShell resource.

-sb- or +sb
Tells pterm not to display a scroll bar.

-sb Tells pterm to display a scroll bar: this is the opposite of -sb-. This is the
default option: you will probably only need to specify it explicitly if you have
changed the default using the ScrollBar resource.

-log logfile, -sessionlog logfile
This option makes pterm log all the terminal output to a file as well as displaying
it in the terminal.

-cs charset
This option specifies the character set in which pterm should assume the session is
operating. This character set will be used to interpret all the data received from
the session, and all input you type or paste into pterm will be converted into this
character set before being sent to the session.

Any character set name which is valid in a MIME header (and supported by pterm)
should be valid here (examples are `ISO-8859-1', `windows-1252' or `UTF-8'). Also,
any character encoding which is valid in an X logical font description should be
valid (`ibm-cp437', for example).

pterm's default behaviour is to use the same character encoding as its primary
font. If you supply a Unicode (iso10646-1) font, it will default to the UTF-8
character set.

Character set names are case-insensitive.

-nethack
Tells pterm to enable NetHack keypad mode, in which the numeric keypad generates
the NetHack hjklyubn direction keys. This enables you to play NetHack with the
numeric keypad without having to use the NetHack number_pad option (which requires
you to press `n' before any repeat count). So you can move with the numeric keypad,
and enter repeat counts with the normal number keys.

-xrm resource-string
This option specifies an X resource string. Useful for setting resources which do
not have their own command-line options. For example:

pterm -xrm 'ScrollbarOnLeft: 1'

-help, --help
Display a message summarizing the available options.

-pgpfp Display the fingerprints of the PuTTY PGP Master Keys, to aid in verifying new
files released by the PuTTY team.

X RESOURCES

pterm can be more completely configured by means of X resources. All of these resources
are of the form pterm.FOO for some FOO; you can make pterm look them up under another
name, such as xyz.FOO, by specifying the command-line option `-name xyz'.

pterm.CloseOnExit
This option should be set to 0, 1 or 2; the default is 2. It controls what pterm
does when the process running inside it terminates. When set to 2 (the default),
pterm will close its window as soon as the process inside it terminates. When set
to 0, pterm will print the process's exit status, and the window will remain
present until a key is pressed (allowing you to inspect the scrollback, and copy
and paste text out of it).

When this setting is set to 1, pterm will close immediately if the process exits
cleanly (with an exit status of zero), but the window will stay around if the
process exits with a non-zero code or on a signal. This enables you to see what
went wrong if the process suffers an error, but not to have to bother closing the
window in normal circumstances.

pterm.WarnOnClose
This option should be set to either 0 or 1; the default is 1. When set to 1, pterm
will ask for confirmation before closing its window when you press the close
button.

pterm.TerminalType
This controls the value set in the TERM environment variable inside the new
terminal. The default is `xterm'.

pterm.BackspaceIsDelete
This option should be set to either 0 or 1; the default is 1. When set to 0, the
ordinary Backspace key generates the Backspace character (^H); when set to 1, it
generates the Delete character (^?). Whichever one you set, the terminal device
inside pterm will be set up to expect it.

pterm.RXVTHomeEnd
This option should be set to either 0 or 1; the default is 0. When it is set to 1,
the Home and End keys generate the control sequences they would generate in the
rxvt terminal emulator, instead of the more usual ones generated by other
emulators.

pterm.LinuxFunctionKeys
This option can be set to any number between 0 and 5 inclusive; the default is 0.
The modes vary the control sequences sent by the function keys; for more complete
documentation, it is probably simplest to try each option in `pterm -e cat', and
press the keys to see what they generate.

pterm.NoApplicationKeys
This option should be set to either 0 or 1; the default is 0. When set to 1, it
stops the server from ever switching the numeric keypad into application mode
(where the keys send function-key-like sequences instead of numbers or arrow keys).
You probably only need this if some application is making a nuisance of itself.

pterm.NoApplicationCursors
This option should be set to either 0 or 1; the default is 0. When set to 1, it
stops the server from ever switching the cursor keys into application mode (where
the keys send slightly different sequences). You probably only need this if some
application is making a nuisance of itself.

pterm.NoMouseReporting
This option should be set to either 0 or 1; the default is 0. When set to 1, it
stops the server from ever enabling mouse reporting mode (where mouse clicks are
sent to the application instead of controlling cut and paste).

pterm.NoRemoteResize
This option should be set to either 0 or 1; the default is 0. When set to 1, it
stops the server from being able to remotely control the size of the pterm window.

pterm.NoAltScreen
This option should be set to either 0 or 1; the default is 0. When set to 1, it
stops the server from using the `alternate screen' terminal feature, which lets
full-screen applications leave the screen exactly the way they found it.

pterm.NoRemoteWinTitle
This option should be set to either 0 or 1; the default is 0. When set to 1, it
stops the server from remotely controlling the title of the pterm window.

pterm.NoRemoteQTitle
This option should be set to either 0 or 1; the default is 1. When set to 1, it
stops the server from remotely requesting the title of the pterm window.

This feature is a POTENTIAL SECURITY HAZARD. If a malicious application can write
data to your terminal (for example, if you merely cat a file owned by someone else
on the server machine), it can change your window title (unless you have disabled
this using the NoRemoteWinTitle resource) and then use this service to have the new
window title sent back to the server as if typed at the keyboard. This allows an
attacker to fake keypresses and potentially cause your server-side applications to
do things you didn't want. Therefore this feature is disabled by default, and we
recommend you do not turn it on unless you really know what you are doing.

pterm.NoDBackspace
This option should be set to either 0 or 1; the default is 0. When set to 1, it
disables the normal action of the Delete (^?) character when sent from the server
to the terminal, which is to move the cursor left by one space and erase the
character now under it.

pterm.ApplicationCursorKeys
This option should be set to either 0 or 1; the default is 0. When set to 1, the
default initial state of the cursor keys are application mode (where the keys send
function-key-like sequences instead of numbers or arrow keys). When set to 0, the
default state is the normal one.

pterm.ApplicationKeypad
This option should be set to either 0 or 1; the default is 0. When set to 1, the
default initial state of the numeric keypad is application mode (where the keys
send function-key-like sequences instead of numbers or arrow keys). When set to 0,
the default state is the normal one.

pterm.NetHackKeypad
This option should be set to either 0 or 1; the default is 0. When set to 1, the
numeric keypad operates in NetHack mode. This is equivalent to the -nethack
command-line option.

pterm.Answerback
This option controls the string which the terminal sends in response to receiving
the ^E character (`tell me about yourself'). By default this string is `PuTTY'.

pterm.HideMousePtr
This option should be set to either 0 or 1; the default is 0. When it is set to 1,
the mouse pointer will disappear if it is over the pterm window and you press a
key. It will reappear as soon as you move it.

pterm.WindowBorder
This option controls the number of pixels of space between the text in the pterm
window and the window frame. The default is 1. You can increase this value, but
decreasing it to 0 is not recommended because it can cause the window manager's
size hints to work incorrectly.

pterm.CurType
This option should be set to either 0, 1 or 2; the default is 0. When set to 0, the
text cursor displayed in the window is a rectangular block. When set to 1, the
cursor is an underline; when set to 2, it is a vertical line.

pterm.BlinkCur
This option should be set to either 0 or 1; the default is 0. When it is set to 1,
the text cursor will blink when the window is active.

pterm.Beep
This option should be set to either 0 or 2 (yes, 2); the default is 0. When it is
set to 2, pterm will respond to a bell character (^G) by flashing the window
instead of beeping.

pterm.BellOverload
This option should be set to either 0 or 1; the default is 0. When it is set to 1,
pterm will watch out for large numbers of bells arriving in a short time and will
temporarily disable the bell until they stop. The idea is that if you cat a binary
file, the frantic beeping will mostly be silenced by this feature and will not
drive you crazy.

The bell overload mode is activated by receiving N bells in time T; after a further
time S without any bells, overload mode will turn itself off again.

Bell overload mode is always deactivated by any keypress in the terminal. This
means it can respond to large unexpected streams of data, but does not interfere
with ordinary command-line activities that generate beeps (such as filename
completion).

pterm.BellOverloadN
This option counts the number of bell characters which will activate bell overload
if they are received within a length of time T. The default is 5.

pterm.BellOverloadT
This option specifies the time period in which receiving N or more bells will
activate bell overload mode. It is measured in microseconds, so (for example) set
it to 1000000 for one second. The default is 2000000 (two seconds).

pterm.BellOverloadS
This option specifies the time period of silence required to turn off bell overload
mode. It is measured in microseconds, so (for example) set it to 1000000 for one
second. The default is 5000000 (five seconds of silence).

pterm.ScrollbackLines
This option specifies how many lines of scrollback to save above the visible
terminal screen. The default is 200. This resource is equivalent to the -sl
command-line option.

pterm.DECOriginMode
This option should be set to either 0 or 1; the default is 0. It specifies the
default state of DEC Origin Mode. (If you don't know what that means, you probably
don't need to mess with it.)

pterm.AutoWrapMode
This option should be set to either 0 or 1; the default is 1. It specifies the
default state of auto wrap mode. When set to 1, very long lines will wrap over to
the next line on the terminal; when set to 0, long lines will be squashed against
the right-hand edge of the screen.

pterm.LFImpliesCR
This option should be set to either 0 or 1; the default is 0. When set to 1, the
terminal will return the cursor to the left side of the screen when it receives a
line feed character.

pterm.WinTitle
This resource is the same as the -T command-line option: it controls the initial
title of the window. The default is `pterm'.

pterm.TermWidth
This resource is the same as the width part of the -geometry command-line option:
it controls the number of columns of text in the window. The default is 80.

pterm.TermHeight
This resource is the same as the width part of the -geometry command-line option:
it controls the number of columns of text in the window. The defaults is 24.

pterm.Font
This resource is the same as the -fn command-line option: it controls the font used
to display normal text. The default is `fixed'.

pterm.BoldFont
This resource is the same as the -fb command-line option: it controls the font used
to display bold text when BoldAsColour is set to 0 or 2. The default is unset (the
font will be bolded by printing it twice at a one-pixel offset).

pterm.WideFont
This resource is the same as the -fw command-line option: it controls the font used
to display double-width characters. The default is unset (double-width characters
cannot be displayed).

pterm.WideBoldFont
This resource is the same as the -fwb command-line option: it controls the font
used to display double-width characters in bold, when BoldAsColour is set to 0 or
2. The default is unset (double-width characters are displayed in bold by printing
them twice at a one-pixel offset).

pterm.ShadowBoldOffset
This resource can be set to an integer; the default is ‐1. It specifies the offset
at which text is overprinted when using `shadow bold' mode. The default (1) means
that the text will be printed in the normal place, and also one character to the
right; this seems to work well for most X bitmap fonts, which have a blank line of
pixels down the right-hand side. For some fonts, you may need to set this to ‐1, so
that the text is overprinted one pixel to the left; for really large fonts, you may
want to set it higher than 1 (in one direction or the other).

pterm.BoldAsColour
This option should be set to either 0, 1, or 2; the default is 1. It specifies how
bold text should be displayed. When set to 1, bold text is shown by displaying it
in a brighter colour; when set to 0, bold text is shown by displaying it in a
heavier font; when set to 2, both effects happen at once (a heavy font and a
brighter colour).

pterm.Colour0, pterm.Colour1, ..., pterm.Colour21
These options control the various colours used to display text in the pterm window.
Each one should be specified as a triple of decimal numbers giving red, green and
blue values: so that black is `0,0,0', white is `255,255,255', red is `255,0,0' and
so on.

Colours 0 and 1 specify the foreground colour and its bold equivalent (the -fg and
-bfg command-line options). Colours 2 and 3 specify the background colour and its
bold equivalent (the -bg and -bbg command-line options). Colours 4 and 5 specify
the text and block colours used for the cursor (the -cfg and -cbg command-line
options). Each even number from 6 to 20 inclusive specifies the colour to be used
for one of the ANSI primary colour specifications (black, red, green, yellow, blue,
magenta, cyan, white, in that order); the odd numbers from 7 to 21 inclusive
specify the bold version of each colour, in the same order. The defaults are:

pterm.Colour0: 187,187,187
pterm.Colour1: 255,255,255
pterm.Colour2: 0,0,0
pterm.Colour3: 85,85,85
pterm.Colour4: 0,0,0
pterm.Colour5: 0,255,0
pterm.Colour6: 0,0,0
pterm.Colour7: 85,85,85
pterm.Colour8: 187,0,0
pterm.Colour9: 255,85,85
pterm.Colour10: 0,187,0
pterm.Colour11: 85,255,85
pterm.Colour12: 187,187,0
pterm.Colour13: 255,255,85
pterm.Colour14: 0,0,187
pterm.Colour15: 85,85,255
pterm.Colour16: 187,0,187
pterm.Colour17: 255,85,255
pterm.Colour18: 0,187,187
pterm.Colour19: 85,255,255
pterm.Colour20: 187,187,187
pterm.Colour21: 255,255,255

pterm.RectSelect
This option should be set to either 0 or 1; the default is 0. When set to 0,
dragging the mouse over several lines selects to the end of each line and from the
beginning of the next; when set to 1, dragging the mouse over several lines selects
a rectangular region. In each case, holding down Alt while dragging gives the other
behaviour.

pterm.MouseOverride
This option should be set to either 0 or 1; the default is 1. When set to 1, if the
application requests mouse tracking (so that mouse clicks are sent to it instead of
doing selection), holding down Shift will revert the mouse to normal selection.
When set to 0, mouse tracking completely disables selection.

pterm.Printer
This option is unset by default. If you set it, then server-controlled printing is
enabled: the server can send control sequences to request data to be sent to a
printer. That data will be piped into the command you specify here; so you might
want to set it to `lpr', for example, or `lpr -Pmyprinter'.

pterm.ScrollBar
This option should be set to either 0 or 1; the default is 1. When set to 0, the
scrollbar is hidden (although Shift-PageUp and Shift-PageDown still work). This is
the same as the -sb command-line option.

pterm.ScrollbarOnLeft
This option should be set to either 0 or 1; the default is 0. When set to 1, the
scrollbar will be displayed on the left of the terminal instead of on the right.

pterm.ScrollOnKey
This option should be set to either 0 or 1; the default is 0. When set to 1, any
keypress causes the position of the scrollback to be reset to the very bottom.

pterm.ScrollOnDisp
This option should be set to either 0 or 1; the default is 1. When set to 1, any
activity in the display causes the position of the scrollback to be reset to the
very bottom.

pterm.LineCodePage
This option specifies the character set to be used for the session. This is the
same as the -cs command-line option.

pterm.NoRemoteCharset
This option disables the terminal's ability to change its character set when it
receives escape sequences telling it to. You might need to do this to interoperate
with programs which incorrectly change the character set to something they think is
sensible.

pterm.BCE
This option should be set to either 0 or 1; the default is 1. When set to 1, the
various control sequences that erase parts of the terminal display will erase in
whatever the current background colour is; when set to 0, they will erase in black
always.

pterm.BlinkText
This option should be set to either 0 or 1; the default is 0. When set to 1, text
specified as blinking by the server will actually blink on and off; when set to 0,
pterm will use the less distracting approach of making the text's background colour
bold.

pterm.StampUtmp
This option should be set to either 0 or 1; the default is 1. When set to 1, pterm
will log the login in the various system log files. This resource is equivalent to
the -ut command-line option.

pterm.LoginShell
This option should be set to either 0 or 1; the default is 1. When set to 1, pterm
will execute your shell as a login shell. This resource is equivalent to the -ls
command-line option.
