PROGRAM:

NAME


resize - set environment and terminal settings to current xterm window size

SYNOPSIS


resize [ -v | -u | -c ] [ -s [ row col ] ]

DESCRIPTION


Resize prints a shell command for setting the appropriate environment variables to
indicate the current size of xterm window from which the command is run.

Resize determines the command through several steps:

· first, it finds the name of the user's shell program. It uses the SHELL variable if
set, otherwise it uses the user's data from /etc/passwd.

· then it decides whether to use Bourne shell syntax or C-Shell syntax. It uses a
built-in table of known shells, which can be overridden by the -u and -c options.

· then resize asks the operating system for the terminal settings. This is the same
information which can be manipulated using stty.

· then resize asks the terminal for its size in characters. Depending on whether the
"-s option is given, resize uses a different escape sequence to ask for this
information.

· at this point, resize attempts to update the terminal settings to reflect the terminal
window's size in pixels:

· if the -s option is used, resize then asks the terminal for its size in pixels.

· otherwise, resize asks the operating system for the information and updates that
after ensuring that the window's dimensions are a multiple of the character height
and width.

· in either case, the updated terminal settings are done using a different system
call than used for stty.

· then resize updates the terminal settings to reflect any altered values such as its
size in rows or columns. This affects the values shown by stty.

· finally, resize writes the shell command for setting the environment variables to the
standard output.

EXAMPLES


For resize's output to take effect, resize must either be evaluated as part of the command
line (usually done with a shell alias or function) or else redirected to a file which can
then be read in. From the C shell (usually known as /bin/csh), the following alias could
be defined in the user's .cshrc:

% alias rs 'set noglob; eval `resize`'

After resizing the window, the user would type:

% rs

Users of versions of the Bourne shell (usually known as /bin/sh) that don't have command
functions will need to send the output to a temporary file and then read it back in with
the “.” command:

$ resize > /tmp/out
$ . /tmp/out

OPTIONS


The following options may be used with resize:

-c This option indicates that C shell commands should be generated even if the user's
current shell is not /bin/csh.

-s [rows columns]
This option indicates that Sun console escape sequences will be used instead of
the VT100-style xterm escape codes. If rows and columns are given, resize will
ask the xterm to resize itself using those values.

Both of the escape sequences used for this option (first to obtain the window size
and second to modify it) are subject to xterm's allowWindowOps resource setting.
The window manager may also choose to disallow the change.

The VT100-style escape sequence used to determine the screen size always works for
VT100-compatible terminals. VT100s have no corresponding way to modify the
screensize.

-u This option indicates that Bourne shell commands should be generated even if the
user's current shell is not /bin/sh.

-v This causes resize to print a version number to the standard output, and then
exit.

Note that the Sun console escape sequences are recognized by XFree86 xterm and by dtterm.
The resize program may be installed as sunsize, which causes makes it assume the -s
option.

The rows and columns arguments must appear last; though they are normally associated with
the -s option, they are parsed separately.
