NAME


aegis file attributes - modify the attributes of a file

SYNOPSIS


aegis -File_ATtributes -File attr-file [ option... ] filename
aegis -File_ATtributes -Edit [ option... ] filename
aegis -File_ATtributes [ option... ] name=value filename
aegis -File_ATtributes -UUID number -File filename
aegis -File_ATtributes -Help

DESCRIPTION


The aegis -File_ATtributes command is used to set, edit or list the attributes of a file.

The output of the -List variant is suitable for use as input at a later time.

See aefattr(5) for a description of the file format.

Attribute names are not case sensitive. File attributes with a name starting with an
upper case letter will appear in ael(1) and aeget(1) listings, while those starting with
a lower case letter will not.

Shorthand
If you are only setting the values of unique attributes, it is possible to do this from
the command line, using the name=value form.

Note that this usage will replace the first attribute with the given name. If there is
more than one attribute of that name, the second and subsequent attributes are unchanged.
If there is no attribute of the given name, it will be appended.

You may set more than one attribute at a time, provided that their names are unique.
Attribute names are not case sensitive.

Known Attribute Names
While many of the anticipated uses of file attributes are to allow projects to attach
their own specialized data to individual files, Aegis also uses some attributes for its
own purposes (and arguably, should always have done so to maximize forwards compatibility
across Aegis upgrades).

content-type
This is taken directly from the MIME definition of Content-Type. It remembers
what sort of file this is. It is anticipated that a diff tool, for example,
could make use of this attribute to provide format-specific file difference
listings. Some change set interchange formats are capable of carrying this
information.

entire-source-hide
boolean. If true, this file is not included by the aedist -entire-source flag.
The aetar and aerevml commands work similarly. Think of it as a "local only"
flag.

foreign-copyright
boolean. If true, this file will not be checked by the aede-policy(1) copyright
validation.

aede-policy-tabs-allowed
boolean. If true, the no-tabs policy of the aede-policy(1) command does not
apply.

aede-policy-line-length
integer. The maximum allowed line length in the line-length policy of the aede-
policy(1) command; infinity if 0.

local-source-hide
boolean. If true, this file is not included by aedist change sets. The aetar
and aerevml commands work similarly. Change sets which contain only thee files
will be omitted from the aedist -inventory output. Think of it as a "local only"
flag.

aeipass-options:assign-file-uuid
boolean. If false, aeipass will not assign a fresh UUID to this file. This flag
is set by aedist -rec if the action associated with the file is a create and the
file is missing the UUID. This behaviour is needed to prevent the effect of
having different UUIDs assigned to the same file in different repositories.

OPTIONS


The following options are understood:

-BAse_RElative
This option may be used to cause relative filenames to be considered relative to
the base of the source tree. See aeuconf(5) for the corresponding user
preference.

-CUrrent_RElative
This option may be used to cause relative filenames to be considered relative to
the current directory. This is usually the default. See aeuconf(5) for the
corresponding user preference.

-Change number
This option may be used to specify a particular change within a project. See
aegis(1) for a complete description of this option.

-Help
This option may be used to obtain more information about how to use the aegis
program.

-List
This option may be used to obtain a list of suitable subjects for this command.
The list may be more general than expected.

-Project name
This option may be used to select the project of interest. When no -Project
option is specified, the AEGIS_PROJECT environment variable is consulted. If
that does not exist, the user's $HOME/.aegisrc file is examined for a default
project field (see aeuconf(5) for more information). If that does not exist,
when the user is only working on changes within a single project, the project
name defaults to that project. Otherwise, it is an error.

-TERse
This option may be used to cause listings to produce the bare minimum of
information. It is usually useful for shell scripts.
-Universal_Unique_IDentifier number This option may be used to set the UUID of a
file.

-Verbose
This option may be used to cause aegis to produce more output. By default aegis
only produces output on errors. When used with the -List option this option
causes column headings to be added.

-Wait This option may be used to require Aegis commands to wait for access locks, if
they cannot be obtained immediately. Defaults to the user's lock_wait_preference
if not specified, see aeuconf(5) for more information.

-No_Wait
This option may be used to require Aegis commands to emit a fatal error if access
locks cannot be obtained immediately. Defaults to the user's
lock_wait_preference if not specified, see aeuconf(5) for more information.

See also aegis(1) for options common to all aegis commands.

All options may be abbreviated; the abbreviation is documented as the upper case letters,
all lower case letters and underscores (_) are optional. You must use consecutive
sequences of optional letters.

All options are case insensitive, you may type them in upper case or lower case or a
combination of both, case is not important.

For example: the arguments "-project, "-PROJ" and "-p" are all interpreted to mean the
-Project option. The argument "-prj" will not be understood, because consecutive
optional characters were not supplied.

Options and other command line arguments may be mixed arbitrarily on the command line,
after the function selectors.

The GNU long option names are understood. Since all option names for aegis are long,
this means ignoring the extra leading '-'. The "--option=value" convention is also
understood.

RECOMMENDED ALIAS


The recommended alias for this command is
csh% alias aefa 'aegis -fat \!* -v'
sh$ aefa(){aegis -fat "$@" -v}

ERRORS


It is an error if the current user is not an administrator of the specified project.
It is an error if the current user is not the developer of the specified change.
It is an error if the file is not included in the specified change.

EXIT STATUS


The aegis command will exit with a status of 1 on any error. The aegis command will only
exit with a status of 0 if there are no errors.

ENVIRONMENT VARIABLES


See aegis(1) for a list of environment variables which may affect this command. See
aepconf(5) for the project configuration file's project_specific field for how to set
environment variables for all commands executed by Aegis.
