Ubuntu Manpage: aegis file attributes - modify the attributes of a file

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.
