All function selectors are case insensitive. Function selectors may be abbreviated; the abbreviation is the upper case letters. Function selectors must appear as the first command line argument.

Notification

Many aegis commands are capable of notification that they have been run. The individual commands document those specific to them. For documentation on the various configurable notifications, see aepconf(5) and aepattr(5) for more information.

OPTIONS

The following options are available to all functions. These options may appear anywhere on the command line following the function selectors.

-LIBrary abspath: This option may be used to specify a directory to be searched for global state files and user state files. (See aegstate(5) and aeustate(5) for more information.) Several library options may be present on the command line, and are search in the order given. Appended to this explicit search path are the directories specified by the AEGIS_PATH environment variable (colon separated), and finally, /usr/local/lib/aegis is always searched. All paths specified, either on the command line or in the AEGIS_PATH environment variable, must be absolute.
-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.

The following options are available to most functions. These options may appear anywhere on the command line following the function selectors.

-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.
-Change number: This option may be used to specify a particular change within a project. When no -Change option is specified, the AEGIS_CHANGE environment variable is consulted. If that does not exist, the user's $HOME/.aegisrc file is examined for a default change field (see aeuconf(5) for more information). If that does not exist, when the user is only working on one change within a project, that is the default change number. Otherwise, it is an error.
-Change project.Cnumber: As a shortcut, it is possible to combine the -Project and -Change options into a single option.
-Change branch.Cnumber: Several functions accept a -BRanch option; it is possible to combine the -BRanch and -Change options in a single option. (This intentinally has the same form as the ${version} substitution output for incomplete changes.)
-Change branch.Dnumber: Several functions accept both the -BRanch and -Delta options (or -BRanch and -Change‐From‐Delta options); it is possible to combine them in a single option. (This intentinally has the same form as the ${version} substitution output for completed changes.)
-Change project.Dnumber: It is possible to combine the -Project and -Change‐From‐Delta options as a single option.
-Change UUID: Each completed change is assigned a globallay unique identifier (UUID). You can specify a change by its 36‐character UUID, or any unambiguous leading predix of the UUID (it must be at least 4 characters, and not look like a number).

Listings

The following options are available to all listings. These options may appear anywhere on the command line following the function selectors.

-PAGer: The output of listings and help is piped through the pager command given in the PAGER environment variable (or more if not set). This is the default if the command is in the foreground, and the output is a TTY. This option may be used to override any preference specified in the aeuconf(5) file.
-No_PAGer: This option may be used to ensure that the output of listings and help is not piped through a pager command. This is the default if the command is in the background, or if the output is not a TTY. This option may be used to override any preference specified in the aeuconf(5) file.
-Page_Length number: This option may be used to set the page length of listings. The default, in order of preference, is obtained from the system, from the LINES environment variable, or set to 24 lines.
-Page_Width number: This option may be used to set the page width of listings and error messages. The default, in order of preference, is obtained from the system, from the COLS environment variable, or set to 79 characters.
-TERse: This option may be used to cause listings to produce the bare minimum of information. It is usually useful for shell scripts.
-UNFormatted: This option may be used with most listings to specify that the column formatting is not to be performed. This is useful for shell scripts.
-Page-Header: This option requests that page headings be present in listings and reports. This is the default.
-No-Page-Header: This option requests that page headings be omitted from listings and reports.

Abbreviations

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.

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

The aegis command understands the following environment variables:

AEGIS_PATH: A colon‐separated list of library directories. See the -LIBrary option for a description how this environment variable is used.
AEGIS_PROJECT: Names a default project. See the -Project option for a description how this environment variable is used.
AEGIS_CHANGE: Specifies a default change. See the -Change option for a description how this environment variable is used.
AEGIS_FLAGS: This environment variable is used to hold aeuconf(5) information, and over‐rides the settings in the users .aegisrc file. This is intended to be used within the tests distributed with aegis, but can also be of use within some shell scripts.
AEGIS_THROTTLE: Specifies the number of seconds to delay execution within commands which set time stamps. This is intended to be used within the tests distributed with aegis, but can also be of use within some shell scripts.
AEGIS_AUTOMOUNT_POINTS

A colon‐separated list of directories which the automounter may use to mount file systems. Use with extreme care, as this distorts Aegis' idea of the shape of the filesystem.

This feature assumes that paths below the automounter's mount directory are echoes of paths without it. E.g. When /home is the trigger, and /tmp_mnt/home is where the on‐demand NFS mount is performed, with /home appearing to processes to be a symlink.

This is the behavior of the Sun automounter. The AMD automounter is capable of being configured in this way, though it is not typical of the examples in the manual. Nor is it typical of the out‐of‐the‐box Linux AMD configuration in many distributions.

COLS: Specifies the page width for errors and listings. See the -Page_Width option for a description how this environment variable is used.
EDITOR: Specifies the program use to edit files when the -Edit or -Edit_BackGround options are used. (See also the VISUAL environment variable.) Defaults to vi if not set. See the editor_command fields in aeuconf(1) for how to override this specifically for Aegis.
LINES: Specifies the page length for listings. See the -Page_Length option for a description how this environment variable is used.
PAGER: Specifies the program to use to view listings and help. Not used if output is to a file or a pipe. Defaults to more if not set.
VISUAL: Specifies the program use to edit files when the -Edit option is used. (See also the EDITOR environment variable.) Defaults to vi if not set. See the visual_command fields in aeuconf(1) for how to override this specifically for Aegis.
AEGIS_DATADIR: Overrides the datadir as specified at configure invocation. Useful mainly for testing.

When commands are executed by Aegis, it ensures that the AEGIS_PROJECT, AEGIS_CHANGE, AEGIS_ARCH, LINES and COLS environment variables are set appropriately. The project configuration file's project_specific field is also consulted, looking for value's whose name starts with "setenv:" and sets the corresponding environment variable. All of the substitutions described by aesub(5) are available. For example: specifying a PATH and a SEARCH_PATH to be used for all commands may be set as follows:

project_specific =
[
  {
    name = "setenv:PATH";
    value = "/usr/bin:/bin";
  },
  {
    name = "setenv:SEARCH_PATH";
    value = "${search_path}";
  },
];

As many environment variables as desired may be specified in this way.
