Ubuntu Manpage: aesub - substitute and echo strings

NAME

        aesub - substitute and echo strings

SYNOPSIS

        aesub [ option...  ] string ...
        aesub -Help
        aesub -VERSion

DESCRIPTION

        The aesub command is used to perform the usual aesub(5) substitutions on its command line arguments, and
        then echo them to the standard output.

   Shell Script Quoting
        The aesub(1) command is often used in shell scripts.  It is important to remember that the shell will do
        its own substitutions on the command line argument before it invokes the aesub(1) command.  Usually, you
        don't want this to happen, so you need to use single (') quotes to do this.  (The shell continues to
        substitute inside double (") quotes.)

        Quote aesub(1) arguments using ' single ' quotes.

OPTIONS

The following options are understood:

-BaseLine
This option may be used to specify that the project baseline is the subject of the command.

-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.

-File filename
Take the text to be substituted from the specified file. The filename `-' is understood to mean
the standard input.

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

-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.

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 aesub are long, this means
ignoring the extra leading '-'. The "--option=value" convention is also understood.

EXIT STATUS

        The aesub command will exit with a status of 1 on any error.  The aesub 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.
