aesub - substitute and echo strings
aesub [ option... ] string ...
The aesub command is used to perform the usual aesub(5)
substitutions on its command line arguments, and then echo them to the
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.
The following options are understood:
- 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.
This option may be used to obtain more information about how to use the
- -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.

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
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.
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.
