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.
