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.
