Usage notes
Exit values
The command:
alias ls="ls –C"
defines ls as an alias. From this point onward, when you issue an ls command, it
produces multicolumn output by default.
alias in the tcsh shell examples
To alias the !! history command, use \!-1 instead of \!\!. For example:
alias mf ’more \!-1$’
creates an alias for looking at the file named by the final argument of the previously
entered command. Example output would be the following:
alias mf ’more \!-1$’
echo "We love tcsh." > file1
mf
We love tcsh.
"file1" (EOF)
where mf pulls the last argument of the previous command (file1), and then
displays that file using the more command.
alias uses the following localization environment variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES
v NLSPATH
See Appendix F, “Localization” for more information.
1. alias is a built-in shell command.
2. Because exported aliases are only available in the current shell environment
and to the child processes of this environment, they are not available to any
new shell environments that are started (via the exec sh command, for
example). To make an alias available to all shell environments, define it as a
nonexported alias in the ENV file, which is executed whenever a new shell is
run.
0 Successful completion
1 Failure because an alias could not be set
2 Failure because of an incorrect command-line option
If you define alias to determine the values of a set of names, the exit value is the
number of those names that are not currently defined as aliases.
