Format
Description
set [±abCefhiKkLmnPpstuvx–] [±o[flag]] [±Aname][parameter ...]
tcsh shell:
1. set [-r]
2. set [-r] name ...
3. set [-r] name=word ...
4. set [-r] [-f|-l] name=(wordlist) ...
5. set name[index]=word ...
Calling set without arguments displays the names and values of all shell variables,
sorted by name, in the following format:
Variable="value"
The quoting allows the output to be reinput to the shell using the built-in command
eval. Arguments of the form –option set each shell flag specified as an option.
Similarly, arguments of the form +option turn off each of the shell flags specified as
an option. (Contrary to what you might expect, – means on, and + means off.)
Note: All of the set options except ±A, –s, –, and –– are shell flags. Shell flags can
also be set on the sh command line at invocation.
set in the tcsh shell
tcsh shell: See format section to view the forms described below.
1. The first form of the command prints the value of all shell variables. Variables
which contain more than a single word print as a parenthesized word list.
Variables which are read-only will only be displayed by using the -r option. For
forms 2, 3 and 4, if -r is specified, the value is set to read-only.
2. The second form sets name to the null string.
3. The third form sets name to the single word.
4. The fourth form sets name to the list of words in wordlist. In all cases the value
is command and filename expanded. If -f or -l is specified, set only unique
words keeping their order. -f prefers the first occurrence of a word, and -l the
last.
5. The fifth form sets the index’th component of name to word; this component
must already exist.
These arguments can be repeated to set and/or make read-only multiple variables
in a single set command. However, variable expansion happens for all arguments
before any setting occurs. Also, ’=’ can be adjacent to both name and word or
separated from both by whitespace, but cannot be adjacent to only one or the other.
For example:
set -r name=word and set -r name = word
