===== Description =====
|
||
|
|
This compound command provides a kind of menu. The user is prompted with a //numbered list// of the given words, and is asked to input the index number of the word. If a word was selected, the variable ''<NAME>'' is set to this word, and the [[syntax:basicgrammar#lists | list]] ''<LIST>'' is executed.
|
||
|
|
|
||
|
|
If no ''in <WORDS>'' is given, then the positional parameters are taken as words (as if ''in "$@"'' was written).
|
||
|
|
|
||
|
|
Regardless of the functionality, the //number// the user entered is saved in the variable ''REPLY''.
|
||
|
|
|
||
|
|
Bash knows an alternative syntax for the ''select'' command, enclosing the loop body in ''{<nowiki>...</nowiki>}'' instead of ''do <nowiki>...</nowiki> done'':
|
||
|
|
<code>
|
||
|
|
select x in 1 2 3
|
||
|
|
{
|
||
|
|
echo $x
|
||
|
|
}
|
||
|
|
</code>
|
||
|
|
This syntax is **not documented** and should not be used. I found the parser definitions for it in 1.x code, and in modern 4.x code. My guess is that it's there for compatiblity reasons. This syntax is not specified by POSIX(R).
