Synopsis
|
|
--------
|
|
|
|
.. BEGIN SYNOPSIS
|
|
|
|
.. synopsis::
|
|
|
|
string trim [-l | --left] [-r | --right] [(-c | --chars) CHARS]
|
|
[-q | --quiet] [STRING ...]

Description
|
|
-----------
|
|
|
|
.. BEGIN DESCRIPTION
|
|
|
|
``string trim`` removes leading and trailing whitespace from each *STRING*. If **-l** or **--left** is given, only leading whitespace is removed. If **-r** or **--right** is given, only trailing whitespace is trimmed.
|
|
|
|
The **-c** or **--chars** switch causes the set of characters in *CHARS* to be removed instead of whitespace. This is a set of characters, not a string - if you pass ``-c foo``, it will remove any "f" or "o", not just "foo" as a whole.
|
|
|
|
Exit status: 0 if at least one character was trimmed, or 1 otherwise.
