# string-trim - remove trailing whitespace

## Synopsis

    string trim [-l | --left] [-r | --right] [(-c | --chars) CHARS]
                [-q | --quiet] [STRING ...]

## 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.

## Examples

    >_ string trim ' abc  '
    abc

    >_ string trim --right --chars=yz xyzzy zany
    x
    zan
