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 characters in CHARS to be removed instead of whitespace. 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
