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 zan
