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 zanyxzan
