NAME

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
