TRIM

NAME

trim - Strip whitespace (or other characters) from the end of a string.

SYNOPSIS

trim(str,charlist)

PARAMETERS

charlist

Optionally, the stripped characters can also be specified using the
charlist parameter. Simply list all characters that you want to be

" " (ASCII 32 (0x20)), an ordinary space.
"\t" (ASCII 9 (0x09)), a tab.
"\n" (ASCII 10 (0x0A)), a new line (line feed).
"\r" (ASCII 13 (0x0D)), a carriage return.
"\x0B" (ASCII 11 (0x0B)), a vertical tab.

RETURN

The trimmed string.

EXAMPLES

Note: In the followings examples, the _ between the { should be removed to make it work.

in:  res={_{trim(charlist:"0..9","098aaa098")}}.
out: res=aaa
