Name

pgbool — return "f" (false) or "t" (true), depending on input data

DESCRIPTION

The filter returns "f" (false) if the input is undefined, 0, f or false (in a case-insensitive manner). Otherwise, it returns "t" (true).

EXAMPLES

No examples are available at this time. We do consider this a problem and will try to supply some.

NOTES

For more information on Perl Regular Expressions, pattern matching and character classes, see perlre(1).
