NAME
check-regexp - test regular expressions from the command line
SYNOPSIS
check-regexp regular expression string1 string2 ...
DESCRIPTION
check-regexp (GNU Source-highlight)
You simply pass as the first command line argument the regular
expression and then the strings you want to try to match.
It is crucial, in order to avoid shell substitutions, to enclose both
the expression and the strings in single quotes.
The program then prints some information about the possibly successful
matching.
In the output the what[0] part represents the whole match, and the
what[i] part represents the i-th marked subexpression that matched.
The program also prints possible prefix and suffix.
OPTIONS
This program follows the usual GNU command line syntax, with long
options starting with two dashes (‘-’). A summary of options is
included below.
-h, --help
Print help and exit
-V, --version
Print version and exit
