ossec-regex

The ossec-regex program is used to validate a regex expression.

The pattern should be enclosed in single quotes to help prevent any unintended interactions with the shell.

The syntax for ossec-regex is as follows:

/var/ossec/bin/ossec-regex '<pattern>'

It then reads strings from stdin and outputs matches to stdout.

+OSRegex_Execute and +OS_Regex are displayed if a match is successful.
