public string[] grep (string regex, string path, Grep? optargs) throws Error
return lines matching a pattern
This calls the external grep program and returns the matching lines.
The optional flags are:
extended Use extended regular expressions. This is the same as using the *-E* flag.
fixed Match fixed (don't use regular expressions). This is the same as using the *-F* flag.
insensitive Match case-insensitive. This is the same as using the *-i* flag.
compressed Use zgrep instead of grep. This allows the input to be compress- or gzip-compressed.
