paternoster

A command line tool that call the given command for each input line matching the given regular expression pattern.

SYNOPSIS

paternoster [-h]

paternoster [-w] PATTERN COMMAND(S)

DESCRIPTION

paternoster read lines of text stream on the standard input and call COMMAND(S) for lines matching a given regular expression PATTERN.

If groups are specified in the regular expression pattern, only them are taken into account, else the whole matching pattern is considered.

You can specify several commands when using groups by separating them with spaces. If you indicate more commands than groups, the last ones will be silently ignored. If you ask for fewer commands, the last one will be duplicated across remaining groups.

EXAMPLES

  • Make the speakers beep for every FIXME found in a source code: `cat source.ext | paternoster "FIXME" "beep"

  • Play a sound for each error or warning on a compiler output (you must have the corresponding wav files somewhere in you path): make 2>&1 | paternoster ".*(error|warning): .*$" "play %s.wav"

  • Say out loud the error in a compiler output: make 2>&1 | paternoster ".*(error: .*)$" "espeak --punct=';{}()' '%s'"
