exigrep [-l] pattern [log file] ...
The exigrep utility is a Perl script that searches one or more main log files for entries that match a given pattern. When it finds a match, it extracts all the log entries for the relevant message, not just those that match the pattern. Thus, exigrep can extract complete log entries for a given message, or all mail for a given user, or for a given host, for example.
The -l flag means 'literal', that is, treat all characters in the pattern as standing for themselves. Otherwise the pattern must be a Perl regular expression. The pattern match is case-insensitive. If no file names are given on the command line, the standard input is read.
If the location of a zcat command is known from the definition of ZCAT_COMMAND in Local/Makefile, exigrep automatically passes any file whose name ends in COMPRESS_SUFFIX through zcat as it searches it.
This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches would be greatly appreciated.
This manual page was stitched together from spec.txt by Andreas Metzler <ametzler at downhill.at.eu.org>, for the Debian GNU/Linux system (but may be used by others).
