Search exim's main log
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 \(oqliteral\(cq, 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.
