Flogging your Files

Why Grep When You can Flog?

As a UNIX sysadmin I find myself spending a significant amount of time sifting through log files with grep's, pipes and more grep's. A pretty typical scenario when sifting through log files is usually something like this: 

% cat syslog |  grep "Jul 27"

[...hundreds of lines...]
LINE 1234: Jul 27 03:12:19 server2 sendmail[20573]: [ID 801593 mail.info] l6R7BUF0020573: host48-184.pppoe.inetcomm.ru did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
LINE 1235: Jul 27 03:12:19 server2 sendmail[20573]: [ID 801593 mail.info] l6R7BUF0020573: host48-184.pppoe.inetcomm.ru did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
LINE 1236: Jul 27 03:12:22 server2 sendmail[20574]: [ID 801593 mail.info] l6R7BYWq020574: host48-184.pppoe.inetcomm.ru did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
[...still more lines...]

That's usually followed by progressively tacking on more greps to whittle the output down to what I'm looking for: 


% cat syslog |  grep "Jul 27" | grep -v 2006 | grep sendmail | grep l6R7BUF0020573
Jul 27 03:12:19 server2 sendmail[20573]: [ID 801593 mail.info] l6R7BUF0020573: host48-184.pppoe.inetcomm.ru did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
