Watch several log files in a single window

It works like a "tail -f" on several files.

Use the number keys 0-9 to set a baseline in the numbered window.

Pressing "b" let you scroll back in one of the windows.

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
multitail -l 'ssh machine1 "tail -f /var/log/apache2/error.log"' -l 'ssh machine2 "tail -f /var/log/apache2/error.log"'

this way you have the multitail with all its options running on your own machine with the tails of the two remote machines inside :)

Know a better way?

If you can do better, submit your command here.

What others think

um... Why would I want to install (and use) a second command that works exactly like tail -f?

It does not work exactly like tail -f

Comment by qubyte 251 weeks and 3 days ago

@ozymandias because it works a little differently than tail -f in that it is intended to follow multiple files, hence the 'multi' part of the multitail name. Neat command!

My experience:

multitail takes 100% of CPU on very busy systems.

Tailing weblogic logs was so horrible, I've had to shot it down.

For messages/syslog it should do just fine.

another option is:

sudo grc tail -f /var/log/foo
