doing the opposite gave me what I expected: echo /home/silentm/log/file.machine.log | cut -d . -f 1 gives me /home/silentm/log/file

I am trying to find a way to test if the file ends in .log?

How might I do that.

If you really want to >cut< .log you could use basename /home/silentm/log/file.machine.log .log.

echo /home/silentm/log/file.machine.log | sed 's/^.*.([^.]*)$/\1/'

Will work all the time.

/home/silentm/log/file.machine.log --> log /home/silentm/log/file.machine.log.1.2.3.4 --> 4

If you want to get the dot too, just use 's/^.*(.[^.]*)$/\1/' instead.
