tail -f monitoring
Is there any file on UNIX that changes periodically so that I could use tail -f command to watch changes? I was searching a long time and I didn't find nothing (I'm newbie to UNIX so it's not a surprise to me though)

Thanks for help Smilie

Wait, are you just looking for a random file that is constantly appending itself so you can watch it change? I'm not sure I'm understanding what your goal is here.

well, I'm looking for a system file that periodically changes or at least quite often.

Thank you for reply

I didn't find the files, I have a "student" account but even so I should be able to see them, shouldn't I? They are not hidden, I tried ls -a

If it is just to test the tail -f command, you can make a little script that will write the current date into a file and watching it with tail -f

Put this in a file:
Code:
#!/bin/sh

while true; do
        sleep 5
        date >> /tmp/dte
done

Make that file executable (chmod +x that-file), execute it and watch the result in another session with tail -f /tmp/date.

To stop the script: CTRL-C in the session where you executed the file.

Thank you!

I was looking for a file because it would be easier than two sessions Smilie But this will do the job too.
