UNIX for Dummies Questions & Answers

Hi,
I want to know how we can view two or three logs which are dynamically getting updated from a single/same putty window with tail commnad.

Thanks.

GNU screen is a nice tool that can allow this kind of things

what is this GNU screen. Can you pls tell in detail how we can do that, pls.

I don't have access to download. is that not possible with unix command tail or with any other command?

if this is Linux, I was under the impression that tail could be used to monitor multiple files.

Code:

tail -f file1.log file2.log

if not Linux, you can try putting one of the tail commands in the background and then leave last entered tail running. although I've had varying results with this, ymmv

Code:

tail -f file1.log &
tail -f file2.log

I'd also like to see an example of doing that with `screen', because I've primarily used `screen' to detach screens and get them back after a while. But here the task is (if I understand it correctly) to see the tail of 3 different files and updating them regularly, so I'd rather go for:

Code:

watch -n3 tail ${file1} ${file2} ${file3}

one could also experiment with the `window' command to get the tails of all each file into separate frames, but I'm not quite familiar with `window' myself.

yeap, to my mind `tail -f' is a very nice solution, thanks unxscorob, I didn't know about the option. It works on NetBSD too.

screen can split a single tty into 3 , so that you can launch one tail -f logfile in each and every of the different screen.

How is that? Can you tell me the command or what to do for this? I am on support this functionality is extremely required for me, because I need to monitor 3 4 managed serv re logs at the same time.


Thanks.
