Show log files on console with changes
When writing any kind of log files you can of course show them on the console by opening them in any kind of editor be it
less or just a simple
cat. But you need to run the command every single time you run a process that writes something into the file.
A better way is to use
tail with the
-f option. With it you jump into the file and stay there. Any changes into the file will be shown immediately:
$ tail -f /tmp/error.log
