How can I use the watch command to run a bash script and monitor output file?
So I have a bash script "example.sh" that will write into an output file, say "tmp_output.txt". (It will empty the file and rewrite if data already exists in it)
How can I use the watch command so that it will run "example.sh" every two seconds and view the changes being made in "tmp_output.txt"?
The watch command needs to used within the bash script.
