In the grep's info page I find the following which works as said. But
I want to know why. What does the [c] do in this case?
------------------------
7. Why do people use strange regular expressions on `ps' output?
ps -ef | grep '[c]ron'
If the pattern had been written without the square brackets, it
would have matched not only the `ps' output line for `cron', but
also the `ps' output line for `grep'.
