Grepping a huge file (80GB) any way to speed it up?
grep -i -A 5 -B 5 'db_pd.Clients' eightygigsfile.sql This has been running for an hour on a fairly powerful linux server which is otherwise not overloaded. Any alternative to grep?

Find and kill a process in one line using bash and regex

The way I do it now is: [~]$ ps aux | grep 'python csp_build.py' user 5124 1.0 0.3 214588 13852 pts/4 Sl+ 11:19 0:00 python csp_build.py user 5373 0.0 0.0 8096 960 pts/6 S+ 11:20 0:00 grep python csp_build.py [~]$ kill 5124 How can I extract the process id automatically and kill it in the same line? Like this: [~]$ ps aux | grep 'python csp_build.
