    That's a good question. Using grep has a brief but steep learning curve. Most UNIX commands do. Once you get the basics, you can put grep to powerful use.

    In the most basic usage, grep will search through text looking for the search string. If you want to look for commands containing the string 'http' you would simply use:

    ..... | grep http | ....


    Grep stands for global regular expression parser and is a magnificently powerful tool. The important thing to take out of that mouthful is 'regular expression' which is a formal language for representing elaborate wildcards for searching. For example, a period matches any single character, so .at would match bat, cat, rat, and so on. Used in a grep statement, it would match that regular expression anywhere in the line, so it would also match brat and bats. Regular expressions would be a great idea for a series of rec.pes.

    i think you might want to look into the killall command

    a kill -9 doesnt give the process the possibility to clean up; to exit "voluntarily". can screw up its data.

    always try a kill (without -9) first

    You can use the following command :

    kill -9 `ps -ef | grep <process-name> | grep -v grep | awk '{print $2}'`

    Just make sure that you keyin the correct process name in the above command.

    egrep -v "ps|sh|PID" file | awk '{print $1}' | xargs kill
