Top command in batch mode

Run the following command to begin top in batch mode, logging to a file called TOP_LOG:

top icbd .1 | egrep -v “top|Tasks|Cpu|Mem|Swap|PID|top icbd|^$|tee -a” | tee -a top_log

1. Code breakdown:
   

   top icbd .1	Run the top command with the idle processes being shown, full command line paths being shown, running inbatch mode, and with the delay set to .1seconds so that it quickly refreshes.
   egrep -v “top|Tasks|Cpu|Mem|Swap|PID|top icbd|^$|tee -a”	Use the egrepcommand with the -vflag to not show any lines that include top,Tasks, Cpu, Mem,Swap, PID, top icbd,^$ which is any blank line, or tee -a. This way we only see lines from top that have process information.
   tee -a TOP_LOG	Finally use the teecommand with the -append flag to simultaneously write the data from the topcommand out to a file called TOP_LOG.

2. After you’ve let this run for some time to gather data, you can go ahead and hit Ctrl-C to stop thetop command from gathering more data.
3. cat TOP_LOG| sort -k9| tail -20| sort -k2
4. You should end up with something that looks like this:

6. Once you are done reviewing the data in our TOP_LOGfile you can run the following command to remove this file:rm -rf ./TOP_LOG
