Hello,

I have to create shell script being myself real novice in scripting…
I was looking on the Internet for some script examples, but I don’t have the basic understanding of the shell. I was trying to do something with “ps” command without success.
For exemple total number of running process: ps ax | wc -l | tr -d ""
Executed from command line work nice, but once in the script like echo ‘ps ax | wc -l | tr -d ""’ return 1 which is not the right number of running process.

The script should do the following:

• Should check the running processes
• Display top five process (per cpu consumption)
• output the summary for:
  • total number of processes
  • number of process per user
  • most common process

ex.: process1
process2
process3
process1
result : process1

Is it too difficult to implement in pure bash script?

Many thanks in advance for any help.
