How to find a specific process id for a running Application or Process in Linux

NOTE: Tested in Ubuntu 9.04

In this example we want to find the process id for Skype.

1. In the command line type in the command below
   {codecitation style=”brush: bash;”}pgrep -l skype{/codecitation}
2. This will list the process id together with the process name for Skype.
   -l = List the name of the process
   {codecitation style=”brush: bash;”}4322 skype{/codecitation}
3. To list only the process id type the command without the -l option
   {codecitation style=”brush: bash;”}pgrep skype{/codecitation}
4. This will only list the process id
   {codecitation style=”brush: bash;”}4322{/codecitation}
