PS

• Kill all process using string:

      $ ps -ef | grep PROCESS | grep -v grep | awk '{print $2}' | xargs kill -9
  
  **Usage**: Kills all PIDs matching the search term of “PROCESS”. Be careful what you wish for :)
  

• Find information about process by name:

      $ ps ax | grep <process_name>
      $ ps ax | grep <process_name> | grep -v grep
  
  **Usage**:
  
      ps ax | grep apache2
      ps ax | grep [Aa]pache2 #This will only show apache process (without grep)
      ps ax | grep apache2 | grep -v grep
  

• Kill pts:

  $ ps -t pts/1 | awk '/[0-9]/ {print $1}' | xargs sudo kill -9
