Commands for Managing Processes

Processes could be managed using the ps command and the nice command.

The  ps  command  could  be  used  to  check  the  active  processes  on  a  system  and  to  show  detailed information about the processes. A nice command is used to modify the priority of a timesharing process.

Nice executes a command within a lower CPU scheduling priority. That is used if the increment argument (in the range 1-20) is provided; if not, an increment of 10 is supposed. The invoking procedure (commonly the user's shell) must be in the time-sharing scheduling class. The super-user might run commands with priority that is higher than normal through using a negative increment. For instance, -10.
