Linux pidof Command Examples To Find PID of A Program/Command

Best/Tutorial

The pidof command in Linux is used to find the process ID (PID) of a program or command. Here are some examples of how to use the pidof command:

  1. Find the PID of a specific process:
pidof process_name

where process_name is the name of the process you want to find the PID of. For example, to find the PID of the ssh service, you would use the following command:

pidof ssh

  1. Find the PID of multiple processes:
pidof process1 process2 process3

where process1, process2, and process3 are the names of the processes you want to find the PIDs of.

Note: The pidof command will return the PID of the first instance of the process it finds. If you have multiple instances of the same process running, you can use the pgrep command instead.

  1. Find the PID of a running process using pgrep:
pgrep process_name

where process_name is the name of the process you want to find the PID of. For example, to find the PID of the ssh service, you would use the following command:

pgrep ssh

This will return a list of all PIDs of the processes that match the name ssh.
