Introduction

The pidof command in Linux is a useful tool for finding the process ID (PID) of a running program. It can be used to quickly identify the PID of a process, which can then be used to manage or terminate the process. The pidof command is available on most Linux distributions and is part of the procps package.

Examples

The pidof command in Linux is used to find the process ID (PID) of a running program based on its name. It is useful for shell scripts that need to kill or restart a program based on its name.

Syntax:

pidof [options] [program name]

Options:

-s: Display only the first PID found for each program name.
-x: Match the exact name of the program.
-o: Specify a PID to exclude from the search.

Example:

To find the PID of the program named “firefox”:

$ pidof firefox

This will return the PID of the Firefox process.

Pidof Linux Command

The pidof command in Linux is used to find the process ID (PID) of a running program or process. It is a simple command that takes the name of a program as an argument and prints out the PID of the process. This command is useful for finding out the PID of a process that is already running, so that it can be killed or manipulated in some way.

The syntax for the pidof command is as follows:

pidof [options] program_name

The options for the pidof command are as follows:

• -s: This option prints out only the first PID found.
• -o: This option prints out only the PIDs of processes owned by the current user.
• -x: This option prints out only the PIDs of processes that have the same name as the program name given.

For example, to find the PID of the program called “firefox”, you would use the following command:

pidof firefox

This command will print out the PID of the process running the program “firefox”. You can then use this PID to manipulate the process in some way, such as killing it or sending it a signal.
