This article will explain in detail the process of using linux's pidof command to return to the running program ID. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The pidof command is used to retrieve the specified command and return the corresponding process ID. Where program is the name of one or more commands or processes. When you need to terminate a process, the traditional practice is to use the ps command to list all processes, use the grep command to select the target process, and then use the kill command to terminate the process.

With the pidof command, the combined command of ps and grep can be omitted and the process ID of the specified command can be written directly to standard output.

Syntax format: pidof [parameters]

Common parameters:
