pgrep is a command-line utility that allows you to find the process IDs of a running program based on given criteria. It can be a full or partial process name, a user running the process, or other attributes.

The pgrep command is a part of the procps (or procps-ng) package, which is pre-installed on nearly all Linux distributions.
