Which command allows you to display all processes that match the search term?

The pgrep command is specifically designed to search through currently running processes and filter them based on a search term. When you use this command, you can provide it with various parameters, including the name of a process, and it will display the process IDs (PIDs) of all active processes that match the specified criteria. This makes pgrep particularly useful for scripting and monitoring purposes where you want to identify specific running processes without overwhelming output.

In contrast, pkill is used to terminate processes that match a specific search term, and while ps can display information about running processes, it does not have built-in functionality for matching based on a search term directly. The top command provides a dynamic, real-time view of your system's processes but is not designed for searching or filtering based on a specific term. Therefore, pgrep stands out as the most effective command for displaying processes that match a search term.
