What command displays information about active processes?pkillpstrapkillpgrepI don't know

The command that displays information about active processes is pgrep.

Explanation:

• pgrep: This command looks through the currently running processes and lists the process IDs which match the criteria given. It’s commonly used to find processes by name.

Other commands listed:

• pkill: This command is used to kill processes based on a name or other attributes, but it does not display their information.
• pstrap: This is not a standard command in Unix/Linux systems related to process management.
• kill: This command is used to send a signal to a process (commonly used to terminate it), not to display information about active processes.

In summary, if you need to display or filter information about active processes, you should use pgrep.
