Question
Which commands list the process IDs (PIDs) for the running processes on a Linux host? (Select TWO.) ps echo Crontab pidof ls
Solution
The two commands that list the process IDs (PIDs) for the running processes on a Linux host are:
-
ps: This command displays information about a selection of the active processes. If you want to see every process on the system using standard syntax, you can useps -e. -
pidof: This command finds the process ID of a running program. It takes the program name as an argument and returns the process ID.
The other commands listed (echo, Crontab, ls) do not provide information about running processes or their PIDs.
