Finding an exact process name | LinuC Level 1 101 Exam original practice question

1.01.4Basic

Find only processes whose name is exactly sshd.

Exclude a name such as sshd-helper.

Which command is appropriate?

Hint 1: Focus on the requirement

The process name must match the pattern as a whole, so use the exact-name filter.

Hint 2: Key terms

Review the short definitions before comparing the process and job-control choices.

pgrep: A command that searches processes and prints matching process IDs.
-x: The exact-match option that requires the complete process name to match.
Process name: The name field used by a process search command.
PID search: Finding process identifiers from attributes rather than listing every process.

Detailed explanation

Incorrectps -x sshd

Incorrect. ps does not use this exact-name search syntax.

Incorrectkill -x sshd

Incorrect. kill sends signals and does not search process names this way.

Incorrectjobs -x sshd

Incorrect. jobs is limited to shell-managed jobs.

Correctpgrep -x sshd

Correct. pgrep -x sshd selects exact process-name matches.

An example you can run in a temporary verification environment.

pgrep --help | grep -E -- '--exact|-x'

-x/--exact optionのhelp

Environment: procps-ng系pgrep help
Use a disposable process or test shell when checking lifecycle commands.
Exact output and option names can vary slightly by distribution and tool version.

Foundation review

-x excludes names with extra characters; matching a full command line is a different pgrep mode.

Confirm which name field the platform exposes before relying on an exact process-name match.
