Bash Self-Sufficiency: apropos Search

When you know the task but not the command name, apropos is the fastest bridge from idea to action. It searches manual page names and one-line summaries, then returns a shortlist you can inspect with man.

Practice the Command

Use apropos with a keyword that describes your goal.

Try the command

Which topic are you searching for?

Build the command
apropos
Terminal
~$apropos directory
ls (1) - List information about the FILEs (the current directory by default). cd (1) - Change the current directory to directory. pwd (1) - Print the full filename of the current working directory. mkdir (1) - Create the DIRECTORY(ies), if they do not already exist. rmdir (1) - Remove empty directories. mv (1) - Rename SOURCE to DEST, or move SOURCE(s) to DIRECTORY. tar (1) - Create, list, or extract tar archives. find (1) - Search for files in a directory hierarchy. grep (1) - Search for PATTERNS in each FILE.

From vague goal to concrete commands:

Terminal
~$apropos process

Why This Matters

Strong command-line users do not memorize everything. They build a loop: search with apropos, inspect with man, run with confidence. That workflow is faster and safer than guessing syntax under pressure.

Common Mistakes

  • Using keywords that are too broad: Start broad, then refine.
  • Stopping at the first match: Scan multiple matches before choosing.
  • Skipping verification: Open man <command> before production use.
