Quickly locate relevant man pages and command names when the right word is just out of reach. 17.02.2026 | reading time: 2 min When he remembers a task but not the command name, `apropos` is the fastest way to search short manpage descriptions and discover the right tool. Try this quick search Run a search and inspect results; this shows common output for a search on "ssh": ``` $ apropos ssh ssh (1) OpenSSH SSH client (remote login program) ssh-keygen (1) OpenSSH key generation utility sshd (8) OpenSSH daemon ``` Narrow, refine, and update Limit searches by manual sections, use regular expressions for complex patterns, and remember the search uses the whatis database, so run `sudo mandb` to include new or local pages before expecting results. Practical tricks in real workflows Combine `apropos` with a short list of keywords to zero in quickly, pipe results to `grep` to filter entries, or use the logical AND mode to require multiple words when he needs very specific matches. Related commands to know `man -k` is an alias for `apropos`, `whatis` shows single-entry descriptions, and `mandb` rebuilds the searchable database that `apropos` consults. Final thought and next step Make `apropos` part of his toolkit: it saves time and reduces guesswork when exploring a system, and if he wants to deepen his Linux skills, consider formal study such as CompTIA Linux+ or LPIC-1 with intensive exam preparation at bitsandbytes.academy.
