To possibly expand on and/or clarify what others have said: Some commands aren't separate programs (which get man pages), but shell built-in commands (which are documented in the shell's own man page). The easiest way to tell which one a given program is is via the 'type' command (which itself is a shell builtin): $ type history history is a shell builtin $ type man man is hashed (/usr/bin/man) Once you've determined that a particular command is a shell builtin, you can either look it up in the man page of whatever shell you're running, or - at least with bash in a standard installation, and probably in other shells as well - look it up directly with the 'help' command: $ help history [output snipped, its over two dozen lines long] However, that documentation is purely functional; it doesn't delve into the possible ramifications of ways to use the command in various contexts, so it might fall under the same "too narrowly focused" as the Q&A you report having found online. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. -- George Bernard Shaw
