$ help command
command: command [-pVv] command [arg ...]
Execute a simple command or display information about commands.

information about the specified COMMANDs. Can be used to invoke commands
on disk when a function with the same name exists.

the standard utilities
-v print a description of COMMAND similar to the `type' builtin
-V print a more verbose description of each COMMAND
Exit Status:
Returns exit status of COMMAND, or failure if COMMAND is not found.
- denton-scratch 5y agoI didn't know about the "help" command in bash. I've always gone to "man bash", and then scrolled up and down for an hour or so. Or just cranked-up a search engine. So thanks for that.
- coolgeek 5y agoApparently, there's an "info" command, as well
- MonkeyClub 5y agoThough info isn't POSIX compliant. Not to mention that most distributions completely ignore it and don't populate it with a program's info documentation -- even when such exists.
- greyfade 5y agoNeither is Bash. And, being GNU projects, Bash and `info` generally come hand-in-hand.
- fractalb 5y agoWow. I never knew this. I tried scouring through the bash manpage to get hold of its inbuilt commands. Thanks.
