How to use the help command: 2-Minute Linux Tips

The video tutorial explains the 'help' command in bash, which provides information on bash builtins. These are commands integrated into the bash shell, unlike standalone executables, so they lack manpages. To view all bash builtins, type 'help' in the command line. For specific builtins, use 'help' followed by the command name. The 'help' command works only with bash and related shells like R Bash. If you can't find a manpage for commands like 'suspend' or 'umask', the 'help' command might offer guidance.
