6.1.5 help

Die Bash enthält eine Reihe von eingebauten Befehlen, die auch als Bultins bezeichnet werden. Die Hilfe zu diesen Befehlen erhalten Sie über den Befehl help, der ebenfalls Bestandteil der Bash ist.

Der Befehl ohne Parameter zeigt eine Liste der Bash-internen Befehle an.

dozent@linux37:~> help
GNU bash, version 2.05b.0(1)-release (i586-suse-linux)
These shell commands are defined internally.  Type `help' to see this list.
Type `help name' to find out more about the function `name'.
Use `info bash' to find out more about the shell in general.
Use `man -k' or `info' to find out more about commands not in this list.

A star (*) next to a name means that the command is disabled.
