			One of the most useful yet unknown to beginners: <TAB> completes anything at any moment, If there are ambiguities, <TAB> will complete only the unambiguous part. Two times <TAB> shows all alternatives when there are ambiguities.

			Try <TAB><TAB> on an empty line to get a list of all commands that are "known" to the shell (will not find commands that are not in $PATH and so would need full pathname to invoke them)

	'''Understand what a command does before you type it'''		'''Understand what a command does before you type it'''
	Fundamentally you should understand what a command does before typing it in and pressing enter. If you have a linux desktop ~~distribution, like Ubuntu~~, you can normally type the command with the parameter <code>--help</code> to get a list of options, i.e. <code>ls --help</code>, or look up manual pages if installed, with:		Fundamentally you should understand what a command does before typing it in and pressing enter. If you have a linux installed on your desktop PC, there you can normally type the command with the parameter <code>--help</code> to get a list of options, i.e. <code>ls --help</code>, or look up manual pages if installed, with the most helpful linux command <code>man</code> for "manual", like:

	man ls [enter]		man ls [enter]

	to find out what ~~the commands~~ are and ~~their~~ options. However ~~you can~~'t do this on the ~~tablets~~ though as the ~~tablets use cut down embedded commands~~, (~~BusyBox~~ - ~~I think?~~), so look at [http://ss64.com/bash Linux commands] or [http://www.busybox.net/downloads/BusyBox.html ~~Busybox~~ list of Linux commands and options for each one]		or

			man man [enter]

			to find out what a command does and what are and the options it allows.

			However on maemo the default shell is busybox which has lots of commands like <code>ls</code> built in, and most of them are crippled in functionality so don't support a really helpful --help function. Also the <code>man</code> command is not available on standard maemo. So maemo NITs are basically a hostile environment for beginners to learn about linux.

			There are ways to mitigate this:
			* install man. The pkg is available e.g. here:[http://maemo.org/packages/view/man-db-n900/] and also in your application manager when you got the extras-devel catalog enabled.
			* install bash (version 3 or 4), a proper fullsize shell though without many builtins. (http://maemo.org/packages/view/bash3/ http://maemo.org/packages/view/bash4/, again also in your application manager, from extras catalog.
			* install proper original tools to replace the crippled ones of busybox, when you already installed bash. Refer to e.g. [[User:Joerg_rw/tools]]

			If you're reluctant to do all of the above (installing man package mandb-N900 is strongly recommended anyway), you may look up general linux cmdline help here: [http://ss64.com/bash Linux commands], and details about crippled busybox here: [http://www.busybox.net/downloads/BusyBox.html list of Busybox Linux commands and options for each one].
