 +====== Using Linux ======
 +The SE group uses Linux as operating system for most of its machines. This page aims to give you some assistance in finding your way around such a system. Please contribute to this page if you think something is missing.
 +Students in the SE-lab will find some Linux oriented books there. Asking a fellow student for information can also be very helpful. And of course there is always the WWW; just pick one of the 361.000.000 hits about Linux to help you on your way....
 +Many people use a Linux system through an //ssh// connection from a Windows system (the serack systems), others use Linux as their desktop system.
 +===== Shell =====
 +A //shell// is the program that prints prompts like ''​[me@se]$'',​ accepts lines of text with names of commands and their arguments, executes those commands, and echoes text printed by the command.
 +A commonly used shell is ''​bash''​.
 +Below are a few of the basic shell commands to get you started. If you need more information look at one of the many Linux books, read Linux related web pages, or simply ask someone else. Linux itself also has lots of additional information in help files, manual pages, etc.
 +===== Basic shell commands =====
 +^ Linux_Command ^ Description ^
 +| passwd | Change your password. Enter your current password, followed by your new password twice. Use a strong password, of at least eight characters with both UPPER and lowercase characters. |
 +| mkdir //name// | Create a new directory with name //name// |
 +| rmdir //name// | Permanently delete directory //name//. Can only be done if the directory is empty |

 +| ls | Shows a list of the content of the current directory, excluding the hidden files |
 +| ls //​directoryname//​ | Shows a list of the content of //​directoryname//,​ excluding the hidden files |
 +| cp //name name2// | Copy file //name// from the current directory to directory //name2//, if such a directory exists. Copy file //name// to file //name2// in the current directory, in case directory //name2// does not exist. You will **//not//** be warned if this action overwrites an existing file //name2// |
 +| mv //name name2// | Move the file //name// to directory //name2//, if such a directory exists. Move (rename) file //name// to //name2// in the current directory if directory //name2// does not exist. You will **//not//** be warned if this action overwrites an existing file //name2// |
 +| rm //name// | Remove (delete) file //name//, without asking 'Are you sure?'​. |
