70 Part I . Linux First Steps Moving, Copying, and Deleting Files Commands for moving, copying, and deleting files are fairly straightforward. To change the location of a file, use the mv command. To copy a file from one location to another, use the cp command. To remove a file, use the rm command. Here are some examples: $ mv abc def $ mv abc ~ $ cp abc def $ cp abc ~ $ rm abc $ rm * Of the two move (mv) commands, the first moves the file abc to the file def in the same directory (essentially renaming it), whereas the second moves the file abc to your home directory (~). The first copy command (cp) copies abc to the file def, whereas the second copies abc to your home directory (~). The first remove command (rm) deletes the abc file; the second removes all the files in the current directory (except those that start with a dot). For the root user, the mv, cp, and rm commands are aliased to each be run with the -i option. This causes a prompt to appear asking you to confirm each move, copy, and removal, one file at a time, and is done to prevent the root user from messing up a large group of files by mistake. Another alternative with mv is to use the -b option. With -b, if a file of the same name exists at the destination, a backup copy of the old file is made before the new file is moved there. Using the vi Text Editor It s almost impossible to use Linux for any period of time and not need to use a text editor. This is because most Linux configuration files are plain text files that you will almost certainly need to change manually at some point. If you are using a GUI, you can run gedit, which is fairly intuitive for editing text. There s also a simple text editor you can run from the shell called nano. However, most Linux shell users will use either the vi or emacs command to edit text files. The advantage of vi or emacs over a graphical editor is that you can use it from any shell, a character terminal, or a character-based connection over a network (using telnet or ssh, for example) no GUI is required. They also each contain tons of features, so you can continue to grow with them. This section provides a brief tutorial on the vi text editor, which you can use to manually edit a configuration file from any shell. (If vi doesn t suit you, see the Exploring Other Text Editors sidebar for other options.) Note
