A few useful commands

• tcsh: type this if your xterm/terminal starts out with "bash-x.xxx$"
• pwd: show current directory print working directory
• ls: show the contents of a directory. ls -a will also show files whose name begins with a dot. ls -l shows lots of miscellaneous info about each file. ls -t sorts the most recently changed to the top.
• cd directory: change directory. If directory is not specified, goes to home directory.
• mkdir name: create a directory
• rmdir name: delete a directory. The directory must be empty.
• cd: change directory back to main home directory
• cp old new: creates a file named new containing the same thing as old. If there was already a file named new, it is overwritten.
• rm file: delete a file
• mv old new: rename a file from old to new (also works for moving things between directories). If there was already a file nmed new, it gets overwritten.

Once you know what command you want, you can get more detailed syntax information by typing "command --help" e.g. "cp --help"

If you want to page through information a screenful at a time, type
command | more e.g. "ls | more" or "cd --help | more"
