I figured it would be a great idea to have posted a list of UNIX commands that are necessary, and fundamental. It helped today with the Mac Probook.

Following is a brief list of simple UNIX commands that will help you move around the file system, examine files, copy or delete files, do housekeeping on your account, and communicate with other users on our or other systems. For online help with any command, e.g. the ls command, type man ls .

FILE OPERATIONS:

ls                      list files
cp                      copy files: cp /path/name newname
mv                      move or rename files: mv name newname
rm                      remove (i.e. delete) files: rm name
chmod                   change mode of file permissions: chmod xxx name
cat                     scroll file contents: cat name
more                    page file contents (spacebar to continue): more name
less                    better pager than more? (q to quit): less name
view			view file contents (:q to quit): view name
vi                      visual text editor (:wq to save and quit): vi name
pico                    pico text editor (Ctrl-X to quit): pico name

DIRECTORY OPERATIONS:

mkdir                   make (create) new directory: mkdir Name
cd                      change directory: cd /path/name
cd 			change to your home directory: cd
