SYNTAX _________________________________________________________________________________ How syntax works (Expanded for ease of understanding): command applies to: directory | | cd ~/.ssh command applies to: filename applies to: new filename | | | mv index.html home.html (careful! This overwrites home.html if it exits) command applies to: filename applies to: existing directory (and current or new filename) || | | mv portrait.jpg images/portrait2.jpg COMMANDS _________________________________________________________________________________ pwd # see your present working directory touch (filename) # create a new file clear # clears the screen by moving it up, does not delete cd filename # change directory cd directoryname # will autocomplete to the change in file name up arrow # cycle through commands down arrow # cycle through commands cd .. # move up a directory cd / # move to the root directory cd ~ # go to the home directory cd - # go to the previous directory we just came from cd ../.. # move up two directories cd ~/.ssh # move into the user directory with a specific subdirectory ls # list files and directories ls -a # list all files including hidden files ls -l # list long format ls -la # list all files and in long format cp one two # copy mv # move and rename rm # remove file (delete) NO UNDO FOR THIS!!! won't remove a directory rm *.jpg # remove all files ending in .jpg rm -r # remove recursively.
