Here is a brief list of frequently/commonly used UNIX commands:

  • cp – copy files
  • scp – secure copy files
  • ls – list files (ls -l lists files with attributes)
  • chmod – change attributes of files, etc. (chmod u+x … makes a file executable for you)
  • cd – change directory
  • mv – move files
  • rm – remove files
  • pwd – to find out in which directory you are currently

You can use e.g. “man ls” on the command line to find out more about a specific command. You could also try to google details …

If you have found out other useful commands, tricks, etc. let us know!
