ls - This command lists the contents of the current directory

  • ls -l This is the same command with a flag (-l) which lists the contents with more information, including access permissions
  • ls -a Same ls command but this time the -a flag which will also list hidden files. Hidden files start with a . (period)
  • ls -la Stringing flags together

cd - This will change your location to a different directory (folder)

  • cd /projects/myusername.proj
  • Typing cd with no arguments will take you back to your home directory

mv - This will move or rename a file

  • mv project1.txt project2.txt
  • mv project2.txt /projects/myusername.proj/

rm - This will delete a file
