ls

List files

ls, used alone, will print the contents of the current directory. If it is followed by a path to a directory, will print its contents.

Options (letters or words preceded by “-” or “–”, respectively) will change how and what is printed.

• ls -a or ls --all
  • Will print all contents of the working directory, including hidden files (which start with a dot, eg. .ssh).
• ls -alhs Desktop or ls --all -l --sort --human Desktop
  • Will print all the contents (-a or --all including hidden files) in the form of a list (-l) that includes the permissions of each file, their owners, the date of the last modification and their size in human format (-h or --human; 4Kb instead of 4000b) and sort them alphabetically (-s or --sort; other options can be used to change how to sort the files).

To know other options for ls, run man ls or ls --help
