Working with Files and Directories in Linux
A very large proportion of all the work most users do from the command line, evenadvanced users, consists of few key activities and a fairly small number of common commands. Most of these have to do with locating, listing, creating, editing, and deleting files and directories. This article provides an overview of the most common file and directory-related tasks and the commands that you use to perform them.
Listing Files
The ls (list) command lists files in the current directory. The command ls has a very large number of options, but what you really need to know is that ls -l gives a “long” listing showing the file sizes and permissions, and that the -a option shows even “hidden” files—those with a dot at the start of their names.
Copying Files
The cp (copy) command copies a file, files, or directory to another location.
