It is very important for every Data Analyst/Scientist to be able to interact with the Command Line Shell. Let’s start with a “cheat sheet” of Basic Linux Commands. This list includes a bunch of different commands that are useful to know when working with Linux.

Managing files and directories

• cd directory: changes the current working directory to the specified one
• pwd: prints the current working directory
• ls: lists the contents of the current directory
• ls directory: lists the contents of the received directory
• ls -l: lists the additional information for the contents of the directory
• ls -a: lists all files, including those hidden
• ls -la: applies both the -l and the -a flags
• mkdir directory: creates the directory with the received name
• rmdir directory: deletes the directory with the received name (if empty)
• **rm **file: deletes the file, we can either go one-by-one or we delete them all together using the *
• cp old_name new_name: copies old_name into new_name
• mv old_name new_name: moves old_name into new_name
• touch file_name: creates an empty file or updates the modified time if it exists
• chmod modifiers files: changes the permissions for the files according to the provided modifiers; we’ve seen +x to make the file executable
• chown user files: changes the owner of the files to the given user
• chgrp group files: changes the group of the files to the given group
