Important Linux Command

1) ls: The ls command is used to list files. "ls" on its own lists all files in the current directory except for hidden files

2) cd: change directory

The cd command allows you to move between directories. The cd command takes an argument, usually the name of the folder you want to move to, so the full command is cd your-directory.

3) pwd : Present Working Directory

The pwd command writes to standard output the full path name of your current directory (from the root directory). All directories are separated by a / (slash).
