Here are the essential Linux commands that will help you navigate your Linux system. Display a List of Files With ls The ls command displays the names of the files and directories in the current working directory. A number of options are available that allow you to specify what details about the files should be shown. Change Directory With cd If you want to change the current working directory, use the cd command. For example, cd correspondence sets the current working directory to correspondence, if it exists. Copy a File With cp The cp command allows you to copy a file and give the copy a new name. It is always a good idea to make a copy of a file before you change it in case you want to go back to the previous version. Change a File Name With mv The mv command allows you to change the name of a file or move it to another directory or both. Files and whole directories can easily be moved even if they have a lot of content since it requires only changing how things are linked to each other. Create a New Directory With mkdir The mkdir command creates a new directory. Directories can be nested and are useful to organize large sets of files.
