Use with caution. Skip to main content. Create, Copy, Rename, and Remove Unix Files and Directories This document lists commands for creating, copying, renaming and removing Unix files and directories. What Are Unix Files and Directories?

Naming Unix Files and Directories Each file and directory has a name. This is just a test. For example, to create an exact copy of the file called firstfile, you would type: cp firstfile secondfile This results in two files with different names, each containing the same information. If you create a different file called thirdfile and then type the following command: cp thirdfile firstfile you will find that the original contents of firstfile are gone, replaced by the contents of thirdfile.

Renaming a File Unix does not have a command specifically for renaming files. To change the name of a file, use the following command format where thirdfile and file3 are sample file names : mv thirdfile file3 This command results in the complete removal of thirdfile , but a new file called file3 contains the previous contents of thirdfile.

For example, if you have two files, fourthfile and secondfile, and you type the command mv fourthfile secondfile mv will remove the original contents of secondfile and replace them with the contents of fourthfile. Removing a File Use the rm command to remove a file.

For example, rm file3 deletes file3 and its contents. Creating a Directory Creating directories permits you to organize your files. The command mkdir project1 creates a directory called project1, where you can store files related to a particular project. Moving and Copying Files Into a Directory The mv and cp commands can be used to put files into a directory.

The command mv bibliography project1 will move the file bibliography into the directory project1. The command cp chapter1 project1 will place a copy of the file chapter1 in the directory project1 , but leave chapter1 intact in the current directory. Renaming a Directory You can also use the mv command to rename and move directories. When you type the command mv project1 project2 the directory called project1 will be given the new name project2 as long as a directory called project2 did not previously exist.

If directory project2 already existed before the mv command was issued, mv project1 project2 would move the directory project1 and its files into the directory project2. Copying a Directory You can use the cp command to create a duplicate copy of a directory and its contents. Removing a Directory Use the command rmdir to remove an empty directory.
