If you’re a Linux user, you know how to delete files and directories. But what if you want to delete files and directories in the Terminal? There are a few ways to do this. The first way is to use the command “rm”. This will delete all the files and directories in the current directory. The second way is to use the command “md”. This will create a new directory for each file and directory that is deleted. The third way is to use the command “xcopy”. This will copy all of the files and directories in the current directory into a new directory.
It is important to note that files and directories deleted using rm and rmdir do not get moved to the Trash. They are immediately removed from your computer. If you accidentally delete files using these commands, the only way you’ll be able to restore them is from a backup.
How to Remove Files with rm
The simplest case is deleting a single file in the current directory. Type the rm command, a space, and then the name of the file you want to delete.
If the file is not in the current working directory, provide a path to the file’s location.
You can pass more than one filename to rm. Doing so deletes all of the specified files.
Wildcards can be used to select groups of files to be deleted. The * represents multiple characters and the ? represents a single character. This command would delete all of the png image files in the current working directory.
This command would delete all files that have a single character extension. For example, this would delete File.1 and File.2, but not File.12.
If a file is write-protected you will be prompted before the file is deleted. You must respond with y or n and press “Enter.”
To reduce the risk of using rm with wildcards use the -i (interactive) option. This requires you to confirm the deletion of each file.
The -f (force) option is the opposite of interactive. It does not prompt for confirmation even if files are write-protected.
How to Remove Directories with rm
To remove an empty directory, use the -d (directory) option. You can use wildcards (* and ?) in directory names just as you can with filenames.
Providing more than one directory name deletes all of the specified empty directories.
To delete directories that are not empty, use the -r (recursive) option. To be clear, this removes the directories and all files and sub-directories contained within them.
If a directory or a file is write-protected, you will be prompted to confirm the deletion. To delete directories that are not empty and to suppress these prompts, use the -r (recursive) and -f (force) options together.
Care is required here. Making a mistake with the rm -rf command could cause data loss or system malfunction. It’s dangerous, and caution is the best policy. To gain an understanding of the directory structure and the files that will be deleted by the rm -rf command, use the tree command.
Use apt-get to install this package onto your system if you’re using Ubuntu or another Debian-based distribution. On other Linux distributions, use your Linux distribution’s package management tool instead.
Running the tree command produces a simple to understand diagram of the directory structure and files beneath the directory from which it is run.
You can also supply a path to the tree command to cause it to start the tree from another directory in the file system.
The rm command also has –one-file-system, –no-preserve-root, –preserve-root options, but those are only recommended for advanced users. If you get something wrong, you could accidentally delete all your system files. Consult the command’s manual page for more information.
How to Remove Directories with rmdir
There is another command, called rmdir, that you can use to delete directories. The difference between rm and rmdir is that rmdir can only delete directories that are empty. It will never delete files.
The simplest case is deleting a single empty directory. As with rm, you can pass multiple directory names to rmdir , or a path to a directory.
Delete a single directory in the current directory by passing its name to rmdir :
Delete multiple directories by passing a list of names to rmdir :
Delete a directory not in the current directory by specifying the full path to that directory:
If you try to delete a folder that is not empty, rmdir will give you an error message. In the following example rmdir successfully, and silently, deletes the clients directory but it refuses to delete the projects directory because it contains files. The projects directory is left exactly as it was and the files in it are untouched.
When rmdir gives a “Directory not empty” error, it stops processing the directories that were passed to it on the command line. If you’ve asked it to delete four directories and the first one had files in it, rmdir would give you the error message and do nothing more. You can force it to ignore these errors with the –ignore-fail-on-non-empty option so that other directories are processed.
In the following example two folders have been passed to rmdir, these are work/reports and work/quotes . The –ignore-fail-on-non-empty option has been included in the command. The work/reports folder has files in it, so rmdir cannot delete it. The –ignore-fail-on-non-empty option forces rmdir to ignore the error and move on to the next folder it needs to process, which is work/quotes. This is an empty folder, and rmdir deletes it.
This was the command used.
You can use the -p (parents) option to delete a directory and to delete its parent directories too. This trick works because rmdir starts with the target directory and then back-steps to the parent. That directory should now be empty, so it can be deleted by rmdir, and the process repeats stepping back up the path that was provided to rmdir.
In the following example the command that is passed to rmdir is:
Both the invoices and the work directories are deleted, as requested.
Whether you’re using Bash or any other shell, Linux provides flexible and powerful commands for you to delete directories and files straight from the terminal command line. Some people prefer to have a workflow that revolves around the terminal. Others may have no choice in the matter. They may be working on servers without a GUI installed or on a remote session onto a headless system such as a Raspberry Pi. These commands are perfect for that group of people.
But whatever type of workflow you prefer, these commands lend themselves very well to being included in shell scripts. If a script is triggered by a cron job, it can help automate routine housekeeping tasks such as purging unwanted log files. If you investigate that use case, remember the power of these commands, test everything carefully, and always maintain a recent backup.
