How to delete a file in Linux? How to delete a directory in Linux? Let’s see how to do both of these tasks with one magical command called rm.
How to delete files in Linux
Let me show you various cases of removing files.
1. Delete a single file
If you want to remove a single file, simply use the rm command with the file name. You may need to add the path if the file is not in your current directory.
If the file is write protected i.e. you don’t have write permission to the file, you’ll be asked to confirm the deletion of the write-protected file.
rm: remove write-protected regular file 'file.txt'?
You can type yes or y and press enter key to confirm the deletion. Read this article to know more about Linux file permissions.
2. Force delete a file
If you want to remove files without any prompts (like the one you saw above), you can use the force removal option -f.
rm -f file.txt
3. Remove multiple files
To remove multiple files at once, you can provide all the filenames.
rm file1.txt file2.txt file3.txt
You can also use wildcard (*) and regex instead of providing all the files individually to the rm command. For example, if you want to remove all the files ending in .hpp in the current directory, you can use rm command in the following way:
4. Remove files interactively
Of course, removing all the matching files at once could be a risky business. This is why rm command has the interactive mode. You can use the interactive mode with the option -i.
rm -i *.txt
It will ask for confirmation for each of the file. You can enter y to delete the file and n for skipping the deletion.
rm: remove regular file 'file1.txt'? y rm: remove regular file 'file2.txt'? n
You just learned to delete files. Let’s see how to remove directory in Linux.
How to remove directories in Linux
If you try to delete a non-empty directory with rmdir, you’ll see an error message:
rmdir: failed to remove 'dir': Directory not empty
There is no rmdir force. You cannot force rmdir to delete non-empty directory.
This is why I am going to use the same rm command for deleting folders as well. Remembering rm command is a lot more useful than rmdir which in my opinion is not worth the trouble.
1. Remove an empty directory
To remove an empty directory, you can use the -d option. This is equivalent to the rmdir command and helps you ensure that the directory is empty before deleting it.
rm -d dir
2. Remove directory with content
To remove directory with contents, you can use the recursive option with rm command.
rm -r dir
This will delete all the contents of the directory including its sub-directories. If there are write-protected files and directories, you’ll be asked to confirm the deletion.
3. Force remove a directory and its content
If you want to avoid the confirmation prompt, you can force delete.
rm -rf dir
4. Remove multiple directories
You can also delete multiple directories at once with rm command.
rm -r dir1 dir2 dir3
Here’s a summary of the rm command and its usage for a quick reference.
|Delete a single file||rm filename|
|Delete multiple files||rm file1 file2 file3|
|Force remove files||rm -f file1 file2 file3|
|Remove files interactively||rm -i *.txt|
|Remove an empty directory||rm -d dir|
|Remove a directory with its contents||rm -r dir|
|Remove multiple directories||rm -r dir1 dir 2 dir3|
