How To Empty Directory In Linux and Unix

1. rm command – Delete one or more files or directories.
2. find command – Find and delete all files from a specific directory.

Linux Empty Directory Using the rm Command

First, consider the following directory structure displayed using the tree command

	/tmp/
	|
	|------foo/
		|---file1
		|---file2
		|---file3

To delete all files from /tmp/foo/ directory (i.e. empty /tmp/foo/ directory), enter:
$ cd /tmp/foo/
$ rm *
OR
$ rm /tmp/foo/*

Delete All Files Using the Find Command

Consider the following directory structure:

	/tmp/
	|
	|------bar/
		|	
		|---file1.txt
		|---file2.txt
		|
		|---subdir1/
		|	|---file1.doc
		|	|---file2.doc
		|
		|---subdir2/
			|---image1.jpg
			|---image2.png

To delete all files from /tmp/bar/ directory (including all files from sub-directories such as /tmp/bar/dir1), enter:
$ cd /tmp/bar/
$ find . -type f -delete
OR
$ find /tmp/bar/ -type f -delete
The above find command will delete all files from /tmp/bar/ directory. It will not delete any sub-directories. To remove both files and directories, try:
find /path/to/target/dir/ -delete
The find commands options are as follows:

• -type f : Delete on files only.
• -type d : Remove folders only.
• -delete : Delete all files from given directory name.

How to remove a full directory and all files in Linux

To remove a directory that contains other files or sub-directories, use the following rm command command. In the example, I am going to empty directory named “docs” using the rm -rf command as follows:
rm -rf /tmp/docs/*
Get verbose outputs:
rm -rfv /tmp/docs/*

The rm command options are as follows:

• -r : Delete directories and their contents recursively on Linux or Unix-like systems.
• -f : Forceful removal. In other words, ignore nonexistent files and delete whatever found.
• -v : Verbose outputs. For example, explain what is being done on screen.

Conclusion

You learned how to use the rm and find command to delete all files and sub-directories on Linux/macOS/*BSD and Unix-like systems. In other words, this is useful to empty folders on Linux. For more information see rm command help page here.
