How to delete a file


How do I delete a file under Linux  operating system?

To remove a file or directory in Linux use the rm command.

rm command syntax

rm (short for remove) is a Unix / Linux command which is used to delete files from a filesystem. Usually, on most filesystems, deleting a file requires write permission on the parent directory (and execute permission, in order to enter the directory in the first place). The syntax is as follows:

rm -f -r {file-name}


  • -f: Forcefully remove file
  • -r: Remove the contents of directories recursively

Remove or Delete a File

To remove a file called abc.txt type the following command:
$ rm abc.txt

To remove all files & subdirectories from a directory (MS-DOS deltree like command), enter:
$ rm -rf mydir

To remove empty directory use rmdir and not rm command:
$ rmdir mydirectory

Read a List of All Files To Delete From a Text File

The rm command is often used in conjunction with xargs to supply a list of files to delete. Create a file called file.txt:
$ cat file.txt
List of to delete:


Now delete all file listed in file.txt, enter:
$ xargs rm < file.txt

Never run rm -rf / as an administrator or normal Linux user

WARNING!  These examples will delete all files on your computer if executed.
$ rm -rf /
$ rm -rf *

rm -rf (variously, rm -rf /, rm -rf *, and others) is frequently used in jokes and anecdotes about Linux disasters. The rm -rf / variant of the command, if run by an administrator, would cause the contents of every writable mounted filesystem on the computer to be deleted. Do not try these commands.
