How to Remove Files and Directories in Linux: rm, shred, rmdir

The command line does not have a Trash folder. When you delete a file from the terminal, it is gone immediately. There is no undo and no recovery confirmation by default.

This guide explains how to remove files and directories in Linux using rm, shred, unlink, and rmdir — and when to reach for each one.

How to Remove Files in Linux

The rm command is the standard tool for deleting files. To delete a single file:

bashrm filename

rm requires write permission on the parent directory, not just the file itself. If you lack that permission, the command fails with “Operation not permitted” regardless of the file’s own permissions.

Write-protected files trigger a confirmation prompt before deletion. To skip prompts entirely — including for write-protected files — use -f (force):

bashrm -f filename

To confirm each file interactively before deleting, use -i. This is the safer choice when working with wildcards:

bashrm -i *.pdf

Wildcard safety. Before running rm *.ext, preview the matches with ls first:

bashls *.pdf      # confirm what would be deletedrm *.pdf      # then remove

Combine options for verbose output:

bashrm -fv *.txt    # force delete + print each filename removed

Filenames starting with - are misread as flags. Prefix with -- or ./ to work around it:

bashrm -- -filenamerm ./-filename

unlink removes a single file by calling the kernel’s unlink(2) system call directly. It accepts no flags, no wildcards, and only one filename at a time:

bashunlink filename

Use unlink when you want minimal interface and no accidental multi-file behavior. Use rm for everything else.

Secure Deletion with shred and When to Use It

Standard rm does not erase the actual data on disk. It removes the inode reference — the metadata pointer to the file — and marks the underlying data blocks as free for reuse. The file’s content stays on disk until something else writes over those blocks.

That means deleted files can often be recovered with forensic tools if the disk blocks have not been overwritten yet.

shred -u closes this gap:

bashshred -u filename

It runs in three steps: overwrite the file’s data blocks (multiple passes by default), truncate the file to zero bytes, then remove it. The overwrite step makes the original content unrecoverable.

bashshred -u filename1 filename2    # multiple files

Use shred when deleting sensitive data — credentials, private keys, confidential documents — or before decommissioning a drive. For routine file deletion, rm is sufficient.

How to Remove Directories with rmdir and rm

rmdir deletes empty directories only:

bashrmdir dirname

If the directory contains any files or subdirectories, rmdir fails with an error and leaves the directory untouched. This makes it the safe choice in scripts when you want to remove a directory only if it is truly empty.

rm -r recursively deletes a directory and everything inside it:

bashrm -r dirname

Write-protected files inside the directory will trigger prompts. To suppress all prompts:

bashrm -rf dirname

rm -rf is irreversible and will delete everything at the path with no confirmation. Never run it with /, ~, or a variable that might be empty or unset. Always double-check the path.

To delete multiple directories at once:

bashrm -r dirname1 dirname2 dirname3

To delete only the contents of a directory while keeping the directory itself:

bashrm -r dirname/*    # removes all contents recursively

Use rm for files, rm -r for directories, and rmdir when you want safe deletion of empty directories only. Add -i or preview with ls before using wildcards, and reach for shred -u only when the file’s content must not survive deletion. Leave a comment below if you run into any issues.
