Linux delete file with file name

How To Delete File In Linux?

Deleting files in Linux can be sometimes tricky. We have a tool named rm which is the shortcut for the word remove. In this tutorial, we will look at how to remove or delete a file in Linux with different examples and ways.

rm Command Syntax

rm command syntax is the same as the most the Linux command. We can provide options before specifying the file and directories we cant to operate or delete.

• OPTINS states the behavior of the rm command as we will see below in detail.
• FILENAME is the file or directory name we want to delete or operate.

rm Command Help

rm command help information can be printed to the console with the —help command which is like below. Help information will provide some popular options and usages.

Delete Single File with rm Command

We will start with simple steps just deleting a single file. We will just specify the file name we want to delete. In order to remove the file successfully, we should have privileges to modify a file. For example, if we try to remove the file owned by root with a regular user we will get an error and would not delete the file. In this example, we will delete the file named foo.txt

Delete Multiple Files with rm Command

We have the ability to delete multiple files in a single rm command. We will just put file names we want to delete by separating them with space. In this example, we will delete file names foo.txt and bar.txt but we can add more if we need it.

Delete Files According To Their Extensions/Types with rm Command

Linux bahs provides the glob or asterisk in order to specify the files with a specific name or extension. We can use glob * in order to specify a specific extension like *.txt , *.pdf , *.tmp etc. We can use this extension or name specification in order to delete specific files. In this example, we will delete all *.deb extensions.

We can also specify names like deleting all files which name starts with pof like below.

Delete Files Recursively

rm command provides the ability to delete or remove files recursively. Recursive removal will check subdirectories for files to remove with the directories. We will remove the directory name ndiff with all sub-directories and files in this example. We will use -R option for the recursive operation.

Delete File with Prompt Before Every Removal

While removing files and directories we may need approval for each file to delete. In this case, we can use -i option which will prompt to accept or deny deletion of the given file.

Print Verbose Output About Delete Operation

While deleting files and directories we may want to see details of the removal operation. rm command provides a verbose option which will list information about each deletion of file or directory. We will use -v option for this.

Delete empty Directories or Folders with rmdir Command

In some cases, we need to delete empty folders. rm without options will not work in this case as we can see this in the following screenshot. We case use rmdir command to remove an empty directory or folder.

Read File Names From Text File For Delete or Removal

Another interesting use case for rm command is providing file or directory names from a list like a text file. We will use xargs command to-read the list and redirect to the rm command.

Delete File Names Starts with Dash —

Another interesting case is dash or — problem where file or directory names starting with dash . As we know Linux commands options are specified with dash . So how can rm recognize file name from option? We will use — or double dash were to specify the file or directory name start. For example we have a file named -file.txt and we want to remove. We will use the following command. As we can see the file name is specified after double dash. Options are specified before the double dash.

Delete Files By Reading Their Names From A File/List

In some cases, we may need to read a list that contains the file names we want to delete. This is generally a simple text file where each file name with their path is specified line by line. We can use xargs command to redirect the list contents to the rm command which will delete them one by one. In this example, we will read the list file names file-list.txt .

Delete Files By Finding them with find Command

find is a very useful command which is used to find files and folders. find command also provides some options like running commands on the search results. We can also remove or delete files found by the find command. In this example, we will delete files that are older than 3 days.

UNIX: Remove A File With A Name Starting With – (dash) Character

I am a new Unix shell user at my university shell server. Accidentally, I had created a file called -foo . Now, how do I remove a file with a name starting with ‘ — ‘ under UNIX-like or Linux operating system?

You can use standard UNIX/Linux rm command. All you have to do is instruct the rm command not to follow end of command line flags by passing double dash — option before -foo file name.

Syntax: rm command to remove a file

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 to delete the specified files and directories:

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

When rm command used just with the file names, rm deletes all given files without confirmation by the user.

Warning : Be careful with filenames as Unix and Linux, by default, won’t prompt for confirmation before deleting files. Always keep verified backups of all critical files and data.

Unix Remove or delete a file example

Say you have a file named abc.txt and you want to remove it:
$ rm abc.txt

Linux delete multiple files

Delete three files named foo.mp4, bar.doc, and demo.txt, run:

Linux recursively delete all files

Remove all files and sub-directories from a directory (say deltree like command from MS-DOS world), enter:
$ rm -rf mydir

Linux delete a file and prompt before every removal

To request confirmation before attempting to remove each file pass the -i option to the rm command:
$ rm -i filename
Sample outputs:

Gif 01: rm command demo

Force rm command to explain what is being done with file

Pass the -v option as follows:
$ rm -v moiz.list.txt bios-updates.doc
removed ‘moiz.list.txt’
removed ‘bios-updates.doc’

How to delete empty directories

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

How to 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

How do I delete a file named -foo.txt or a directory named -bar?

To delete a file called -foo.txt :
rm — -foo.txt
OR
rm — ./-foo.txt
To delete a directory called -bar :
rm -r -f — -bar
The two — dashes tells rm command the end of the options and rest of the part is nothing but a file or directory name begins with a dash.

Never run rm -rf / as an administrator or normal UNIX / 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 Unix 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.

Conclusion

You learned how to delete files on Linux and Unix-like operating systems. Here are all important options for GNU rm command (read man page here)

Remove files command summary

Option	Description
-f	Ignore nonexistent files and arguments, never prompt
-i	Prompt before every file removal
-I	Prompt once before removing more than three files, or when removing recursively; less intrusive than -i, while still giving protection against most mistakes —interactive[=WHEN] prompt according to WHEN: never, once (-I), or always (-i); without WHEN, prompt always
—one-file-system	when removing a hierarchy recursively, skip any directory that is on a file system different from that of the corresponding command line argument
—no-preserve-root	do not treat ‘/’ specially
—preserve-root[=all]	do not remove ‘/’ (default); with ‘all’, reject any command line argument on a separate device from its parent
-r	remove directories and their contents recursively
-R	same as above
-d	rmove empty directories
-v	Explain what is being done

How to delete all files with filenames containing spaces on Linux? [duplicate]

cannot delete my own question, overwrite instead

2 Answers 2

Alright, let’s do this progressively.

And let’s presume that you really do want to look in subdirectories as well, even though that’s only implied in your question.

As a first pass, this is just a simple exercise in passing a wildcard to the find command, remembering to quote it of course, and executing the rm command for every file found:

But of course that’s dreadfully inefficient. It starts up a whole rm process for each individual file. So while we could take a short detour through \+ that’s not where we are going to end up, so let’s take the shorter route and bring in xargs to batch up the filenames into groups:

But that has two security holes. First, if any filename found happens to begin with a minus sign rm will treat it as a command-line option rather than a filename, and generate an error. (The -exec rm <> version also has this problem.) Second, filenames containing whitespace will not be handled properly by xargs , as you’ve noticed. So a further iteration is to make this a little more bulletproof:

And, of course, there are the interactive features of rm that you probably don’t want:

The -print0 and -0 options are not standard, but the GNU find and xargs , as well as the FreeBSD find and xargs , understand them. However, even this is improvable. We don’t need to spawn any extra processes at all. The GNU and FreeBSD find s can both invoke the unlink(2) system call directly:

As a last preventative measure to stop you doing more than you intended in certain circumstances, remember that the filesystem can contain more than just regular files:
