Deleting files linux command

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.

How to Delete Files and Folders in Linux

Linux command line fundamentals are absolutely essential for every future system administrator and advanced Linux user. Today we’ll cover another basic function – deleting files and directories in Linux using the command line.

The rmdir Command

The command used to delete empty directories in Linux is rmdir.

The basic syntax of this command is easy to grasp. here’s an example:

• rmdir is the command
• [option] is an optional modifier that changes the way the command behaves
• DirectoryName is the directory you want removed

If no option is provided, rmdir simply deletes the directory whose name is provided as the destination. Before using this command, you’ll have to log into your VPS server using SSH. Here’s an article to help you out.

Remove Folders in Linux Using the rmdir Command

Before using the rmdir command we suggest you check the files present in a directory with the ls command. In our case, we have a directory named Dir1.

This command will delete the empty directory named Dir1. Simple enough, right?

You can also delete multiple directories by separating their names by spaces. For instance:

After executing this command, the directories named Dir1, Dir2 and Dir3 will be deleted.

Let say we have a directory named Dir3. Dir3 has subdirectories and files inside of it. Now if we use following command:

We will receive an error like this:

As you may have guessed from the output, rmdir only works with empty directories.

The rmdir is a smart utility, and only allows you to delete empty directories as a built-in safeguard to prevent accidental loss of data. Remember it’s almost impossible to recover deleted data on any Linux distribution.

The -p option lets you delete the directory as well as its parent directories.

This above command will delete Dir3 and its parent directories Dir2 and Dir1.

The -v option outputs a diagnostic text for every directory processed. Using this option will output a confirmation listing all the directories that were deleted.

The rm Command

The rmdir command is great for safely removing unused and empty directories. If you want to remove files or directories containing files, you would have to use the rm command.

The basic syntax of this command is similar to rmdir:

Remove Files in Linux Using the rm Command

Use the rm command to remove the file named article.txt:

If we have a directory with the name Dir1 containing subdirectories and files we will have to attach the -r modifier. The command would look like this:

The -r option recursively removes directories and their content.

Another helpful option is -i. This will ask you to confirm the files that will be deleted individually. That way you can avoid any unpleasant mistakes.

You can also delete empty directories using -d option. The following command will delete an empty directory with name Dir1:

You can use a wildcard (*) and a regular expansions to match multiple files. For instance, the following command will delete all pdf files placed in the current directory.

You can use variation of all the commands listed above to delete files with other extensions like .txt, .doc, .odt, etc.

The -f option lets you forcefully delete everything placed in a directory. The command would look like this:

The above command will delete everything recursively and forcefully, residing under the Dir1 directory without prompting anything on the terminal.

You can also delete more than one directory at a time. The following command will delete three directories Dir1, Dir2 and Dir3 in a single command.

Congratulations, you successfully mastered all the basic functions of the rm and rmdir commands!

Wrap Up

In Linux deleting a single file by accident can lead to major issues. That’s why it’s essential to master the two main commands for file and directory removal – rm and rmdir. In this article we cover these two commands and the various options that can be used with them.

We hope you found this article useful! Remember, once you delete a file or directory from Linux, you can’t recover it, so be extra careful! Good luck.

Как удалить файлы и каталоги с помощью командной строки Linux

How to Remove Files and Directories Using Linux Command Line

В этом руководстве мы покажем Вам, как использовать rm , unlink и rmdir команды для удаления файлов и каталогов в Linux.

Как удалить файлы

Чтобы удалить (или удалить) файл в Linux из командной строки, используйте команду rm (удалить) или unlink команду.

Команда unlink позволяет удалить только один файл, при этом rm вы можете удалить несколько файлов одновременно.

Будьте особенно осторожны при удалении файлов или каталогов, потому что, как только файл удален, он не может быть легко восстановлен.

Чтобы удалить один файл, используйте команду rm or, unlink а затем имя файла:

Если файл защищен от записи, вам будет предложено подтвердить, как показано ниже. Чтобы удалить тип файла y и нажмите Enter . В противном случае, если файл не защищен от записи, он будет удален без запроса.

Чтобы удалить несколько файлов одновременно, используйте rm команду, за которой следуют имена файлов, разделенные пробелом.

Вы также можете использовать подстановочный знак ( * ) и обычные расширения для сопоставления нескольких файлов. Например, чтобы удалить все .pdf файлы в текущем каталоге, используйте следующую команду:

При использовании обычных расширений сначала перечислите файлы с помощью ls команды, чтобы вы могли видеть, какие файлы будут удалены перед выполнением rm команды.

Используйте опцию rm with -i для подтверждения каждого файла перед его удалением:

Чтобы удалить файлы без запроса, даже если файлы защищены от записи, передайте параметр -f (force) rm команде:

Вы также можете комбинировать rm варианты. Например, чтобы удалить все .txt файлы в текущем каталоге без запроса в подробном режиме, используйте следующую команду:

Как удалить каталоги (папки)

В Linux вы можете удалять / удалять каталоги с помощью rmdir и rm .

rmdir утилита командной строки для удаления пустых каталогов, в то время как rm вы можете рекурсивно удалять директории и их содержимое.

Чтобы удалить пустой каталог, используйте либо имя, rmdir либо rm -d имя каталога:

Чтобы удалить непустые каталоги и все файлы в них, используйте rm команду с параметром -r (рекурсивный):

Если каталог или файл в каталоге защищен от записи, вам будет предложено подтвердить удаление.

Чтобы удалить непустые каталоги и все файлы без запроса, используйте rm с -r (recursive) и -f параметрами:

Чтобы удалить несколько каталогов одновременно, используйте rm -r команду, за которой следуют имена каталогов, разделенные пробелом.

Как и в случае с файлами, вы также можете использовать подстановочный знак ( * ) и обычные расширения для соответствия нескольким каталогам.

Вывод

Теперь вы должны иметь хорошее представление о том , как использовать Linux rm , rmdir и unlink команды , и вы должны иметь возможность безопасно удалить файлы и папки из командной строки.

How to Remove Files and Directories in Linux Command Line [Beginner’s Tutorial]

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.

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.

3. Remove multiple files

To remove multiple files at once, you can provide all the filenames.

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.

It will ask for confirmation for each of the file. You can enter y to delete the file and n for skipping the deletion.

You just learned to delete files. Let’s see how to remove directory in Linux.

How to remove directories in Linux

There is a command called rmdir which is short for remove directory. However, this rmdir command can only be used for deleting empty directories.

If you try to delete a non-empty directory with rmdir, you’ll see an error message:

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.

2. Remove directory with content

To remove directory with contents, you can use the recursive option with rm command.

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.

4. Remove multiple directories

You can also delete multiple directories at once with rm command.

Summary

Here’s a summary of the rm command and its usage for a quick reference.

Purpose	Command
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
