Files can be removed or deleted by using different commands in Linux. The removal of the file deletes related file system information from the file system table. While deleting a file there are different ways like prompt deletion, display verbose output, etc.
Delete/Remove File with rm Command
rm command is a defacto command to delete and remove files in Linux and Unix operating systems. The rm command syntax is like below.
- FILE is the file name we want to delete.
In the following example, we remove the file named “main.txt” file.
$ rm main.txt
Delete/Remove File with unlink Command
Another less known command to delete or remove a file is the
unlink . It simply removes the inode descriptor and data on the file system. The unlink command syntax is like below.
- FILE is the file name we want to remove.
In the following example we remove the file named “main.txt”.
$ unlink main.txt
Delete/Remove File Forcibly
In some cases, the file we want to remove can be read-only, or some restrictions to remove in a regular way. We can remove the file forcibly by using the
$ rm -f main.txt
Delete/Remove File Interactively
By default, the rm command deletes the provided file. But we can make things more interactive by using the
-i option. This option request confirmation for the deletion of the specified file.
$ rm -i main.txt
Delete/Remove Multiple Files
The rm command can be also used to remove multiple files. Just put file names after the rm command and options if exist. In the following example, we remove files named “main.txt”,”cities.txt”,”users.txt”.
$ rm main.txt cities.txt users.txt
Delete/Remove Files with Specific Extension
The rm command can be also used to remove files with specific extensions. In the following example, we delete all files with
$ rm *.txt
Alternatively, we can provide multiple extensions to remove.
$ rm *.txt *.db
Delete/Remove Files Verbosely
By default, the rm command does not display any output unless there is not an error. We can print verbose output about the successful removal of the files. The
-v option is used to verbose deletion.
$ rm -v *.txt
