If you are working on Linux, then you may need to remove certain files and directories based on a set of predetermined requirements. Linux provides several tools to remove files and directories. Among them, the rm and rmdir are the most widely used commands to remove files and directories on Linux, macOS, and Unix-based operating systems.
In this post, we will show you how to remove files and directories in Linux.
Remove a Single File
The rm command allows you to remove one or more files in a one-liner command.
To remove a single file, run the following command:
rm file1.txt
The above command will delete a file without prompting you to confirm file deletion.
If you want to make the rm command always prompt before deleting a file, use the -i flag:
rm -i file1.txt
You can use the -v flag to display what the rm command is actually doing:
rm -v file1.txt
If you want to remove a write-protected file without prompting for confirmation, use the -f flag:
rm -f file1.txt
