You've learned to use the Touch command to create a file, and to use the mkdir command to create a directory Tigger.
Now, you need to learn how to delete files and directories. Using the RM command to delete files and directories is a straightforward process. Please refer to RM Specification page for details. Options for deleting files and directories include:
»-i-interaction. Prompt you to confirm the deletion. This option will help you avoid accidentally deleting files.
»-f-coercion. Instead of interactive mode, delete files without prompting. Unless you know what you're doing, it's not always advisable to use this option.
»-v-details. Displays the progress of the file deletion.
»-r-recursion. A directory and all of its files and subdirectories will be deleted.
To delete a file piglet.txt using the RM command, type:
RM piglet.txt
Warning
Once the file or directory is deleted using the RM command, it is gone forever.
Using the-I option will give you another chance to decide if you really want to delete the file.
Rm-i Piglet.txt
RM: Do you want to delete the general file ' Piglet.txt '?
You can also use the wildcard "*" to delete files, but you have to be careful as it is easy to delete files that you do not want to delete.
To use wildcards to delete files, you can type:
RM pig*
The above command deletes all files in the directory that are pig letters.
You can also use the RM command to delete multiple files. For example:
RM Piglet.txt Sneakers.txt
You can use RmDir to delete a directory (such as: RmDir foo), but the directory must be an empty directory. To remove a directory using RM, you must specify the-r option.
For example, if you want to delete a directory Tigger recursively, you can type:
Rm-r Tigger
If you want to combine options, such as forcing a recursive deletion, you can type:
RM-RF Tigger
Another command to delete a directory that is more secure than using RM is the RMDIR command. This command does not allow you to use recursive deletion, so you cannot delete the directory containing the files.
Warning
The RM command can remove your entire file system! If you log in as root, then type this simple command: RM-RF/, you're in a lot of trouble; This command will recursively delete everything on your system.
Read RmDir's manual page (man rmdir) For more information on this command
