If no parameters are specified, the rm command will prompt the user to confirm whether to delete the specified file or directory; 2. The rmdir command is used to delete empty directories. If the directory is not empty, the rmdir command will prompt the user that the directory is not empty and cannot be deleted; 3. The shred command is used to safely delete files or directories, etc.

Linux deletion commands mainly include the following types:

1. rm: Use the rm command to delete files or directories. When executing, you need to specify the file or directory to be deleted. If no parameters are specified, the rm command prompts the user to confirm whether to delete the specified file or directory.

Usage: rm [options] file or directory

Common options:

-f Or --force: Forcefully delete files or directories without prompting the user for confirmation.

-i or --interactive: Prompt user for confirmation before deleting a file or directory.

-r or --recursive: Recursive processing, delete all files and directories in the specified directory and its subdirectories.

-v or --verbose: Display details of the deletion process.

2. rmdir: The rmdir command is used to delete empty directories. If the directory is not empty, the rmdir command will prompt the user that the directory is not empty and cannot be deleted.

Usage: rmdir [options] Directory

Common options:

-p or --parents: Deletes a directory recursively, also deleting the parent directory of the specified directory.

3. shred: The shred command is used to safely delete files or directories. When deleting a file, the shred command will overwrite the file data multiple times to ensure that the data cannot be recovered.

Usage: shred [option] file or directory

Common options:

-u or --update: Only perform deletion if the file or directory exists.

-f or --force: Forcefully delete the file or directory without prompting the user for confirmation.

-n or --count: Specify the number of times to overwrite file data.

4. mv: The mv command is used to move files or directories, or rename files or directories. When moving a file or directory, if a file or directory with the same name already exists in the target path, the mv command will prompt the user whether to overwrite it.

Usage: mv [options] Source file or directory destination path

Common options:

-i or --interactive: Prompt user for confirmation when overwriting a file or directory on the target path.

-u or --update: Perform a move or rename operation only if the source file or directory is newer than the file or directory of the same name on the target path.

5. cp: The cp command is used to copy files or directories. When copying a file or directory, if a file or directory with the same name already exists in the target path, the cp command will prompt the user whether to overwrite it.

Usage: cp [options] Source file or directory destination path

Common options:

-i or --interactive: Prompt user for confirmation when overwriting a file or directory on the target path.

-u or --update: Perform the copy operation only if the source file or directory is newer than the file or directory of the same name on the destination path.

-r or --recursive: recursive processing, copy all files and directories in the specified directory and its subdirectories.

6. tar: The tar command is used to pack and unpack files. Through the tar command, multiple files or directories can be packaged into a compressed file for easy storage and transmission.

Usage: tar [options] [-czvf] Target file or directory

Common options:

-c or --create: Create a new compressed file.

-z or --gzip: Use the gzip algorithm for compression.

-v or --verbose: Display detailed information, used to display the file list during compression.

-f or --file: Specify the file name of the compressed file.

These commands are very useful in Linux systems, and mastering their usage will help you better manage files and directories. In actual operation, these commands can be used flexibly as needed to improve work efficiency.
