Command Options

Options can be used to modify the behavior of shell commands. Shell command options are commonly represented by a single letter preceded by a -. For example, -l, -a, and -d could all be options that follow a shell command.

List contents in a directory

The ls shell command is used to list the contents in a directory.

cp shell command

The cp shell command is used to copy files or directories. The first argument is the source file and the second argument is the destination directory. If the target file name already exists, it will be overwritten. It can be used to copy more than one file at a time.

Copy Files and Directories

The cp command is used to copy files or directories.

The basic argument structure is cp source destination, where the source is the file or directory to copy to the destination file or directory.

mv shell command

Files can be moved using the mv shell command.

Delete files and directories

The rm shell command is used to delete files and directories. The -r flag deletes a directory and all of its files and directories (rm -r).
