CP Replication Command

The CP command copies files from one location to another. If the destination file exists, the file will be overwritten; If the destination directory exists, the file is copied to the directory (the directory is not replicated).

CP [command Switch] ... SOURCE DEST

CP [OPTIONS] ... SOURCE ... DIRECTORY

CP [Options]...–target-directory=directory SOURCE ...

Command switch:

-a equals-dpr.
–backup[=control]

MV Move Command

MV command is the abbreviation for move. Use it to move/rename files from one directory to one directory. MV command is different from the CP command, the MV command is complete from the source to move the file and move the file to the specified directory, where the CP command just copy the contents of the file from one file to another file.

Grammar:

Grammar is

MV [-F] [-i] original name new name

Command switch:

-F Do not prompt before overwriting (equivalent to equivalent –reply=yes). Mv-f will move the file (multiple files) without prompting, even if it will overwrite the existing target file.
-I. Make a note before making a copy of another file

Example:

To rename/move a file:

MV File1.txt File2.txt

This command renames the File1.txt file with the name File2.txt.

To move a directory

Move a directory

MV Hscripts TMP

In the above command, if the TMP directory already exists, the MV command moves all files, directories, and subdirectories in the Hscripts folder/directory to the TMP directory. If there is no TMP directory, it renames the Hscripts directory as the TMP directory.

Move multiple files/More ask price to another directory

MV File1.txt Tmp/file2.txt Newdir

This command moves the file1.txt file of the current directory and the File2.txt file of the TMP folder/directory to the Newdir directory.

RM Delete command

RM Linux commands are used to remove/delete files in the directory.

Grammar is

RM [command Switch ...] [File | directory]

Command switch:

-F Deletes all files under the directory without prompting the user.
-I. Interactive mode. With this option, the RM command prompts the user for confirmation before deleting any files.
-R (or)-R The directory in the recursive delete parameter table and its subdirectories. The directory will be emptied and deleted. The user is usually prompted when deleting a write-protected file contained in a directory.

RM file1.txt

To delete a directory tree:

Rm-ir tmp

Here the RM command recursively deletes the contents of all subdirectories under the TMP directory, which prompts you for deletion of each file, and then deletes the TMP directory itself.
