Copying and Moving Files

cp

-a	archive files
-f	force copy by removing the destination file if needed
-i	interactive - ask before overwrite
-l	link files instead of copy
-L	follow symbolic links
-n	no file overwrite
-R	recursive copy (including hidden files)
-u	update - copy when the source is newer than the destination
-v	verbose - print informative messages

rm

rm is used to remove (delete) files. For more information about the available options, see rm command.

rm [options] <filename>
rm -rf <directory/filename> # force delete files/directories recursively

警告

If the target directory is not empty, this command won't work. In this case, use cp and rm as described in the section below.

mv [options] source destination

Command options:

0ption	Description
-f	force move by overwriting destination file without prompt
-i	interactive prompt before overwrite
-u	update - move when the source is newer than the destination
-v	verbose - print source and destination files

Using rm and cp rather than mv

To move a file to a directory that is not empty (i.e., move files/directory and delete the original one), in which case mv won't work, use the cp command together with rm:

cp -r ./backup/* ./backupArchives && rm -R ./backup/*

• The first command: copies the directory ./backup/* and the files contained to ./backupArchives.

• The second command: deletes the original directory ./backup/*.
