Unix移动复制mv cp

mv

This command will move a file. You can use

mv

not only to change the directory location of a file, but also to rename files. Unlike the

cp

command,

mv

will not preserve the original file.
Note: As with the

cp

command, you should always use

-i

to make sure you do not overwrite an existing file.
To rename a file named

oldname

in the current directory to the new name

newname

, enter:
mv-ioldname newname To move a file named

hw1

from a subdirectory named

newhw

to another subdirectory named

oldhw

(both subdirectories of the current directory), enter:
mv-inewhw/hw1 oldhwIf, in this last operation, you also wanted to give the file a new name, such as

firsthw

, you would enter:
mv-inewhw/hw1 oldhw/firsthw

cp

This command copies a file, preserving the original and creating an identical copy. If you already have a file with the new name,

cp

will overwrite and destroy the duplicate. For this reason, it's safest to always add

-i

after the

cp

command, to force the system to ask for your approval before it destroys any files. The general syntax for

cp

is:
cp-ioldfile newfile To copy a file named

meeting1

in the directory

/home/dvader/notes

to your current directory, enter:
cp-i/home/dvader/notes/meeting1.The

.

(period) indicates the current directory as destination, and the

-i

ensures that if there is another file named

meeting1

in the current directory, you will not overwrite it by accident.
To copy a file named

oldfile

in the current directory to the new name

newfile

in the

mystuff

subdirectory of your home directory, enter:
cp-ioldfile ~/mystuff/newfile The

~

character (tilde) is interpreted as the path of your home directory.
Note: You must have permission to read a file in order to copy it.
