Speed of mv vs. cp
Hi,
Is mv (move) command quicker than cp (copy command)?

I have large files and I want to know if mv actually copy the data to a new file then deletes the old or whether it just alters information the file system without physically moving data - Unfortuanately I don't have large files to test with...

Thanks.

Here is my thought ---->

"mv" is faster than "cp".

by doing "cp" we are creating another 'inode' structure for that file.

while doing "mv" ... we are just renaming tte filename attribute of the inode structure.

So, definitely "mv" is faster than "cp"

mv is faster than cp, unless you are moving to a new filesystem
