mv command question

mjdbouk · #1 (**permalink**) 06-05-2008

Hello,

i am trying to rename a file X to file Y on different location .

lets say the mv command started but for some reason system crashed while it did not finish.

will file Y be created physically with lets say half the records of what was in file X???

thanks in advance.

From the AIX mv man page:

Quote:

... the mv command copies the file to the target and deletes the original file.

So it should delete the source only when the copying was successful. You can test it by moving a large file maybe and while it is copying, you send the mv a kill -9, which should bash it very hard, ie. like a crash.

However, yes, it's quite possible that the destination exists but only has a fraction of the complete file. Examine the file's size and maybe md5sum to be on the safe side.
