MV'd a file, now it's disappeared...

I'm doing an assignment for a Unix course at school.

I attempted to rename one of the shell programming questions from home to Q1 by typing:

mv home Q1

It returned a message saying

mv: cannot access home

And now there's no home or Q1 in the directory. Please help!

What happened to this? How did you resolve this? I am facing the same issue.

Please Help.

How much time a big file takes to rename?

At what level was "home" originally? (the pathname)

But What would make a file disappear?

Hard to say without knowing your syntax. Are you running CDE by chance? Check your trash? And how full is your disk?

No CDE.

It was a plain command

mv oldfile newfile:

Would still like to know how full your HDD is.
I'm running HP-UX 11.0 using the CDE (Common Desktop Environment) on an HP b2600 Workstation.
What are you running and on what?

It sits at 15% used. Space is no issue.
Running on AIX

Have you tried to duplicate the issue on an innocuous file?
