What attribute for a locked file?

Running Leopard on a Mac Pro. Photoshop won't start--claims that a file
is locked. Well it isn't the PS app, and it isn't an image file that I'm
trying to open. So?

I'd like to search down the applications file directory, and see if
there is a file that got locked that PS is trying to open. Some aux file
of some sort.

So how? I could use 'find' in a terminal window, but nothing in the man
page indicates what attribute a locked file has. AFAIK, this is
Mac-specific, and not standard Unix semantics. (But then, my Unix
knowledge is rather out-of-date.) I also have a Python program that
lists files recursively that I could modify, if there were some known
attribute for a locked file.

Any help appreciated. Hope I haven't missed something obvious. Thx.

BTW, this all started after I tried to do a permissions repair, using
the Leopard disk utility, on the volume containing the PS app. I should
have left it alone!

You would want /usr/bin/GetFileInfo

It may also help to run opensnoop while you launch Photoshop (actually,
your Python script might want to run it (with -x argument?) and check
the locked bit of each file it reports)
