UNIX for Dummies Questions & Answers

Hi All,

I've looked through the forum and haven't quite found what I'm looking to do.

We're migrating our systems from a midrange to HP-UX, and I'm quite new to UNIX so I'm hoping that I can get pointed in the right direction.

What I'm looking to do is save generations of files for recovery backup by tech support.

sample Format: ArcSave "filename" "count"

So what this would do is take the filename and add a counter to the end, and delete any file >= "count".

i.e.

Directory holds: subfil.sf, subfil.0001.sf, subfil.0002.sf, subfil.0003.sf, subfil.0004.sf, subfil.0005.sf

Run: ArcSave subfil.sf 4

Results:

Code:

- delete: subfil.0004.sf, subfil.0005.sf (anything >= 0004)
- rename: subfil.0003.sf to subfil.0004.sf
- rename: subfil.0002.sf to subfil.0003.sf
- rename: subfil.0001.sf to subfil.0002.sf
- rename: subfil.sf to subfil.0001.sf

If a file in the sequence didn't exist we would continue to the next file.

ie: subfil.0002.sf was missing
Results:

Code:

- delete: subfil.0004.sf, subfil.0005.sf
- rename: subfil.0003.sf to subfil.0004.sf
- rename: subfil.0001.sf to subfil.0002.sf
- rename: subfil.sf to subfil.0001.sf

I want to do a lot of other things as well, but I need a push in the right direction to get started.

Thanks, in advance, for all your help!
