Hi all...

slightly new to this, need to accomplish something simple.

I have 12 jpgs in a directory called "copy"
I need a script to rename "news1.jpg" to "news2.jpg"
and so on through the list.
So 1 becomes 2, 2 becmes 3, 3 becomes 4 etc...

The path from perl script to jpgs is simply:
.../copy/news1.jpg

All and any help much appreciated.
Tony

perldoc -f opendir
perldoc -f readdir
s/(\d+)/$1 +1/e;
perldoc -f rename

That should give you a start.

perldoc -f opendir
perldoc -f readdir
s/(\d+)/$1 +1/e;
perldoc -f rename

Mightn't you also need
perldoc -f sort
So that you rename foo3 to foo4 before renaming foo2 to foo3?

Hi all...

Hi: pick your subject with more care.

I have 12 jpgs in a directory called "copy"
I need a script to rename "news1.jpg" to "news2.jpg"
and so on through the list.

I would fire up my editor, open a dos box, get the list of file names,
paste them in the editor, record a macro, and let that one do the trick.

You could move them to another directory at the same time.

The list isn't complete. "perldoc -f -f" would be another candidate,
to eliminate not-plain files. I wanted to give the OP enough material
to come up with an attempt at a solution. Then we could discuss that.

Thanks for all your help.
In the end (owing to time pressure) I did it in Flash
and let a simple .txt file cope with being rewritten to hold
the variable names then pump them back into flash with new
instance names.

I know this would hae been quicker in perl though...
Must read the books...

Best wishes

[ renaming 12 files ]

Amazing, in the editor I use (TextPad) I could do this in probably 2
minutes [1] for 12 files.
