Shell Programming and Scripting

I have a file, let's say 1.jpg, and I have a text file that contains a list of filenames I would like to duplicate 1.jpg as (i.e., 2.jpg, 3.jpg, 4.jpg, etc.). The filenames that I want to create are all on separate lines, one per line.

I'm sure there's a simple solution, but I'm not claiming to be a programmer by any means.

If anybody could help me out I would greatly appreciate it.

Thanks!

if names are in file called "filenames":

for i in `cat filenames`; do cp 1.jpg $i; done

why exactly do you need a cat?

Thank you mglenney! That worked like a charm.

Because most of the time I can figure out how to do something I just don't necessarily know the best way to do it. I know it could also be done like this:

while read i; do cp 1.jpg $i; done < filenames

But I don't know if that's any better. I'm always looking for better (quicker, best practice, etc.) ways of doing things so if you have one I'd appreciate the lesson.

checkout the posted link.

Ok. I was looking at the "Useless use of cat" section at the top but I think you're referring to the section about using backticks. According to that my second example above would be the best route.

Reading that made me think of another question. I created a new thread for it. Maybe you can help me there.

Thanks,

MG
