Wink File naming using awk


Hi,

I am a complete newbie.

how do I use awk to rename 950 files in a folder from s-xxx.txt to S-xxx.txt and from SU-xxx.txt to Su-xxx.txt where xx are numbers from 1 to 950.

Thanks

Hi and welcome to LinuxQuestions!

To rename files the rename command is more straightforward. Depending on your Linux distribution you may have one of two different flavours of the rename command. What Linux OS are you running on?

Or do you have some reasons to use awk instead?

Renaming file names

Hi,

I am not in linux at this moment as I am on my PC at home and going into linux from EXCEED. I have 950 files to rename. 560 are in one directory and the rest in another directory.

Thanks!

Why use awk?
Code:
for i in s-[0-9][0-9][0-9].txt do
   n= ${i:1}
   mv $i S${n}
done
for i in SU-[0-9][0-9][0-9].txt do
   n= ${i:2}
   mv $i Su${n}
done

You don't have to use awk...very first hit in Google for "rename multiple files in Linux":

The rename command will do what you need.

can use ${i#*s} and ${#*U} to replace the both n
