Copy or Rename files *.JPG as *.jpg
| Posted by hbhb, 09-12-2010, 12:14 PM |
| I have hundreds of files with a .JPG extension on a directory.
I wanted to mass-copy or rename it as .jpg (small case), without overwriting existing file (if file exist)
For example:
abc.JPG -> abc.jpg (Fail: file exist)
abc.jpg
xyz.JPG -> xyz.jpg (Success)
Anyone can help? I try to search for the right command or script to do that but to no avail..

| I hope you are using a *NIX based machine.
Here you go.
for i in $(ls -1 *.JPG)
do
pre=$(echo $i | cut -d "." -f1)
cp -v $i ${pre}.jpg
done
Please run it on bash.

| In that case, you have to use
cp -f
it will do the trick.

| Supposely I do not want it to overwrite file. Default answer should be a 'NO'
-f sounds like 'force' to 'YES' ?
