Having a huge amount of files, I had to change the files in uppercase.
Just a quick command line/script that at change in uppercase the file’s name and extension based on the extension given.
echo “Which extensions type of files would you like to change in uppercase?”
for i in *.$file
j=`echo $i | tr ‘[a-z]’ ‘[A-Z]’`
mv $i $j
echo “This file has been renamed:”
echo $i to $j
