Many time you may need to change the file or folder name case, for example lower to upper, upper to lower or toggle the case. I am giving you to the best solution to change the folder name case. We need to create a command for easy access. First of all create a script in “/usr/local/bin” folder and give it the execute permission, so any user can access this function as a command. I named this script ucf (upper case file) but you can user your name that you can easily remember and identify.
Note: You need super user privilege.
Create a script and put this script named “ucf” in /usr/local/bin and type “chmod a+x ucf”.

$ sudo vi /user/local/bin/ucf

#!/bin/sh
# uppercase any filenames with lowercase chars
for file in $*
do
if [ -f $file ]
then
  ucfile=`echo $file | tr '[:lower:]' '[:upper:]'`
  if [ $file != $ucfile ]
  then
    mv -i $file $ucfile
  fi    
fi
done

$ sudo chmod a+x /user/local/bin/ucf

OR
