I have a minor follow up. If I were in the folder when the command is executed from within the parent folder, for example:

Code:

>/bin/folderRename.sh .

then the file names get set with the period and the name of the parent folder is not applied.

Code:

if [${1} eq '.'] 
  then 
   DIR=$PWD
  else
   DIR=${1}
fi
PREF=$(basename "$DIR")
cd $DIR
for i in *; 
do 
        mv $i ${PREF}${i};
done

I get a complaint stating "[.: command not found". Looks like I cannot use the "." for comparison.

Please assist. Thanks again.
