LowerIt non-recursive

## "LowerIt"
##
## Original code found here:  http://www.linuxjournal.com/content/convert-filenames-lowercase
## Modified by Maiya78 to change directory names, to work recursively, and to support unicode filenames on GNU systems.  I also copyedited the comments.  :3
##
## From the current directory, recursively convert to lower case all file and directory names
## Should ask for verification before overwriting an existing file.

## Clean up aliases
unset pwd && unset export && unset cd && unset echo && unset ls && unset
## Make sure we're in the right directory
export strDir=$(pwd)
cd $strDir
echo "Entering current directory:  "$strDir
## Need to make a loop or something here that repeats this for every subdirectory ad nauseum

## Show the user what's in the current directory pre-edit
echo "
Current directory before edit:  " && ls -a
## Start the editing loop
for strItem in $(ls -a)
do
## Save the computer some breath on . and ..
#    if [[ $strItem != '.' || '..' ]]; then
#        continue
#    fi
## Set a variable equal to the lowercased vesion of the original filename
    strLowerCasedItem=$(echo $strItem | sed 's/[[:upper:]]*/\L&/')
## If this variable is the same as the original, then the original was already lowercased, so we skip it.
    if [[ $strLowerCasedItem != $strItem ]]; then
        mv -i $(echo $strDir'/'$strItem) $(echo $strDir'/'$strLowerCasedItem)
    fi
done
## Show the user what's in the current directory post-edit
echo "
Current directory after edit:  " && ls -a
