Create a script like this, name it lowercase.sh or something, and call it
with "lowercase file1 file2 dir1 dir2". I takes a list of files as
arguments (use * for all), and also works for directories.
So, "lowercase ." should convert all files and directories to lowercase.
Put the script into your $PATH, or precede it by its path, e.g. ./lowercase.
To test it before possible messing up (I just wrote this quickly) use
the -t option: lowercase -t /path/to/your/files
#!/bin/bash
# parse options (-t only)
while getopts "t" opt
do
case $opt in
t )
test=true
;;
* )
exit 1
esac
done
shift $(( OPTIND-1 ))
# loop over arguments
while (( $# ))
do
file=$1
if [[ -d $file ]]
then
# call myself
$0 ${test:+-t} "$file"/*
elif [[ -f $file ]]
then
# conversion to lowercase
dir=$( dirname "$file" )
base=$( basename "$file" )
lower=$( echo "$base" | tr '[:upper:]' '[:lower:]' )
newfile=${dir:+$dir/}$lower
[[ $file -ef $newfile ]] ||
${test:+echo} mv -v "$file" "$newfile"
else
echo "File not found: '$1'"
fi
shift
done
