Bash: Rename all files in current directory to lowercase

Just some code i used to rename my holiday pictures to lowercase.

find ./* -type f -maxdepth 0 | while read upName; do loName=`echo "${upName}" | tr '[:upper:]' '[:lower:]'`; mv "$upName" "$loName"; done

find lists all files in current directory. -type f lists only files, not directorys.

The while loop iterates over the file list.

echo | tr makes the filename variable lowercase.

mv finally moves the file.

Thanks to Veikko for the maxdepth hint.

    If you have subdirectories than they will get listed by the find command as well.
    That is not what the heading describes.

    find ./* -type f -maxdepth 0

    will only show the files of the current directory and no subdirectories
