The simplest way I know. Show Sample Output
22rename 'y/A-Z/a-z/' * -
or, to process a single directory:
for f in *; do mv $f `echo $f |tr '[:upper:]' '[:lower:]'`; doneShow Sample Output9find . -type f|while read f; do mv $f `echo $f |tr '[:upper:]' '[ :lower:]'`; done -
This will convert filenames from uppercase to lowercase. I find this useful after downloading images from my digital camera. This works for English, but other languages may need something slightly more complex like this:
for i in *; do mv "$i" "$(echo $i|tr [:upper:] [:lower:])"; doneAlso, the quote marks aren't necessary if your filenames don't contain spaces.5for i in *; do mv "$i" "$(echo $i|tr A-Z a-z)"; done -
2find my_root_dir -depth -exec rename 's/(.*)\/([^\/]*)/$1\/\L$2/' {} \;
-
easier way to recursively change files to lowercase using rename instead
1find . -depth -print -execdir rename -f 'y/A-Z/a-z/' '{}' \;
