Question

Find files with no extension in linux and mass rename them

Answer 1

+4 A:

find . -name '*JPG.jpg' -print0 | xargs -0 rename JPG.jpg .jpg
find . -name '*JPG' -print0 | xargs -0 rename JPG .jpg

rename(1) is a standard tool from util-linux

That will not rename the files that do not contain the dot before the JPG. So e.g 'media/projects/Education/St_Gregorys_School/IMG0086JPG' will not be renamed

OK, fixed that.

wRAR 2010-09-07 07:03:07

I used this fix and it works well, thanks, however - would it avoid renaming files that already have an extension/

Answer 2

A:

This is only loosely untested, but should work....

printf '#!/bin/sh\nmv -v $1 "$1".jpg' > addext.sh
chmod u+x addext.sh
find . -type f -name "*[0-9]JPG"  -exec ${PWD}/addext.sh "{}" ";"

That assumes you're running with GNU tools (which you will be, since you've tagged the question as linux).

Answer 3

A:

I would go for this beast. Not the most elegant version, but will rename any files ending with (case-insensitive) JPG.jpg

find . -type f | grep -i -E '(JPG)*\.*(JPG)+$' | while read file ; do mv $file `echo $file | perl -pe 's!(JPG)*\.*(JPG)+$!.jpg!gi'`; done

Answer 4

A:

Given the filename patterns in your example, this will do the trick:

for F in *[0-9]JPG; do mv $F $F.jpg; done

If you need a recursive solution:

find . -name "*[0-9]JPG" -exec mv \{\} \{\}.jpg \;

Simon Whitaker 2010-09-07 07:12:52

This is not recursive.

wRAR 2010-09-07 07:21:36

I know, hence "given the filename patterns in your example" - he doesn't need a recursive solution in this instance.

Adding recursive alternative...

I used this fix and it worked well except I had to modify it slightly...find . -iname "*[a-z|A-Z|0-9]JPG.jpg"

Answer 5

A:

bash 4

#!/bin/bash
shopt -s globstar
for file in **/*JPG
do
  mv "$file" "${file/JPG/.jpg}"
done

zsh knows `**/*` globbing too.
