Unix Bash rename files using a regex.

Question

Hi everyone!

I would like to rename all files from a folder using a regex(add a name to the end of name) and move to another folder.

It my opinion, it should be looking like this:

mv -v ./images/*.png ./test/*test.png, but it is not working.

Can anyone suggest me a solution?

Thanks in advance!

Answer 1

Try this:

for x in *.png;do mv $x test/${x%.png}test.png;done

Answer 2

If you are on a linux, check special rename command which would do just that - wildcard renaming. Otherwise, write a bash cycle over the filenames as catwalk suggested.

Answer 3

$ for old in ./images*.png; do
    new=$(echo $old | sed -e 's/\.png$/test.png/')
    mv -v "$old" "$new"
  done

Answer 4

Yet another solution would be a tool called "mmv": mmv "./images/*.png" "./test/#1test.png"
