Rename files using a regex with bash [duplicate]

Answer 1

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

Answer 2

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

Answer 3

If you are on a linux, check special rename command which would do just that - renaming using regular expressions.

rename 's/^images\/(.+)/test\/$1.png/s' images/*.png

Otherwise, write a bash cycle over the filenames as catwalk suggested.

Answer 4

Try this:

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