Rename all files in directory from $filename_h to $filename_half?

Question

Dead simple.

How do I rename

05_h.png
06_h.png

to

05_half.png
06_half.png

At least, I think it\

Answer 1

Just use bash, no need to call external commands.

for file in *_h.png
do
  mv "$file" "${file/_h.png/_half.png}"
done

Do not add #!/bin/sh

For those that need that one-liner:

for file in *.png; do mv "$file" "${file/_h.png/_half.png}"; done
