Linux将now.jpg.1重命名为spy_1.html

Question

I want to use linux to rename 10 files.

now.jpg to spy_.html

And the other 9 should be

now.jpg.1 to spy_html.1

now.jpg.2 to spy_html.2

And so forth.

So far I have come up with this:

for f in *.jpg
do
mv “$f” “(“%s”%p”%i”%o”%n”%_).html”
done

But it doesn't work. Any tips appreciated.

Answer 1

You could use regular expression to capture the optional numeric extension and add it to the target file name. This should work with bash:

for f in *.jpg*
do
  if [[ $f =~ now\.jpg(\.[0-9])? ]]; then
    mv "$f" "spy.html${BASH_REMATCH[1]}"
  fi
done

assuming you want spy.html[.#] . If you want an underscore for the files with the numerical extension, ie spy_html.1 , it would be easier to issue two commands, one for now.jpg and one loop for the now.jpg.* .
