in thread in-place edit, regex, one-liner

Woo-hoo!   -pe instead of -ne did the trick!   Thanks a bunch, mdillon.

perl -i.bak -pe 's/img src=\"image\.gif\"/img src=\"\/Images\/image\.gif\"/g' file.html

Here's that syntax sans toothpicks:
perl -i.bak -pe 's///g' *.html

    I think you can cut that down a bit.

    perl -pe -i.bak 's!(img  src=")(image\.gif")!$1/Images/$2!g' *.html

    (I haven't tested it, but I think it's okay.)

      I like it, thanks chromatic.   May I throw a slight curve in the fairway?
      A quick dig in The Owl leads me to think something like this will match reference any image of alphanumeric name.   How close am I?

      perl -i.bak -pe 's!(img  src=")(\w+?\.(gif|jpg|jpeg|png)")!$1/Images/$2!g' *.html

      Update: The above one-liner was tweaked, and now works.

          Changes this:

      <img src="12345.gif"> <img src="1b3e5.jpg"> <img src="1B3Df.jpeg"> <img src="abcde.png">

          To this:
      <img src="/Images/12345.gif"> <img src="/Images/1b3e5.jpg"> <img src="/Images/1B3D5.jpeg"> <img src="/Images/abcde.png">
      And saves original files as ".bak".
