I have found a soultion for GNU sed, and I also found something like
\1, but the Terminal tells me it's "not defined in RE".
But what I want to do is this:
If I have a string that looks like this
sinder-city1.gif, I want to make that
sinder-city.gif, now I can't just straight up replace the entire string, because I will do this to many different strings, nor can I just remove all numbers before .gif or some other pattern because if there is
I want them to stay intact.
I don't want to replace that. For matching that, I type
sed 's,[a-z]1.gif, but if I remove that, I will be left with
sinder-cit.gif. How do I match that
I want to do like this:
sed 's,[a-z]1.gif,[here is the last letter].gif,g'
It has to work on BSD sed.
