Search and replace via command line

I'm trying to replace the HTTP protocol for HTTPS in all the internal links on one of my sites. I'm attempting it with the following but it just throws out errors, I guess the forward slashes. To be clear, I want to change http://www.example.com/ to [example.com...]

This is what I've got so far, this really isn't my areas at all but if I can make it work it'll save me a LOT of time. . .

perl -pi -e 's/"http://www.example.com/"https://www.example.com/g' *.html

you might want to use a different delimiter (e.g. a vertical bar instead of a forward slash)

Thanks, I'm now using this. . .

perl -pi -e 's|"http://www.example|"https://www.example|g' *.html

It works for the most part and doesn't seem to break anything. The only thing however is it seems to struggle when I use it on .php files when the target string to replace is in an if/else statement i.e. the target is not replaced.

Sure. The following is the .php include that is pulled into the page template of part of the site. . .

In the above, the http:www.examp is not being replaced with [examp...]
My suggestion it might be something to do with the if/else is just a wild guess.

perl -pi -e 's|"http://www.example|"https://www.example|g' *.html

that's a double quote in front of the http:

that's single quotes in front of the https:

so you have every combination except for the pattern specified...

By the way is there a way to make this recursive, avoiding the need to visit every directory?

There is, but be careful with it. I would use the -pi.bak syntax to create backup files just in case.

This would run the command, recursively, on every normal file (not on directories), starting with files in the current directory:

find . -type f -exec perl -pi.bak -e 's/was/is/g' {} \;

"normal file" would include "hidden" files, like .htaccess.
