Redirecting from _ to - ?

[FCRMediaLietuva]

hi everyone,

I need your help!

What's the best way to redirect a lot of urls from sign _ to sign - ?

We changed our e-shop CMS and we don't use that _ anymore.

We have more than 100.000 URLs and you can imagine that we don't to do by hand.

Any chance of doing it with .htaccess easily?

Thanks!

Yes, you can use the following two rules, in this exact order, in your .htaccess file. I'm assuming you've got mod_rewrite on.

RewriteRule ^([^]*)([^]*.) $1-$2 [N]
RewriteRule ^([^_])([^]*)$ /$1-$2 [L,R=301]

The first bracketed group in each rule -- ([^_]*) -- matches every group of characters that isn't an underscore. The first rule rewrites every underscore in the URL to a hyphen, until there's only one underscore left. At this point, control passes to the second rule, which replaces that final underscore with a hyphen, and 301 redirects to that page.
