[Solved] Script Rename Regex and Extension

[GreetingsFromPoland]

hi! i am currently using this in my hamburger menu :

Code: Select all

rename r, "-[^-]*$ > .mkv";

and it works great. up to this point all the files i use this on have been MKVs. now i have other extensions as well.

what needs to change in the regex to tell it to leave the existing extension as-is ? right now, i use the command (which works, but renames everything to .mkv), then use the Set Extension option under Rename to set it back.

Provide real world renaming examples...

or otherwise, wild guessing:
rename r, "(.*?)(-[^-]*?)(\.[^.]+)$ > $1$3";

hi!
edit you're too fast ! your updated post worked great ! thank you.

as-is, it will rename "01-Introduction-1.mkv" to "01-Introduction.mkv" and it's great (handbrake appends -1, -2, etc. to conversions).

now i am converting to mp4, so "02-Understanding the Effect Hook-2.mp4" becomes "02-Understanding the Effect Hook-2.mkv" due to the mkv setting in the regex rename.
i'd like to have the rename regex just leave the extension alone, regardless of what it is, so :

01-Introduction-1.mkv would be 01-Introduction.mkv
02-Understanding the Effect Hook-2.mp4 would be 02-Understanding the Effect Hook.mp4
03-Effect Dependencies-3.mp3 would be 03-Effect Dependencies-3.mp3

(instead of all them renaming to mkv).

That's what the regex in my first post does...
