Pro's please help with regular expression

hi,

tried to find a solution with searching in forums and google.... maybe it's a bit to complex....

obviously for me

###

I have to replace many files, for example:

COP_LAND_HDTV_ARD.ts to: COP_LAND_[HDTV]_[ARD].ts
BRAEUTE_SDTV_3SAT.ts to: BRAEUTE_[SDTV]_[3SAT].ts
FRANZ_UND_ANNA_HDTV_ORF2.ts to: FRANZ_UND_ANNA_[HDTV]_[ORF2].ts

I mean basically the next to last
"_" should be replaced with: "_["

the last "_" should be replaced with: "]_["

and ".ts" should be replaced with "].ts"

...... any ideas with what kind of pattern i could do this ??
(I use better file rename)

thx in advance for help !

I'd say something about those filenames but I know it wouldn't change anything.

Use

to match...

requinix,

first of all: thank you very much for your help !

as i'm really a beginner.... at first I didn't understand anything !!

but after some trial and error, I figured out what I had to do - you are awesome !!! - thx thx thx

and for other "beginners":

in better file rename

change: entire file name
action: replace using regular expressions

pattern: ^(.*)_([^_]+)_([^_]+)\.ts
substitution: \1_[\2]_[\3].ts

###

and just cause i'm curious....
what you'd say about the filenames ??

It's nothing, don't worry about it.

I gave you half of the answer because I thought you could come up with the other half by yourself. And you did
