Chop off extra junk in file names

<< < (3/3)

AbteriX:
Please note that Nicholas don't want to remove the last underscore, e.g. there are only 4 signs to remove.

nkormanik:
Thanks AbteriX for pointing that out.  Yes, I want the last underscore to remain.

As for what's between the last underscore and the period, it's variable -- from one to six digits.  That's really the crux of the problem.  The 'junk' varies in length.  Need to cut out that junk.

Probably a magic RegEx code is called for.  Look forward to the RegEx gurus coming back with updated code (sorry I made the mistake about which underscore...).

jgpaiva:
Hi, for ReNamer to keep the last underscore, you can use: (_.*_).*

AbteriX:
Nicholas, since the RegEx differs from tool to tool,... do you have an favorite now?

An RegEx for scarabee's Siren Renamer would be:
%b(s/(.+_).+/$1/).%e

Note that you can use also f.ex. den4b's ReNamer with an Rearrange Rule like this:

FROM:
_50501_22004_22404_3000.png
or
_50501_22004_22404_300012345678.png

TO:
_50501_22004_22404_.png

USE:
ReNamer Rearrange Rule:
Split by delimiters "_"
New pattern "$1_$2_$3_$4_"
(skip extension)

See > http://www.den4b.com/wiki/ReNamer:Rules:Rearrange

Also note that ReNamer has an Analyze Dialog to test such issues without the need to have the file names in real on your disk:

nkormanik:

den4b's ReNamer looks really good.  I still would like to try the others, though.
