Cuddeback Cameras use UserComment for Data

[ronoc]

I run a few cuddeback trap cams all the files get emailed me to named as T00001.jpg, T00002.jpg and the counter gets reset every email. I have a small bash script that can rename them by date/time from the createdate field, but I'd like to prefix them with an item from the UserComment field.

Depending on the model of the camera (I have two currently) the usercomment is one of these two:

MR=C.1,AD=3/10/2022,LD=38,BT=11,RD=36,LH=0,LI=22,BL=7959,BP=50%,BS=Ext,BD=37,BI=30,CF=Disabled,IR=Indoors,WL=850nm,EX=Centered,ID=TRIPOD,LO=001,MA=1B034C1A926E,SM=SUR,DD=FAP,DI=1,DV=OFF,DL=OFF,ND=FAP,NI=1,NV=OFF,NL=OFF

MR=C.1,AD=11/6/2020,LD=32,BT=12,RD=0,LH=0,LI=29,BL=5290,BP=50%,BS=Int,BD=0,BI=2,CF=Enabled,EX=Centered,ID=SFP,LO=005,MA=2818C978936E,SM=SUR,DD=FAP,DI=1,DV=OFF,DL=OFF,ND=FAP,NI=1,NV=OFF,NL=OFF

I'd like to prefix the filename with the ID= from it's Usercomment. I was using

ID=$(exiftool -A $img | awk -F"[,=]" '/ID=/{print $34}')
exiftool -d $ID-%Y-%m-%d_%H%M%S%%-c.%%e "-filename<CreateDate" $img; but that doesn't work with the other model because 34th value is not the ID in the 2nd entry I listed above.

Any thoughts?

You can use regex to extract the ID.
exiftool -d %Y-%m-%d_%H%M%S%%-c.%%e '-FileName<${UserComment;m/ID=([^,]+),/;$_=$1;}-$CreateDate' file.jpg

Example output

YES! Regex! I could NOT for the life of me remember the tool I needed to google for.

Usually writing it all out to post triggers something, but this time nothing. Thank you StarGeek!

This work perfect after I switched the double quotes to single for linux

Yep, that's why the command line I first listed had them   I'm on Windows so my example had to use double.
