Hi, Brand new to exiftool command line, but not afraid! Been scripting in batch for a couple of years, so not completely foreign to the idea. What i want in the end is to remove any image description tags that say "OLYMPUS DIGITAL CAMERA". I've been following this excellent tutorial (http://carlibrary.org/ExifTool.htm) and modifying it form my own purposes. While exporting tags to csv, fiddling with the data, then reimporting the tags will work (and is an excellent way to review all tags easily), i am looking to make it a little more automated. i've been trying to adjust what i've learned from (http://ninedegreesbelow.com/photography/exiftool-commands.html) but that tute basically deals with copy/move methods, but i do like how the blogger explains each bit. i'm having trouble finding examples of how to use an IF THEN (ELSE) clause in exiftool speak. What i want to script is something that does two things. First, to remove the value in the tag if the value meets criteria: IF [ImageDescription]="OLYPMUS DIGITAL CAMERA" THEN [ImageDescription]="" perhaps something like (e for equals?): exiftool -r -if '$ImageDescription e "OLYMPUS DIGITAL CAMERA"' -ImageDescription="" -overwrite_original can i have multiple ifs in one line (to cover all the description tags, whether EXIF, IPTC, etc), or is it just one command per line? no problems either way, it's all going into a windows batch file anyhow. The second thing i want to do, is restrict the operation to work only if the creation date is greater than whatever date i choose to put in there. this is that that the script doesn't have to bother with all the files, just whatever new ones i have since my selected date. though i guess this is a bit of a moot idea because the script will iterate through all the files anyway to determine the date, so i guess i just wanted to know if this was worth scripting in at all. that said, i do have a txt log file of my file transfers (i keep a .bat on every SD, and use xcopy to only copy new files. those that are copied are logged into the txt, the list of files in the log are then part of the 'exclude' clause of the xcopy for next time) - perhaps i can utilise this log somehow to iterate exiftool command through only those files.
