Rename file if Software tag is populated

[slickdawg]

I'm trying to identify all .jpg files that have been "contaminated" by the Microsoft Photo viewer.  I don't want to add all of that tag to the filename, just add microsoft to the file name if the tag is populated.


Software                        : Microsoft Windows Photo Viewer 6.1.7600.16385

so IMG_0001.JPG would become IMG_0001_Microsoft.JPG

I was going to do this with grep and a bash script, but I think exiftool would be better.  Any suggestions?

Try
exiftool -if "$Software=~/Microsoft Windows Photo Viewer/" -Filename=%f_Microsoft.%e /path/to/files/

Change the double quotes to single quotes if you're using Mac/Linux/Powershell.

Thank you StarGeek!  That worked perfectly, unlike my trials.
