Shell Programming and Scripting

I would like to search for regex in the exif data of a large collection of files (mostly jpg, some nef). For instance "grep_exif Tokyo *.jpg" should return the file names of all files which have "Tokyo" in their exif data.

Exiftool could be used to extract the data. I don't really need to grep all of the exif data, but only things like city, location, country, keywords, etc, So if there is a quicker or more convenient tool than exiftool that could be used instead.

Two nice-to-have-not necessary requirements:
1. be insensitive to capitalization (Tokyo/tokyo/tOkYo/...)
2. add options to search only in the City field or only the Keyword field

Code:

 
for i in *.jpg
do
        echo "------------------$i----------------"
        exiftool "$i" | awk '/city/ || /location/ ||/country/ ||/keywords/'
done

Thanks for the reply, but it is not exactly what I am looking for. This script


I want a grep like functionality, so the script should show me the file names in which a certain string (to be supplied on the command line) exists in the exif data.

Surely you can modify it into what you're looking for, though, now that you've seen the principles?

Also -- what's your system?

Not sure what you mean by principles. The script posted just lists the content of city/location/country/keywords and doesn't have any functionality like grep at all.

System is linux/debian. I don't really care what scripting language.

Gash Shell script built on @itkamaraj post. Count the number of times the case-insignificant string occurs in each file. Untested.

Code:

search="$1"
for i in *.jpg
do
        echo "------------------$i----------------"
        count=$(exiftool "$i" | awk '/city/ || /location/ ||/country/ ||/keywords/' | grep -ic "${search}")
        if [ $count -gt 0 ]
        then
               echo "String found in file: $i"
        fi
done

Thank you.
