Exiftool command in Bash for-loop not working

Question

I'm trying to write and overwrite jpg metadata with exiftool in a bash for-loop, but a specific command won't work in the loop. I want to overwrite the gpstimestamp with the datetimeoriginal data, this works if executed on the commandline, but not in the script..

for f in $(ls *.jpg); do

    [... stuff that works]

    exiftool "-gpstimestamp<datetimeoriginal" $f
done

Any ideas why this isn't working in the loop?

Answer 1

The for loop can be done in a simpler way:

#!/bin/bash
for f in *.jpg
do

    [... stuff that works]

    exiftool "-gpstimestamp<datetimeoriginal" $f
done

Note: You instead of running a for loop, you can execute exiftool to process all *.jpg files in the directory using:

exiftool info

exiftool "-gpstimestamp<datetimeoriginal" -ext jpg .

exiftool man

-ext EXT (-extension) Process files with specified extension
