Hi
I'm trying to create a list of pictures that contain GPS information.
I have all the picture that I need to examin in one directory and I have a bit of script that works, but not as good as I would like.
| Code: | #!/bin/bash
# My first script
for file in 'ls -1';
do if exiftool *.jpg | grep 'GPS L';
then
exiftool *.jpg | grep 'File Name\|GPS L' > test.txt
else
echo "Negativ"
fi
done |
This code scans all the *.jpg files in a dir for GPS information stored in EXIF. Then it saves the filename and the GPS information to a file called test.
My problem how ever is that it saves all the filenames, also the ones not containing EXIF GPS information.
| Code: |
File Name : noEXIFtest.jpg
File Name : noEXIFtest2.jpg
File Name : EXIFtest2.jpg
GPS Latitude Ref : North
GPS Longitude Ref : East
GPS Latitude : 34 deg 56' 17.78" N
GPS Longitude : 135 deg 38' 41.91" E
File Name : EXIFtest.jpg
GPS Latitude Ref : North
GPS Longitude Ref : East
GPS Latitude : 34 deg 56' 17.78" N
GPS Longitude : 135 deg 38' 41.91" E
File Name : noEXIFtest.jpg |
What Am I doing wrong?
J;-)

Can you post the full output from exiftool on one of the file that does not contain GPS info but does appear in the list.

These line are exiftool'ing ALL jpgs so it will always find at least one match:
| Code: |
do if exiftool *.jpg | grep 'GPS L';
then
exiftool *.jpg | grep 'File Name\|GPS L' > test.txt |
you probably want to do
| Code: |
do if exiftool $file | grep 'GPS L';
then
exiftool $file | grep 'File Name\|GPS L' > test.txt
|
you could probably achieve the same result with
| Code: |
exiftool *.jpg | egrep "File Name|GPS L" | egrep -B1 "GPS L" > test.txt |

This last bit works like a charm.
