Problem Extracting Metadata on PDF Files on RHEL

[dmphan2]

Hi,

With a same command and parameters, I can extract metadata on Windows, but not on Red Hat Enterprise Linux.  Would anyone able to help me figuring why? Output from the two platforms as well as the PDF file are attached

Windows: exiftool --ZIP:* --Track1:* --PDF:* --XMP-xmpMM:Subject --XMP-photoshop:History --XMP-crss:SavedSettings* --IFD0:ProfileHueSatMapData1 --IFD0:ProfileHueSatMapData2 --XMP-crs:all --ExifIFD:ImageWidth --ExifIFD:ImageHeight -m -X -c "%.6f Degrees" x:\temp\AHB2014r54037.pdf > x:\temp\AHB2014r54037.pdf.windows.txt

RHEL: exiftool --ZIP:* --Track1:* --PDF:* --XMP-xmpMM:Subject --XMP-photoshop:History --XMP-crss:SavedSettings* --IFD0:ProfileHueSatMapData1 --IFD0:ProfileHueSatMapData2 --XMP-crs:all --ExifIFD:ImageWidth --ExifIFD:ImageHeight -m -X -c "%.6f Degrees" /dev/temp/AHB2014r54037.pdf > /dev/temp/nmah_pdf/AHB2014r54037.pdf.linux.txt

My pdf file is over 14 MB, I could not upload it.

You should quote the arguments containing wildcards if you don't want the shell to expand them on Linux.

Also, if the PDF is encrypted, you may need to install Digest::SHA.  Use "exiftool -ver -v" to see the available optional libraries.

Hi Phil,

Thank you for looking at this issue.  Here is the output of that command.  Do you know which library I have to install?

[tuser@si-dams401 mm16]$ exiftool -ver -v
ExifTool version 10.48
Perl version 5.016003 (-C0)
Platform: linux
Optional libraries:
  Archive::Zip                 (not installed)
  Compress::Zlib               (not installed)
  Digest::MD5                  (not installed)
  Digest::SHA                  (not installed)

Check the ExifTool output for warnings.  It should tell you which one(s) it wants.

Thank you Phil!  After my system admin added those missing Perl libraries, exiftool was able to extract PDF metadata.
