Editing/Viewing IPTC data with exiftool

[jmexer312]

I am trying to edit and view whole "IPTC" data of an image, is there any one-liner command to only list them all? Thanks.

found this command `exiftool all -G1 -a -s 1.JPG`, is it only for view or also updates anything?

Which "IPTC" data? There's the old standard of IPTC IIM, and the newer tags of IPTC core/Ext. But the latter is only part of the IPTC Photo Metadata Standard, not all of it.

To see all of it, you could use
exiftool -G1 -a -s -IPTC:All -XMP:All /path/to/files/
but there probably would be XMP data in the output that isn't part of the IPTC Photo Metadata Standard.
