Hello,
I've read something like this:
exiftool '-IPTC:DateCreated<${EXIF:DateTimeOriginal}+01:00' file
and this does work, but where does the variable ${EXIF:DateTimeOriginal} come from, it is not a bash variable but one can use it??
thanx

See the section on the -tagsFromFile option in the application documentation (https://exiftool.org/exiftool_pod.html#item__2dtagsfromfile_srcfile_or_fmt):
An extension of the redirection feature allows strings involving
tag names to be used on the right hand side of the "<" symbol with
the syntax "'-DSTTAG<STR'", where tag names in STR are prefixed
with a "$" symbol. See the -p option for more details about this
syntax. Strings starting with a "=" sign must insert a single
space after the "<" to avoid confusion with the "<=" operator
which sets the tag value from the contents of a file. A single
space at the start of the string is removed if it exists, but all
other whitespace is preserved.
