This option is mainly used for extracting embedded images or other binary data, but it may also be useful for some text strings since control characters (such as newlines) are not replaced by '.' as they are in the default output. Output requested metadata in binary format without tag names or descriptions ( -b or -binary). Also note that the second command above will produce warning messages for any tags which are not writable.Īs well, the -sep option should be used as in the second command above to maintain separate list items when writing metadata back to image files, and the -struct option may be used when extracting to preserve structured XMP information. For instance, the FileName and Directory tags are excluded in the example above to avoid renaming and moving the destination file. Note: Be careful when copying information with this technique since it is easy to write tags which are normally considered 'Unsafe'.

If no destination group is specified, the information is written to the preferred group. 0All writes to the same family 0 group as the source). A destination group and/or tag name of All or * writes to the same family 1 group and/or tag name as the source (but the family may be specified by adding a leading number to the group name, eg.

Wildcards are allowed in both the source and destination tag names. Source and/or destination tags may be prefixed by a group name and/or suffixed by #. Note that this argument must be quoted to prevent shell redirection, and there is no = sign as when assigning new values. Has no effect unless SRCTAG exists in SRCFILE.

WritingĮxiftool - TAG[+- DSTTAG'' on the command line after -tagsFromFile, and causes the value of SRCTAG to be copied from SRCFILE and written to DSTTAG in FILE.
