pecomato - a portable picture-embedded metadata processor

pecomato [OPTION...] OP [EXPR] FILE [FILE...]

pecomato [OPTION...] OP [EXPR] @FILE

usage of form OP EXPR only concerns OP mode dump-value, see below.

use @file to read a list of files from that file. the file must contain exactly one filename to process per line (don't escape anything, filenames are taken as-is).

pecomato is basically designed to display any kind of information embedded in picture files, as well as checking, filtering, extracting, removing, adding and fixing such information. In other words, it's a metadata processor.

It supports the following file formats: JPEG/JFIF, Adobe PSD and FFO, raw IPTC. And it knows about the following metadata formats: JFIF, IPTC, Exif, Adobe and Fotostation. More file and metadata formats might be supported later: TIFF, etc.

One of its main goals is to check the validity of parsed metadata as well as optionally check the strict compliance to official standards. On another hand, it aims to provide ways of fixing broken or not compliant chunks as well as providing general basic functions to manipulate the metadata.

general options:

show version number then exit
show this usage help then exit
list all supported embedded data structures
define verbosity (see possible values below)
perform full checks to test the strict validity and compliance of structures to official formats

filtering and extracting options:

create backup files of (re)written files if necessary
target directory for all written files
fix metadata inconsistencies when possible

extracting options:

extract and save metadata to a standalone file (see below for a list of metadata types that can be extracted)
define what filename extension to use when writing metadata that is extracted (default: .iptc)
append extension to original filename when saving the extracted metadata (default: replace original file extension)

filtering options:

a filter expression describing the datasets to keep
or a file containing a list of datasets to keep, all other datasets will be filtered out. if not used, all datasets will be kept
a filter expression describing the datasets to filter out
a file containing a list of datasets to filter out, all other datasets will be kept. if not used all datasets will be kept
a filter edit expression describing the datasets to add
or a file containing a list of datasets to add. datasets won't be inserted if that breaks compliance to the standards
don't override original file, create *.rewrite file. this option only affects rewriting of source files

dump options:

max column for wrapping (num must be in range [8-1024]). default is to dump unwrapped

just check embedded data structures
show embedded data (headers only)
show all embedded data (including values)
show requested value (headers only)
filter embedded data (see -i, -e and --edit)

same as filter include/exclude expression, see below:

where <record> can be either:

examples:
