NAME

       jpeginfo - prints information and tests integrity of JPEG/JFIF files.

SYNOPSIS

       jpeginfo [ options ] [ filenames ]

DESCRIPTION

       jpeginfo is used to generate informative listings of jpeg files, and also to check jpeg files for errors.
       Program also supports automatic deletion of broken jpegs.

OPTIONS

       Options may be either the traditional POSIX one letter options, or the GNU  style  long  options.   POSIX
       style options start with a single ``-'', while GNU long options start with ``--''.

       Options offered by jpeginfo are the following:

       -c, --check
             Check files also for errors. (default is just to read the headers).

       -C, --comments
             Display file comments (from COM markers).

       -d, --delete
             Delete files that have errors. (default is not to delete any files).

       -f<filename>, --file<filename>
             Read  filenames  to  process  from given file. To use standard input (stdin) use '-' as a filename.
             This is alternative to default where filenames are given as parameters to the program.

       -h, --help
             Display short usage information and exits.

       -5, --md5
             Calculates MD5 checksum for each file.

       -i, --info
             Displays even more information  about  each  picture.  Prints  image  coding  (Huffman/Arithmetic),
             density (in dpi/dpc), and whether CCIR601 sampling was used or not.

       -l, --lsstyle
             Uses alternate listing format (ls -l style).

       -v, --verbose
             Enables verbose mode (positively chatty).

       --version
             Displays program version.

       -q, --quiet
             Quiet mode, output just the jpeg infos.

       -m<mode>, --mode=<mode>
             Sets the delete mode, meaningful only when used with -d flag.  Mode can be one of the following:

             all    files  containing  any  type  of  errors/warnings,  not necessarily preventing the decoding.
                    (default)

             erronly
                    only files with serious errors (ie. cannot be decoded at all).

BUGS

       None, so far :-)
