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 :-)
