exiftool(1p) -d '%r %a, %B %e, %Y' -DateTimeOriginal -S -s -ext jpg /home/marcos/DCIM/347CANON
Read and write meta information in files
-d FMT (-dateFormat)
     Set the format for date/time tag values.  The specifics of the FMT syntax are system dependent --
     consult the "strftime" man page on your system for details.  The default format is equivalent to
     "%Y:%m:%d %H:%M:%S".  This option has no effect on date-only or time-only tags and ignores timezone
     information if present.  Only one -d option may be used per command.  The inverse operation (ie. un-
     formatting a date/time value) is currently not applied when writing a date/time tag.
-D (-decimal)
     Show tag ID number in decimal when extracting information.
  -a          (-duplicates)        Allow duplicate tags to be extracted
  -e          (--composite)        Do not calculate composite tags
  -ee         (-extractEmbedded)   Extract information from embedded files
  -ext EXT    (-extension)         Process files with specified extension
  -F[OFFSET]  (-fixBase)           Fix the base for maker notes offsets
  -fast[NUM]                       Increase speed for slow devices
  -fileOrder [-]TAG                Set file processing order
  -i DIR      (-ignore)            Ignore specified directory name
  -if EXPR                         Conditionally process files
  -m          (-ignoreMinorErrors) Ignore minor errors and warnings
  -o OUTFILE  (-out)               Set output file or directory name
  -overwrite_original              Overwrite original by renaming tmp file
  -overwrite_original_in_place     Overwrite original by copying tmp file
  -P          (-preserve)          Preserve date/time of original file
  -password PASSWD                 Password for processing protected files
  -q          (-quiet)             Quiet processing
  -r          (-recurse)           Recursively process subdirectories
  -scanForXMP                      Brute force XMP scan
  -u          (-unknown)           Extract unknown tags
  -U          (-unknown2)          Extract unknown binary tags too
  -z          (-zip)               Read/write compressed information

Special features
-t (-tab)
     Output a tab-delimited list of description/values (useful for database import).  May be combined
     with -s to print tag names instead of descriptions, or -S to print tag values only, tab-delimited on
     a single line.  The -t option may also be used to add tag table information to the -X option output.
-e (--composite)
     Extract existing tags only -- don't calculate composite tags.
-T (-table)
     Output tag values in table form.  Equivalent to -t -S -q -f.
-i DIR (-ignore)
     Ignore specified directory name.  Use multiple -i options to ignore more than one directory name.  A
     special DIR value of "SYMLINKS" (case sensitive) may be specified to ignore symbolic links when the
     -r option is used.
-m (-ignoreMinorErrors)
     Ignore minor errors and warnings.  This enables writing to files with minor errors and disables some
     validation checks which could result in minor warnings.  Generally, minor errors/warnings indicate a
     problem which usually won't result in loss of metadata if ignored.  However, there are exceptions,
     so ExifTool leaves it up to you to make the final decision.
-r (-recurse)
     Recursively process files in subdirectories.  Only meaningful if FILE is a directory name.  By
     default, exiftool will also follow symbolic links to directories if supported by the system, but
     this may be disabled with "-i SYMLINKS" (see the -i option for details).
-S (-veryShort)
     Very short format.  The same as -s2 (or two -s options).  Tag names are printed instead of
     descriptions, and no extra spaces are added to column-align values.
-s[NUM] (-short)
     Short output format.  Prints tag names instead of descriptions.  Add NUM or up to 3 -s options for
     even shorter formats:
-ext EXT, --ext EXT (-extension)
     Process only files with (-ext) or without (--ext) a specified extension.  There may be multiple -ext
     and --ext options.  Extensions may begin with a leading '.', and case is not significant.  For

         exiftool -ext .JPG DIR            # process only JPG files
         exiftool --ext crw --ext dng DIR  # process all but CRW and DNG
         exiftool --ext . DIR              # ignore if no extension

     Using this option has two main advantages over specifying "*.EXT" on the command line:  1) It
     applies to files in subdirectories when combined with the -r option.  2) The -ext option is case-
     insensitive, which is useful when processing files on case-sensitive filesystems.
