Need to extract value from a variable
Hello All,

Code:
output=[record
  bdfo_len      73
  bdfo_key      "     200000016"
  bdfo_param_no "000"
  parm01        NULL
  parm02        NULL
  parm03        NULL
  parm04        NULL
  parm05        NULL
  parm06        NULL
  parm07        NULL
  parm08        NULL
  parm09        NULL
  parm13        NULL
  parm16        NULL
  parm017       NULL
  parm18        NULL
  parm93        NULL
  parm94        NULL
  parm96        NULL
  parm97        NULL
  parm83        NULL
  header        [record
                  bdfo_run_date     41991
                  bdfo_file_id      "GYFL3027"
                  bdfo_centre_id    "G"
                  bdfo_sbi_file_ind "YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY"]
  trailer       NULL
  data          NULL]

I need to extract bdfo_run_date value which is '41991' out of this, any pointers will be greatly appreciated.

ppmtosixel

ppmtosixel(1)                                                 General Commands Manual                                                ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.  The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
              pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order  of  magni-
              tude larger than a compressed file and prints much slower.

       -margin
              If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
              fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater  than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
