More SEG-Y Command Line Stuff: Binary header

A really sleazy bash script to read SEG-Y binary header data.  Basically a file stuffed full of command line stuff.

#!/bin/bash
echo -n "SEG-Y file name:  "
read _segyin


_jobid=$(hexdump -C -s 3200x -n 4 $_segyin | awk '{print $2 $3 $4 $5}')
_linenumber=$(hexdump -C -s 3204x -n 4 $_segyin | awk '{print $2 $3 $4 $5}')
_reelnumber=$(hexdump -C -s 3208x -n 4 $_segyin | awk '{print $2 $3 $4 $5}')
_tracesperrec=$(hexdump -C -s 3212x -n 2 $_segyin | awk '{print $2 $3}')
_auxtraces=$(hexdump -C -s 3214x -n 2 $_segyin | awk '{print $2 $3}')
_sampleinterval=$(hexdump -C -s 3216x -n 2 $_segyin | awk '{print $2 $3;}')
_samplespertrace=$(hexdump -C -s 3220x -n 2 $_segyin | awk '{print $2 $3;}')
_filesize=$(stat -c%s $_segyin)
_formatcode=$(hexdump -C -s 3224x -n 2 $_segyin | awk '{print $2 $3;}')
