2322%.%
3434*
-----
but why 4343$$44 is showing as numeric value ???
also 343$34
show as numeric and showing 3434

This expression is working for all other but not when the value contain $
can any one help ??

also i tried with echo $var | sed -n '/^[0-9][0-9]*$/p' same thing happened
any thing consist of 0-9 should be considered as numeric , this sed expression working fine except for the value 445$$343 or 23$899 some thing like this which contain $ , it is considering that as numeric .

sigfind

SIGFIND(1)						      General Commands Manual							SIGFIND(1)

NAME

       sigfind - Find a binary signature in a file

SYNOPSIS

       sigfind [-b bsize ] [-o offset ] [-t template ] [-lV] [ hex_signature ] file

DESCRIPTION

       sigfind	searches  through  a  file  and  looks for the hex_signature at a given offset.  This can be used to search for lost boot sectors,
       superblocks, and partition tables.

ARGUMENTS

       -b bsize
	      Specify the block size in which to search.  The default is 512 and the value must be a multiple of 512.

       -o offset
	      Specify the offset in a block in which the signature must exist.	The default is 0.

       -t template
	      Specify a template name that defines the signature value and offset.  Run with no options to get a list of supported templates.

       -l     The signature is stored in little-endian ordering and must therefore be reversed.

       -V     Display version

       [hex_signature]
	      The binary signature that you are searching for.	It must be given in hexadecimal format.  This argument must exist  if  -t  is  not
	      used.

       file   Any raw data.

EXAMPLES

       sigfind -o 510 -l AA55 disk.dd

       sigfind -t fat disk.dd
