Here's another way using awk:

Code:

# od -bc < data.file

isgraph

ISGRAPH(3)						   BSD Library Functions Manual 						ISGRAPH(3)

NAME

     isgraph -- printing character test (space character exclusive)

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <ctype.h>

     int
     isgraph(int c);

DESCRIPTION

     The isgraph() function tests for any printing character except space (' ') and other locale-specific space-like characters.  The value of the
     argument must be representable as an unsigned char or the value of EOF.

     In the ASCII character set, this includes the following characters (preceded by their numeric values, in octal):

     041 ``!''	   042 ``"''	 043 ``#''     044 ``$''     045 ``%''
     046 ``&''	   047 ``'''	 050 ``(''     051 ``)''     052 ``*''
     053 ``+''	   054 ``,''	 055 ``-''     056 ``.''     057 ``/''
     060 ``0''	   061 ``1''	 062 ``2''     063 ``3''     064 ``4''
     065 ``5''	   066 ``6''	 067 ``7''     070 ``8''     071 ``9''
     072 ``:''	   073 ``;''	 074 ``<''     075 ``=''     076 ``>''
     077 ``?''	   100 ``@''	 101 ``A''     102 ``B''     103 ``C''
     104 ``D''	   105 ``E''	 106 ``F''     107 ``G''     110 ``H''
     111 ``I''	   112 ``J''	 113 ``K''     114 ``L''     115 ``M''
     116 ``N''	   117 ``O''	 120 ``P''     121 ``Q''     122 ``R''
     123 ``S''	   124 ``T''	 125 ``U''     126 ``V''     127 ``W''
     130 ``X''	   131 ``Y''	 132 ``Z''     133 ``[''     134 ``''
     135 ``]''	   136 ``^''	 137 ``_''     140 ```''     141 ``a''
     142 ``b''	   143 ``c''	 144 ``d''     145 ``e''     146 ``f''
     147 ``g''	   150 ``h''	 151 ``i''     152 ``j''     153 ``k''
     154 ``l''	   155 ``m''	 156 ``n''     157 ``o''     160 ``p''
     161 ``q''	   162 ``r''	 163 ``s''     164 ``t''     165 ``u''
     166 ``v''	   167 ``w''	 170 ``x''     171 ``y''     172 ``z''
     173 ``{''	   174 ``|''	 175 ``}''     176 ``~''

RETURN VALUES

     The isgraph() function returns zero if the character tests false and returns non-zero if the character tests true.

COMPATIBILITY

     The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
     obsolete and may not be supported in future releases.  The iswgraph() function should be used instead.

SEE ALSO

     ctype(3), isalnum_l(3), iswgraph(3), ascii(7)

STANDARDS

     The isgraph() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
