Re: Slightly OT - Matching a strange character

on unix you may use od -c <filename> to get a dump of all of the characters escaped. output is something like this:

% head -2 /etc/hosts 
##
# Host Database
% head -2 /etc/hosts | od -c 
0000000    #   #  \n   #       H   o   s   t       D   a   t   a   b  
+ a
0000020    s   e  \n                                                  
+  
0000023

Right -- though a hex dump tends to be more useful in cases like this. And of course, if the odd byte happens to be near the end of a large file, this approach can be tedious... Here's my favorite -- it prints a histogram of byte values in a data stream or file: `#!/usr/bin/perl use strict; my @ch; while (<>) { $ch[ord()]++ for ( split( // )); } printf "%6d %.2x\n", $ch[$_], $_ for ( grep {$ch[$_]} 0..$#ch );` [download] And it would be easy to make a couple additions/alterations so that it tabulates utf8 characters instead of bytes.

Or just `cat -v`?	[reply] [d/l]
