You want to use either chr, or sprintf's %c.

perl -e 'print map { chr } 0x61, 0x62, 0x63'
perl -e 'printf "%c%c%c", 0x61, 0x62, 0x63'

thanks DamnDirtyApe, adrianh, sauoq and merlyn for the great advice. To give you an idea as for the basis of my question, I'm interesting in building a small tool that will convert hex content in a Snort IDS signature to a char value and, conversely, take a known attack string and quickly convert it to hex for signature creation. I'll probably use something like

print unpack "H*", "abc";

for the char to hex conversion.

cheers! -semio

You actually prefer

printf "%x%x%x",ord('a'),ord('b'),ord('c')

to

print unpack "H*", "abc"

!!??! Remind me not to hire you.

Use chr with hex... for example

use strict;
use warnings;
use Test::More tests => 1;

is(chr(hex('62')), 'b', 'hex -> char worked');

1..1
ok 1 - hex -> char worked

perl -le 'print pack "ccc", 0x61, hex(62), hex("63")'
