Easy. See "man perlfunc", especially "pack", "unpack" and "vec" (there
are actually some examples there). Basically:
# makes the binary representation of an integer:
| [EMAIL PROTECTED]:~$ perl -e 'print unpack("b*", 100), "\n"'
| 100011000000110000001100
# makes an integer out of a binary representation:
| [EMAIL PROTECTED]:~$ perl -e 'print pack("b*", "100011000000110000001100"),
"\n"'
| 100
