i wasnt sure whether to put this in programming because its a builtin shell command... or in applications because it can also be an external program called echo... so its here.
I was wonderin if youd share how you do that thing with echo

Code: Select all

% echo '[q]sa[ln0=aln128%Pln128/snlbx]sb25384035327623601753454966742snlbxq'|dc

to make messages.

I would like to post some sort of amusing message on my blog, but do not know how it is done.

It's actually quite complicated. It's not really a shell trick. All we are doing is sending a comand to the "dc" program (desk calc) via a pipe. The command we are sending is:

Code: Select all

[q]sa[ln0=aln128%Pln128/snlbx]sb25384035327623601753454966742snlbxq


I used to sign some of my messages with:

Code: Select all

$ echo '[q]sa[ln0=aln256%Pln256/snlbx]sb3135071790101768542287578439snlbxq'|dc


which I robbed straight from some of the old stupid UNIX tricks like found here: http://home.xnet.com/~dennis/unix_humor.html

Someone on MES came back with a different one that I hadn't seen before and I asked them how they did it because I had no idea myself. I believe the person's name was "perkilator" and he actually figured out all of the commands and how to create his own dc command to produce a hidden message. Here is the text file I threw together from his message that explains it so I wouldn't forget how to do it:
