UNIX fun stuff - echo and dc - obfuscate/garble a string sort of
Hi,
Humorous UNIX Commands shows a fun way of using echo and dc to sort of obfuscate a string.
Code:
% echo '[q]sa[ln0=aln256%Pln256/snlbx]sb3135071790101768542287578439snlbxq'|dc
GET A LIFE!
I am just wanting to know if there is a way to sort of use dc and echo to print out an obfuscated/garbled string instead kinda doing the reverse of echo | dc? Should it be dc 'GET A LIFE!' | echo, that does not seem to be the way to it
So I want to be able to get the echo'ed string instead. I am trying to see if I can use this as some way of sending out a 'secret' message or password to a script or to a user so that when I reset their password, I'll just get them to do echo '<string>' | dc instead of sending them the plaintext password.
Hi,
My script prints a few varibales as each it reads each line of a text file and then prints them on screen, however iam having problem in aligning and sorting them.
what happens is this

Hi all,
I've search the forums regarding posts similar to this already but can't find the suitable response. Am actually looking for something very trivial I think.

Hi,
I need to somehow pipe the password to a command and run some SQL, for example, something like echo $password | sqlplus -s system @query01.sql
To make it not so obvious, I decided to try out writing a small C program that basically just do echo $password. So now I just do x9.out | sqlplus... (8 Replies)
Hi guys, man bash doesn't help much here nor does the WWW.
