If you save the following script in a file named obfuscate:
make it executable with:
and execute the command:
then the command:
will give you:
and the command:
will give you:
Is this what you're looking for? If won't work with characters that aren't in the 7-bit ASCII character set and it won't work if the text you want to obfuscate contains any NUL bytes, and on many systems it won't work if line in files you want to obfuscate are longer than LINE_MAX bytes and if the output produced by obfuscate produces a string longer than LINE_MAX, dc may not be able to decrypt it for you on some systems.
If you want to try this on a Solaris/SunOS system, change awk to /usr/xpg4/bin/awk.
The standards didn't require awk to treat a file name operand of - as a request to read standard input (although most implementations of awk already did this) until the 2013 editions of the POSIX Standards and the Single UNIX Specifications. If the implementation of awk on your system gives an diagnostic message similar to:
you'll need a two step process (or three step, if you remove the temp file when you're done) similar to:
to make it work.
If you want to see the dc commands awk created in obfuscate for the input you fed it, the command:
after running obfuscate will show you the input dc processed for the last invocation of obfuscate. For the above commands, that would be:
Are we having fun yet?

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.

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.

I am thinking of adding a new full manual inside AudioScope.sh.
A few questions here.
The main question is, assuming I go ahead with this idea:-
Is there a limit... (6 Replies)
I have users that print files to selected printers. Instead of creating one function for each printer I would like to have just one and passing the files to print as well as the wanted printer. The following code does not work, of course.
I'm expecting that $1 is the list of files to be printed... (6 Replies)
