Shell Programming and Scripting

hi.

i´m working in bash and am trying to create a Perl daemon that controls bash´s behavior. this is actually in preparation for a later project i´ll be working on.

basically, i´m looking for a way to have the Perl daemon tell bash what to do. i already have a small daemon that simply prints to the screen after a given interval, but what i want to happen ideally is: say the user inputs ¨cd library¨ and hits enter, the Perl daemon should see that the directory is library, and subsequently tell bash to echo a few statements informing the user of what the directory is all about.

any tips? of course once this is done, this would open the doors to a great number of other possibilities. i´m just trying to take this first step.

thanks a lot everyone.

no one?

i just need a way to execute bash commands from Perl, such that when Perl reads a bash environment variable, it can tell bash to echo something, for example.

check out shell and exec.
