How to write into the STDIN an ASCII value?

[JohnLongHorn97]

Hello everyone,

I would like to write a script that will read several ascii characters directly into the STDIN, so it will be like I pressed these values in my keyboard, in another window.

for exemple, I will insert the ascii value of "tab" into the STDIN, and the focus will be changed in another window (let's say control panel..).

I thought I could simply write into the STDIN, but I haven't made it.
Here what I tried to do:

open (STDIN);

# The function is doing the action of an ASCII value
print STDIN "chr(9)";
system("start control panel");
close(STDIN);

I will be happy to read a solution...

thanks!

You can't write to STDIN. It's an input stream, not an output stream. You probably need to write it to a pipe, which gets passed to your command as STDIN. But I don't think that will help you - the only reason you want the tab is to change focus, so you aren't interacting with perl at that point, but the window manager...
