Perl's system() function seems to be working great for simple commands
like 'pwd' , 'ls' that does not require user interaction. But when I
try to execute commands that require user input (eg, su or yum while not
on root), then it says 'standard in must be a tty' and fails.
Is this because Perl is not inheriting the standard input properly? Any
ideas on how I can fix it?
You can't run su except from a terminal. This is not part of Perl, it's
part of the security for su. There's no way around this.
If you want the program to access files not normally allowed by
permissions, you set the program's owner to grant access and set its
set-userid-on-execution bit (see `man chmod`). The program then runs as
it's owner userid rather than that of the person running it.
