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 probably need to use one of the modules IPC::Open2, IPC::Open3, IPC::Run
or Expect.
