Question Automating interactive scripts

Hi all,
I am trying to write a program that will automate interactive scripts that use 'pkgadd'. Easily enough I can use 'pkgask' and a response file for most of what I want to do, but unfortunately there are parts of some pkg installations that are configured to only take input from /dev/tty!! Does anyone have any ideas on how I can get around the /dev/tty problem so I can automate it?

You can automate input to terminal by using a series of echo and sleep commands.....(sleep commands are important if some of the commands take time to complete).

Here is an exerpt from a telnet script I wrote that requires terminal input....


(
sleep 2
echo ${FTPid}
sleep 2
echo ${FTPpwd}
sleep 2
echo ${FINDstatement}
sleep 5
exit
) | telnet ${FTPserver}

The cariables are obviously all defined earlier..... so effectively my script is compelting the following commands to terminal

telnet <server>
user_id
password
command (i.e rm *.log)
exit

And there is sleeping between commands to allow the commands to execute before I type type the next. This should allow you to complete what you need.

Suppose we want to sort a huge collection of 1 trillion, 10^12, elements. Doing so with Selection Sort or Insertion Sort would require about n^2 = (10^12)^2 = 10^24 or 1 sextillion comparisons.
True or False?
