Consider the interactive program interactive
. I have to run this program fairly frequently, and each time I run it the first few commands are the same. Obviously, having to type those commands over and over again is a pain. I have collected those command (separated by newlines) in the file cmd
. Now I can do cat cmd | interactive
to run the commands. The problem is that once cmd
has been fully read, interactive
recieves EOF and exits.
What I wish to do is first have interactive
read from the pipe (obviously interactive < cmd
is also acceptable) and when EOF is received, start reading from the keyboard instead.
