Is NSPipe suitable for wrapping interactive commands, eg. sftp? If not, is there something that is?

NSPipe can be used for that sort of thing, I think, but it's not always exactly simple. I've tried a couple of times to make a wrapper for ftp, and capturing stdout right is tricky for some reason. It keeps not wanting to print to stdout until it terminates, and then it has trouble printing file listings of more than a few lines. I think this is the sort of thing NSPipes are for, though, so I assume I'm just not doing something right. I'll have to go over my code later to see if I can find out what's going wrong.

Anyway, sorry for not being especially helpful. I don't know that much about them, but I figured any response would probably be more informative than none.

The problem with FTP might lie in the environment rather than in NSPipe. Some terminal applications query the terminal (stdout) for its dimensions before writing out to it. Since you're supplying a pipe, rather than a terminal connection (tty and its ilk), FTP may have no idea how big the output "screen" is. There are usually some environment variables that are used to make such determinations, first is the TERM variable which can be used to tell what kind of terminal emulation is supported, and secondly are the ROWS and COLS (I think that's what their called) variables that store the dimension of the terminal. I hope this helps as a starting point for solving your problem.
