shell program, check for interactive login

neolution · 2003-12-14 20:45:56

hey, i'm fairly new to *nix programming in general

i want fortune to run for users at login time,
however i can't just slap fortune into the .bashrc file b/c that will not provide sftp a 'clean' environment for the added output to a noninteractive session messes up ssh do to its unix like implementation of things

anyway my question is a simple one, how do i check for an interactive session, where there is a tty attached to the standard input, or however it makes sense to be said.

i picked up an o'reilly bash ebook through my library but haven't had a chance to read it yet, so an example code snippet would be helpful if possible

thanks for the help

That very question can be answered with :

tty -s && fortune

However, I'm not sure if this solves your problem, since sftp may actually provide a tty ... I simply don't have any experience with sftp.

and since you intend to read up, I can only encourage you to do so, and I won't give an explanation of the above, so you have something to read up ;-)
