Actually...While this owrks...it is not the "Standard" way that
I have seen. It seems nmore common to make the shell
/bin/false
This is an executable (/dev/null is not and gives a permission denied error)
and is an executable which just exits (retuyrning a value nonetheless but
still just exiting)..or form the man page:
---man false---
FALSE(1) FALSE(1)
NAME
false - do nothing, unsuccessfully
SYNOPSIS
false
false {--help,--version}
---done---
this is wrong for debina tho...I just tried it...neither option works
of course...you could make their login shell /usr/bin/yes (or a wrapper that
runs /usr/bin/yes "Go AWAY!"
