Re^2: How do I test if my Perl script was run using a login vs a non-login shell
in thread How do I test if my Perl script was run using a login vs a non-login shell
The difference is that this login shell will be installed on 600 odd servers with different operating systems and I don't want to manage compiling C code across different operating systems.
:) You'll notice my question came before my suggestion, it wasn't about my suggestion
Let me elaborate, what is the difference between using a login vs a non-login shell? What effect does it have upon the execution of a program? Does it set some variables?
I doubt the only effect is a dash in ARGV
You could probably examine some perlvar or some POSIX call, but you'd have to know more about what su does -- I don't know too much about su.
