[oiskuu]: ... getlogin refers to tty owner; if you close STDIN, then getlogin returns undef. I get undef in my shell (running under X)
[tye]: Then there is a more persistent big of data similar to getlogin(). I don't believe even daemonizing drops it. So you can tell services that were started at boot time from those started by a person.
[tye]: I'll have to look into that later. getlogin() suites my current needs.
