in reply to Iterative HOH or AOH?

You have a few choices.

  • Give all your variables default values each time you enter the for-loop; and reassign if the corresponding hash keys exist;
  • Or assign each variable the corresponding hash value or some default value (e.g., $version = (exists $sw{$product}{'ProductVersion'}{'version'} ? $sw{$product}{'ProductVersion'}{'version'} : 0););
  • Or use a similar construct when printing (e.g., print "Version: " . ($version ? $version : 0););
  • Or, turn off the warnings with no warnings 'uninitialized';.

[oiskuu]: Hm. that depends on kernel compiled with CONFIG_AUDITSYSCAL L
[tye]: apropos my several mentions of audit
[Corion]: At least my (non-SELinux) Debian has that config thing set. I don't have non-Debian machines handy (except Android)
[Corion]: My Android phone also has /proc/self/ loginuid, but that displays -1 (resp. 4GB). That might be because the phone is rooted.
[tye]: -1 means nobody logged in or the process was started before audit got booted
[davido]: ok, on my ubuntu system getlogin grabs from /proc/self/ loginuid (per strace)
