in reply to Parallel running the process

Hi,
I recommend you using pdsh
In your case should be:
  • modify your script to receive only database name as parameter (and to make only the work needed to that database), databases file contains line by line all the databases
  • $ pdsh -w^databases -R exec perl-script %h | tee outputs
  • then play with outputs (see dshbak), probably with an script which recollect the info
I hope that help

[tye]: That's funny, saying getlogin() is less secure. For some uses, it is far superior to getpwuid(), precisely for reasons of security.
[LanX]: search strategy => Perl Functions by Category
[Corion]: ... I found discussion of the who utility and that it uses the POSIX 2008 getlogin function (but that function was available much earlier and thus even exists in Perl, as a search for getlogin on CPAN brought up Perl 5.26 as first hit
[tye]: oh, LanX, but I was thinking that it was not a function that Perl provided.
[Corion]: Yeah, I also went a more roundabout way, just to find that the solution had been with Perl all along! ;)
[tye]: perhaps the "less secure" comment was motivated by old versions of getlogin() and trolled through the 'last' log trying to match your TTY. On modern Unix, I believe getlogin() just returns a fundamental bit of identity from your process.
[tye]: (Because every thing you do has that tag available for auditd.)
[tye]: Though it is certainly true that you should not use getlogin() for auth().
[LanX]: tye: just a tip for the next time, I found interesting things there...
