Linux - get shared memory values from Perl script

Question

I'm trying to get shared memory information from a linux box. I'm looking for shmmax, shmmni, shmall, msgmax, msgmni, semmsl, semmns etc. How to get all those values from a Perl script. any help is appreciated?

Answer 1

Would sysctl -a|fgrep shm or ipcs -l satisfy your knowledge appetite as starting points?

Answer 2

Using Tie::Sysctl, you could probably (I didn't test it) use something along

use Tie::Sysctl;

tie %t, 'Tie::Sysctl';
print "shmmax: ".$t{kernel}{shmmax};

etc, mildly sugaring plain /proc/sys reads.
