POSIX::1003::OS - POSIX for the file-system
POSIX::1003::OS is a POSIX::1003::Module
use POSIX::1003::OS qw(uname TMP_MAX); my ($sys, $node, $rel, $version, $machine) = uname(); print TMP_MAX;
You may also need POSIX::1003::Pathconf.
Get the name of current operating system.
my ($sysname, $node, $release, $version, $machine) = uname();
Note that the actual meanings of the various fields are not that well standardized: do not expect any great portability. The
$sysname might be the name of the operating system, the
$nodename might be the name of the host, the
$release might be the (major) release number of the operating system, the
$version might be the (minor) release number of the operating system, and
$machine might be a hardware identifier. Maybe.
ARG_MAX Max bytes of args + env for exec NGROUPS_MAX OPEN_MAX Max # files that one process can have open TMP_MAX Min # of unique filenames generated by tmpnam
