NAME
Rex::Commands::Gather - Hardware and Information gathering
DESCRIPTION
With this module you can gather hardware and software information.
All these functions will not be reported. These functions don't modify anything.
SYNOPSIS
operating_system_is("SuSE");EXPORTED FUNCTIONS
get_operating_system
Will return the current operating system name.
task "get-os", "server01", sub {
say get_operating_system();
};Aliased by operating_system().
operating_system
Alias for get_operating_system()
get_system_information
Will return a hash of all system information. These Information will be also used by the template function.
dump_system_information
This function dumps all known system information on stdout.
operating_system_is($string)
Will return 1 if the operating system is $string.
task "is_it_suse", "server01", sub {
if( operating_system_is("SuSE") ) {
say "This is a SuSE system.";
}
};operating_system_version()
Will return the os release number as an integer. For example, it will convert 5.10 to 510, 10.04 to 1004 or 6.0.3 to 603.
task "prepare", "server01", sub {
if( operating_system_version() >= 510 ) {
say "OS Release is higher or equal to 510";
}
};operating_system_release()
Will return the os release number as is.
network_interfaces
Return an HashRef of all the networkinterfaces and their configuration.
task "get_network_information", "server01", sub {
my $net_info = network_interfaces();
};You can iterate over the devices as follow
my $net_info = network_interfaces();
for my $dev ( keys %{ $net_info } ) {
say "$dev has the ip: " . $net_info->{$dev}->{"ip"} . " and the netmask: " . $net_info->{$dev}->{"netmask"};
}memory
Return an HashRef of all memory information.
task "get_memory_information", "server01", sub {
my $memory = memory();
say "Total: " . $memory->{"total"};
say "Free: " . $memory->{"free"};
say "Used: " . $memory->{"used"};
say "Cached: " . $memory->{"cached"};
say "Buffers: " . $memory->{"buffers"};
};is_freebsd

task "foo", "server1", "server2", sub {
if(is_freebsd) {
say "This is a freebsd system...";
}
else {
say "This is not a freebsd system...";
}
};is_redhat
task "foo", "server1", sub {
if(is_redhat) {
# do something on a redhat system (like RHEL, Fedora, CentOS, Scientific Linux
}
};is_fedora

if(is_fedora) {
# do something on a fedora system
}
};is_suse
task "foo", "server1", sub {
if(is_suse) {
# do something on a suse system
}
};is_mageia
task "foo", "server1", sub {
if(is_mageia) {
# do something on a mageia system (or other Mandriva followers)
}
};is_debian
task "foo", "server1", sub {
if(is_debian) {
# do something on a debian system
}
};is_alt
task "foo", "server1", sub {
if(is_alt) {
# do something on a ALT Linux system
}
};is_netbsd

task "foo", "server1", "server2", sub {
if(is_netbsd) {
say "This is a netbsd system...";
}
else {
say "This is not a netbsd system...";
}
};is_openbsd
Returns true if the target system is an OpenBSD.
task "foo", "server1", "server2", sub {
if(is_openbsd) {
say "This is an openbsd system...";
}
else {
say "This is not an openbsd system...";
}
};is_linux
Returns true if the target system is a Linux System.
task "prepare", "server1", "server2", sub {
if(is_linux) {
say "This is a linux system...";
}
else {
say "This is not a linux system...";
}
};is_bsd
Returns true if the target system is a BSD System.
task "prepare", "server1", "server2", sub {
if(is_bsd) {
say "This is a BSD system...";
}
else {

task "prepare", "server1", "server2", sub {
if(is_solaris) {
say "This is a Solaris system...";
}
