Method: LinuxStat::Kernel.compiler

Defined in:
lib/linux_stat/kernel.rb

.compiler ⇒ Object

Returns the compiler used to compile the Linux Kernel.

If the information isn’t available, it will return a frozen empty string.

The output is also cached (memoized) ; as changing the value in runtime is unexpected.
