A memory usage utility for MacOS X Author: David Cantrell <david.l.cantrell@gmail.com> See COPYING.LIB for licensing details. http://code.google.com/p/darwin-free/ HOMEBREW: A Homebrew formula is available at https://github.com/nickolasburr/homebrew-pfa. To install via Homebrew, run the following: brew tap nickolasburr/pfa brew install darwin-free COMPILATION: You need a compiler, some headers, and a Mach-based system. On Darwin, you can type make: make And out will pop a 'free' executable. On other systems, it may require modification of the Makefile and/or source. INSTALLATION: Either run 'make install' or put the free executable in a public place and the man page in a sensible place. USAGE: See free(1). NOTES: This utility is designed to act like 'free' on Linux systems. It is a tool for displaying memory usage statistics. Since the Mach microkernel design is different than Linux, the values reported are not an exact duplicate of what you can get from a Linux system. Be sure to read the man page for an explanation of the program output.
