After another look, it becomes obvious that the manpage is misleading, there is an unexpected "not" in there:
If the -o option is *not* specified… Either this should be clarified a bit, or maybe even rethought? I wonder whether the 'free -o' output is at all useful, given that it includes buffers/cache claimed but not necessarily used. This machine has been up for an hour with 87 processes, and there is no way that it can actually use 15.9Gb worth of buffers already. Maybe -o should drop the Mem: line and instead promote the "+/- buffers/cache" line to its place instead? -- .''`. martin f. krafft <madd...@d.o> Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduck http://vcs-pkg.org `- Debian - when you have better things to do than fixing systems
