but what's wrong with a script?
oh, and you could just omit the 3rd part with the fancy braces; in this
case you would have to parse the line yourself, e.g. using
[route MemFree:]

i don't know, because yout linux command book cannot list each and every
tool possibly installed on one of the flavours of linux? (or unix?)

a good ressource for finding what's available is usually man/apropos.
% apropos free | grep -i memory
gives me 24 hits, among them "free (1)"

oh, btw, i think that the output of "cat /proc/meminfo" is easier to
parse than that of "free"....

yes, but it didn't happen 5 years ago when bush was president.
i guess it only happens since Obama became president.
