If you wanna check memory in freebsd use this script.
download from my server or original server
fetch http://bsd.mynux.net/freebsd-memory.pl.txt
or
fetch http://www.cyberciti.biz/files/scripts/freebsd-memory.pl.txt
mv freebsd-memory.pl.txt /usr/local/bin/free
chmod +x /usr/local/bin/free

Other way is using Linux Style
# cd /usr/ports/sysutils/freecolor
# make install clean
To see memory details, enter:
$ freecolor -m -o
Sample output:
total used free shared buffers cached
Mem: 4082 825 3256 0 0 117
Swap: 2048 0 2047
$ freecolor -t -m -o
Sample output:
total used free shared buffers cached
Mem: 4082 825 3256 0 0 117
Swap: 2048 0 2047
Total: 6130 = ( 826 (used) + 5421 (free))
