prtconf

should help on Solaris and AIX. Search for "Memory" .

Under AIX

lsattr -El sys0 -a realmem

will also do.

HPUX:

grep -i physical /var/adm/syslog/syslog.log

or, if you have the Support Tools:

echo "selclass qualifier memory;info;wait;infolog"|cstm | grep "Total Configured Memory"

On Linux run

cat /proc/meminfo

and search for "MemTotal". Or issue "free" and see "Mem:" under "total".
