1. Use xpg4 "ps" with sz and vsz option
ps -o pid, sz, vsz, comm, args
sz => size in physical pages of process
vsz => size in KBs

2. Also you can use top
Check SIZE(total virtual size of the process in KB) and RES(resident
size of the process in KB)

3. General "ps"
# ps -efl

Check SZ(size of the process in pages)
