it is hard to compare the memory-usage between linux and solaris, because both handle vmsize different. For linux it is the reserved memory plus the heap plus the shared libraries; that's the reason linux tells you that a simple bash- shell needs >100MB of RAM. For Solaris it is just the used space (and maybe the heap); so bash "needs" only 7MB here. If you like to know how many memory your task is "using" at the moment, RSS is a far better place to look (you have to subtract the shared libraries through). For details about the linux-memory-system see [1]. Sincerely, DaB. [1] http://bmaurer.blogspot.de/2006/03/memory-usage-with-smaps.html -- Userpage: [[:w:de:User:DaB.]] — PGP: 2B255885
