what is the command to show virtual memory usage in the terminal? the one where it shows pageins/pageouts after an interval of say 't' secs.
thanks

Try typing that in the terminal and hitting the tab key.

vm_stats

It's just vm_stat actually, without that extra S at the end

But as macmike42 suggested - the Tab key is great if you just remember the first couple of characters in a command. Type those first characters and press Tab twice and it will show you commands available that begin with those characters. I use it all the time, but mainly because I'm too lazy to type the whole command through

For example, typing "vm_" and pressing Tab twice will complete the vm_stat command for you. Very nice!

vm_stats, that's it, thanks guys

btw, hitting the tab key hint is not consistent. i tried it by typing "to" or just "t" and it SHOULD show top right? but it doesnt.

ah.. just tried it again with 'upt' and it shows uptime
so i guess it requires a minimum of three characters.

oh, another question.. how can i make the terminal save commands that i type in so i can bring them back by hitting the up arrow. basically saving 'history of commands'. this was on by default in 10.1

No, it's becuase there is more than one result that starts with 'up' - there's update_prebinding, update-passwd etc. You have to press tab twice to see the full list.

Yes, it's actually quite simple. Check out the README in /usr/share/tcsh/examples. Basically, if you don't have a .tcshrc-file in your home directory, do this:

Code:
echo "source /usr/share/tcsh/examples/rc" > ~/.tcshrc

That will get your command-history working.

I know how frustating it can be when you know about a command but just can figure out what it is. One thing to do in a situation like that is to use the command apropos or whatis to search for keywords in man-pages.

Top shows the vm stats also. That's what I've always used.

Yes, but vm_stat shows more detailed information about your virtual memory. Running

Code:
 vm_stat 1

will for example give you updated information every second. Top works as well, but will not give you as extensive information as vm_stat.

Gosh, am I talking in circles? Maybe I need some sleep

Sarah31 · Apr 27, 2003, 05:59 PM

why ot save yourself some time and just alias commands that you will use frequently? i believe that is in the documentation too but essentally you would take a command suh as this:

cdrecord -v speed=16 dev=IODVDServices driveropts=burnfree -data /tmp/bacon.iso

and alias it to somethiung simple like 'burnd' with a line like this in your .tcshrc:

alias burnd="cdrecord -v......."

it is a simple way of not having to remember specific command and their options or for those lazy people like me that get tired of writing out huge command in the terminal. essentially you can almost hotkey all of your commands if you like (ie. vm_stat becomes vm).

the thing is, i had a file with all these commands explained but i lost the file either while installing 10.2 or switching over to my new PB
thanks for the tip tho.
