Hello everyone, I have a small issue that bugs me a bit in my day-to-day stuff.
At work I always keep a top command running on the crunching machine. It has around 32 gigs of ram, so I always use the "-M" option to display the used memory in megabytes (it runs some form of redhat I believe). However, on my home computer running Arch there is no -M option! The only difference I can find is that arch uses top v2.8 and redhat uses v2.7
So should I downgrade? That seems a bit silly for such a simple option...

Seems you're right, no -M here.
But I do get
2897 karol 20 0 370m 190m 24m S 2.0 19.2 15:57.50 firefoxso this only affects the total memory used.
Edit: do you need a list of processes or just the totals? If the latter, there's 'free -m'.

Yes, the individual processes do get rounded off. I know about free, but I just want to be able to keep track of the total free memory in mb without having to type "free -m" everytime.

Looks like a job for 'watch'!

Wow, didn't know that command! That will be useful elsewhere as well, thanks.

You can get the memory info from <drum-roll> /proc/meminfo.
less /proc/meminfoOffline
I've always prefered using htop as a direct replacement to top. It shows mbs used by default and has more features.

At times you don't want features.
To each his own.
