The closest I could find is memtop, a Python script available here on Google Code.

How to use memtop

• It's a Python script, so simply do a sudo mv memtop-1.0.0.py /usr/bin/memtop.py and a chmod +x /path/to/memtop.py to make it executable


• Default update period is 15 min; use switch -p 1 to make it 1 minute, etc. (can't go lower than that unless you modify the source)


• Use -l N, where N is the number of processes you want to show, depending on the size of your terminal.


• Use -m to show "more" information, i.e. the Swap/Page stats at the bottom of the screenshot.

The htop disguised as memtop option

If you don't use htop otherwise, it's pretty easy to set it up with the F2-setup option to look like memtop:

• htop config is stored in ~/.config/htop/htoprc, so just delete htoprc to restore normal htop.
