yup - i think a few years ago i did a hasty edit; it was originally 1024^2, but
i wanted fewer digits
what puzzles me is why the awk loop doesn't work when i issue the above command
directly in the shell - works fine as a script file

Re: Swap file tracking
Could it be a sleepimage ? On my Mini mid 2011 (running 10.6.8), there are two rather small swapfiles (67 MB each), and a huge sleepimage of 8.52 GB in private:var:vm Rudolf Am 04.12.2013 um 18.46 schrieb Neil Laubenthal: On Dec 4, 2013, at 12:41 PM, list boy i.am.list@gmail.com wrote: Anyone know if there's a way (via the console/Terminal) to track swap file size, over time?

i used to have this shell script assigned to a keyboard shortcut:
#!/bin/bash
ls -l /var/vm/swapfile* | awk '{ foo+= $5 } END { printf swap is %2.1f MB,
foo/1024^3 }' | growlnotify
you can get growlnotify from here:
http://growl.info/downloads
you could re-purpose this to send output to a log file
You can ls /private/var/vm of course…but I don’t think the actual size of the
swap files in there goes down unless you reboot in which case they get deleted.
they do go down, but not exactly proportion to memory you free up, and not
immediately
I thought I understood this stuff…but Activity Monitor shows 8.11 GB of VM
currently while I only have a 67MB and a 1GB actual swap file. Where does the
over almost 7GB of VM reside?
most of that VM is probably mapped to files on disk (other than the swap files)
or to memory shared with other processes (whether on disk or in RAM)
i believe it's also possible to allocate memory but never reference it and thus
have it exist as an address that is neither in RAM nor on disk

NB: You will *always* have at least 1GB swapfile under 10.9. (actually, I think you will have a 64MB file and a 1GB file at minimum). Where does the over almost 7GB of VM reside?

Where does the over almost 7GB of VM reside? In imaginary land... Most of this probably is memory mapped/reserved by some processes that never was used, so it's basically more imaginary than even virtual. I think these days the only sane way to deal with this is to stuff all the memory sticks into your machine that it can take and then never think about it again.

Re: Swap file tracking
Agreed, except I'm at 4 GB (which I believe was the max for a MacBook Air 4,2) And it seems like most people gasp when I tell them my swap file size(s). So maybe (?) my particular case has something especially wrong with it...

Re: Swap file tracking
10.7.5 definitely will reduce swapfile size when programs free up memory. Today, for example, I was at 8 GB of swap file, and now I'm down to 4 GB. Earlier versions would not; at least as recently as 10.4, and I think 10.5 on the PPC, swapfile space would only be reclaimed if everything after point X was free. It would not compress the swapfile, but instead relied on everything going away. Naturally, that didn't happen often. I consistently find that if I log out, and log back in, swap used is down to around 250 MB, yet for whatever reason, the swap files (there are more than 1) will never go below 1 GB of disk space. I agree, more memory is the answer. The better question is why; why not run happily in 16 MB inside a pizza box?___ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk
