Re: ps_mem.py

What's in the black box? I can't see your image. All I get are ads when I allow javascript.

Re: ps_mem.py

But why use super-user rights to see how much RAM is used? I never understood the benefits of this program (ps_mem).

It displays the memory used for each process running, which can be very useful.

@OP: why not just post the text rather than an image of text?

Like this:

 Private  +   Shared  =  RAM used       Program

216.0 KiB +  71.5 KiB = 287.5 KiB       startx

Yes, I tried that before and after allowing javascript. It didn't work. I can never see twitter, either. Just a big blue bird. Maybe my computer is trying to protect me from what's there.

Whoa. To paraphrase the late rickh: Are you sure you're running devuan? That looks more like antix.

Oh yes, that's Devuan — I used the netinstall ASCII image then upgraded to beowulf and installed my simple-desktop package and switched to OpenRC.

It's running under 64-bit QEMU/KVM with 4GiB assigned and it runs very well indeed.

Re: ps_mem.py

Devuan lets me work my way up from scratch

I hear you on that.  It is my preferred way to build, not desktop install and then removing stuff.

Question, on my desktop, this ps_mem.py works fine.  But on another system I get this error.  Any ideas on what is missing?

$ sudo ps_mem.py
  File "/usr/local/sbin/ps_mem.py", line 448
    "%s: Shared memory is not reporte
                                    ^
SyntaxError: EOL while scanning string literal

The difference between the two systems is that the one that works is a desktop install.  The other is a virtual machine, devuan (ascii) on vultr.

Python is installed:

python is already the newest version (2.7.13-2).

Looks like vultr isn't exposing shared memory in it's containers but that's just an uninformed guess on my behalf.

Can you see /dev/shm in the output of df -h?

Re: ps_mem.py

So you don't have any shared memory in the container then.

Probably a good thing though, at least in respect of security.
