Re: [PD] show "used or free system memoy" from within pd-extended (Ubuntu 8.04) -nogui - is this possible?
Thank you IOhannes,
is it possible to show "used or free system memoy" from within
pd-extended (Ubuntu 8.04) -nogui.
[shell]
I know I can use [shell] to communicate but I cannot find a command line
for
it. So the command is what I actually need.
ah i see. check the contents of /proc/meminfo
something like: % cat /proc/meminfo | egrep "^MemFree:" | awk '{print $2}' should do the trick (note that [shell] is not so good with such things; put the above (or better) command in a shellscript which you run using [shell])
I tried this. But as you mentioned without a script it doesn't work because pd doesn't seem to accept the "{" and "}" characters.
However by further searching the net I just found very simple command that works with [shell] "free". I don't know why this is not documented in my linux command book?
You are probably right about that. However my system freezes in such a
case
- no matter whether it's caused by pd or linux.
i do not doubt that. but why did you blame Pd then? it doesn't really matter whether it's caused by Obama or by linux either....
You're absolutely right about that. ... it's just that I'm running pd when it happens! :(

but what's wrong with a script? oh, and you could just omit the 3rd part with the fancy braces; in this case you would have to parse the line yourself, e.g. using [route MemFree:]

i don't know, because yout linux command book cannot list each and every tool possibly installed on one of the flavours of linux? (or unix?)
a good ressource for finding what's available is usually man/apropos. % apropos free | grep -i memory gives me 24 hits, among them "free (1)"
oh, btw, i think that the output of "cat /proc/meminfo" is easier to parse than that of "free"....

yes, but it didn't happen 5 years ago when bush was president. i guess it only happens since Obama became president.
