Right. Topped.
But there is a big problem with that solution anyway: It assumes
that MemTotal is the first line in /proc/meminfo. If one decides
to reorder this table in the kernel or add some headline all your
scripts using this solution will break.
Surely. It was just a sports exercise.
If I would need it, I would do
grep ^MemTotal /proc/meminfo | (read a b c; echo $b )
and here bash needs the "(...)" to force the subprocess forking at
the right point...
No, it does *not* need a subprocess. You just need to expand the
pipe ;-)
grep ^MemTotal /proc/meminfo | { read a b c; echo $b ; }
Topped again :-)
Not really; the top solution does not call ANY external program.
If you (or other readers) want an explanation about expanding the
subshell or even need to "export" variables from subshells, have a look
at my homepage [1]:

Thanks; but just bookmarked now - too late tonight.
Oh, there's another way ;-)
set -- `grep ^MemTotal /proc/meminfo` ; echo $2
This time, I topped myself ;-)
Just using bash intrinsics is the skill.
Anybody out there who wants to top one of my solutions? *eg*
BTW: Christoph just told me that he is really upset about the
ignorance of all the readers here. He had done all his best to cat a
good MemTotal value from a real system, but noone did realize it...
Now as you mention it - "MemTotal: 526525152 kB" (500 GB) is something
I'd like to have ;-) (even all machines I have here together don't
have that much _hard disk_ space...)
You know, a man's ram size is directly proportional to the size
of his ...
Or was that reverse proportional?
