Howdy,
I'm trying to extract the 1-minute loadavg in a portable (between RedHat
Linux and FreeBSD, at least) way without having to invoke a lot of
expensive subprocesses. On Linux, awk '{print \$1}' < /proc/loadavg
has been working nicely (though non-portably). When I log onto a BSD
host and my NFS-mounted home dir follows me, this obviously doesn't work
very well :-)
uptime | awk '{print $10}' works, but leaves a trailing comma. Adding a
sed statement to the end of that would start to get too expensive.
sysctl vm.loadavg | awk '{print $3}' works on FreeBSD, but isn't
portable back to Linux.
Anything else that simple and inexpensive that I'm missing?
TIA,
- Tillman
