Howto store available drive space to a variable for script evaluation
Question: How can I capture available diskspace information in a script and depending on the value perform actions?
Ideally I'd like a working example of the following pseudo-code:
Set AvailSpace = awk/sed/parse and store to var number
if $AvailSpace > 333800 then
echo OK
else
echo abort
endif
Some jobs are failing due to insufficient drivespace.
This is an old process running on an old box with operating system of:
SunOS Release 4.1.3
I've got a partial clue on how to manually see the value:
JoeUser/usr/local% df | tail -1
/dev/sd2a 963662 581656 333823 64% /work
I'm just not sure how to assign the value '333823' to a variable for
comparison.
Any thoughts would be appreciated.
Thanks!

Thanks! Exactly what I was looking for. Now I know a little more about awk. Should help in some other areas.
FREESPACE=`df -k | grep device-name | awk '{print $4}'`
if you want to use device-name a command line arg, using $1 instead of the device-name.
Cheers!
