Hi all,
Hopefully someone here is much more clever than I am. I've run out of
ideas on how to cleanly convert this chunk of ksh to posix sh. This is
from a BB/Hobbit/Xymon monitoring script for ZFS. I'd really like to have
this working cleanly on FreeBSD without requiring any funky shells or
using any temporary files.
The following is supposed to be able to loop through the output of
multiple zpools reading one line at a time and each line item is set as a
variable:
/sbin/zpool list -H | while read name size used avail cap dedup health
altroot
do
# do interesting things here
done
Unfortunately you can't pipe through read in posix sh. You also can't use
process substitution: while read var1 var1 < <(/sbin/zpool list -H)
Any ideas are greatly appreciated. I know there's a python-based script
floating on github but I cant guarantee every server will have python on
it...
Source of script is here:
