i generally use:
psql -A -t -q -d database -c "sql query" > tempfile
if [ $? -ne 0 ] ; then
echo command failed
exit
fi
awk -F\| -f script.awk tempfile
.....
there is a commandline options somewhere to change he field seperator, but
i forget it now.
you could do it all in one line and pipe the psql into awk/whatever.
but i've found that checking the return status of psql before actually using
the data is a useful thing. 8^)
