I have a bash to math calucations. It works but also complains about the
last line, even though it works.
Any ideas how to fix the problem or at least not see the error message and
still work.
#!/bin/bash
if [$1 == '']; then
echo ''
echo "format is $0 'math equation'"
echo "i.e. $0 (2+2)*3"
echo ''
exit
fi
echo $1 | /usr/bin/bc -l &2>/dev/null
unfortunately '&2>/dev/null has an additional problem.
