Do spaces matter with expr?
Dec 11 2010 | 9:41 pm
Hello,
I was recently explaining expr to someone and told him that the spaces between the arguments in the expression didn't matter--meaning there can be white space like this:
$i1 + $i2 * $i3
or not like this:
$i1+$i2*$i3
It seems to work both ways, but I can't see any definitive statement on spaces in expr.
Does anyone know if the spaces or lack thereof ever become an issue?
