Hello,
I'm attemping to use the expr variable and am having problems. when I
type test=expr 1+1 or
test=`expr 1+1` or
test='expr 1 + 1' or
with and without quotes?? I just want to create a variable based on
and expression?
(1) You didn't really describe what problems you're seeing (I think I
know what they are, though).
(2) expr wants separate arguments, like "expr 1 + 1", not "expr 1+1".
(3) use backtics to get the output when you set the variable:
"test=`expr 1 + 1`", not "test='expr 1 + 1'".
(4) This isn't really Cygwin-specific, so it would be better to try "man
expr" (for how to use expr) or "man bash" (for quoting rules).
Hope this helps!
I tryed it your way and it worked as well thanks again!
