Hmm another example of daft Posix ideas.
To my mind the "-o" and "-a" syntax is easier to follow - expecially when bracketed for clarity. However if you happen to be a "C language" programmer you may disagree.

But ... a "case" statement may take more time to type but is a much more readable for the next person to read your script.

echo "i am in N"

else
echo "i am in Y"

You need spaces around the square brackets and you need weak quotes around the variables. Try this:
Code:
if [ "$connect" = n -o "$connect" = N -o "$connect" = no -o "$connect" = No -o "$connect" = NO ]; then

or preferrably this:
Code:
if [ "$connect" = n ]||[ "$connect" = N ]||[ "$connect" = no ]||[ "$connect" = No ]||[ "$connect" = NO ]; then

I would use a case statement;
Code:
case $connect in
  n|N|no|No|NO)
    echo "i am in N" ;;
  *)
    echo "i am in Y" ;;
esac

@Scrutinizer In both cases the above syntax will only work with bash.
In unix "Posix" shells there is no "==" operator.
I agree that the "case" solution is the best.

You are right Smilie, I overlooked the double == . It should be single = everywhere... I corrected my post...
