Redirect to variable

MrAd · #1 (**permalink**) 05-07-2007

how do you redirect stdout into a variable. whenever I try I get an ambiguous redirect error

I am trying to validate some user input and failing miserably.

cal $MONTH $YEAR | grep -c "$DAY"

if the above is 1 then it is valid if 0 then not valid. I have been trying to redirect the output into a variable but get the error. Any ideas?

Many Thanks.

Try:

X=`cal $month $year |grep -c $day`

The ` character is usually the lower case of the ~ character, and is located just to the left of the '1' or above the tab key on most keyboards.

Or

cal $MONTH $YEAR | grep -c "$DAY" | read VAR1
