Getting an absolute value is pretty simple
# echo $a | tr -d -
or
# echo $a | sed 's/-//'

Can't believe google doesn't provide an answer, searched these
archives also!
#a=`expr 2 - 1`
#echo $a
1
#a=`expr 2 - 3`
#echo $a
-1
I want to get the absolute value of the difference. I don't
have to use expr, but also would prefer something available
directly with the Borne shell.
