Hi folks, I'm having trouble with a little shell script. Can somebody explain me why I get 3 times "expr: syntax error" in my console after I run this little script?
#! /usr/local/bin/bash # testscript var1="trees.J48" #other value will be rules.Jrip, rules.DecisionTable len=${#var1} ind=`expr index $var1 s` pos=`expr $len - $ind` out=`expr substr $var1 $ind $pos` I would expect (and want the following to happen): $ind should contain 6 $pos should contain 3 $out should contain J48 (other values will have to be Jrip,DecisionTable) Can anyone help me with this?
