How to get return value from C program and logs to file
Hi, I have written scritp which prints output from the executable to standard output as well as in a file. Here "add" is an c executable which returns
some value based on inputs.
But if tee is not used "$?" returns the return value from add exe.
If tee is used it is simply retuning 0.
echo "Running program output"
myLine="./add 1 11"
`expr "$myLine"`| tee outputfile
echo "Succ/Fail : $?"
