Assume I have this command:
./clang-$j.out >> clang-result.txt and the each output for
clang-$j.out is a fixed-length hash value (each program per line), however, I want to distinguish them by adding a prefix to the beginning of each line. For example, I want to add
"1-" where is number comes from the variable
I've made some effort to do this but I still cannot figure out how to do.
