Thanks for the script, I got curious, saved the instructions in a file
and run it either in bash or in tcsh shell, but always obtained the
following error 

adding 1

time: cannot run for: No such file or directory
Command exited with non-zero status 127
0.00user 0.00system 0:00.00elapsed ?%CPU (0avgtext+0avgdata 1224maxresident)k

./testbranching.sh: 11: ./testbranching.sh: cannot create : Directory nonexistent
./testbranching.sh: 11: ./testbranching.sh: arithmetic expression: expecting primary: "( / 2)"


So there is something I miss, but what?

Thanks
