Is there a way to run a.sh like in Case 1 and get the
proper result like in Case 2?
It sounds like your scripts are banking on the assumption that under
linux, sh=bash, whereas on Cygwin sh=ash. So, you can't get away with
using bash-isms in scripts without shebangs because you are relying on a
specific quirk of linux. If you require bash-specific features you need
to either call bash explicitly in the shebang or exec the script from
bash. Otherwise your script is not going to be portable on any system
other than linux. bash != sh.
