bash: ./myscript: No such file or directory. TMP variable is being unset

[Randall R Schulz]

Guy,

The fact that some shells fall back to treating files with execute 
permissions and no '#!' line as being suitable for execution by the 
standard system shell is really an artifact of a time long past. I humbly 
submit that you ought to use #! lines in all your "executable" scripts, 
even if they do operate in the way you intend on a bona fide Unix or Linux 
system.

You may have noticed that the synthesized execute permissions under Cygwin 
are keyed off of select file name extensions or the presence of '#!' as the 
first two characters of a file. I'd say Cygwin is bending over backward to 
create this degree of compatibility with Unix (-like) systems. There is 
little alternative since Windows file systems are impoverished as to 
explicit type information and access control attributes (as a Mac user and 
programmer I see file name suffixes as a very poor substitute for file type 
information).

Lastly, a quick (not thorough) check of the options and man page for BASH 
didn't reveal a way to enable the behavior you desire. Perhaps you could 
add such an option.
