CYGWIN_NT-5.2-WOW64 sds 1.7.9(0.237/5/3) 2011-03-29 10:10 i686 Cygwin
BASH_VERSION='4.1.10(4)-release'
at the bash prompt I observe this:
$ f(){ echo a=$a b=$b c=$c ; }
$ unset a b c
$ a=a b=b f
a=a b=b c=
$ f
a= b= c=
which I believe is correct (i.e., variables set in "a=a b=b f" are unset
after f terminates).
alas, when I call /bin/sh on the same machine, I see this:
f(){ echo a=$a b=$b c=$c ; }
f
a= b= c=
a=a b=b f
a=a b=b c=
f
a=a b=b c=
exit
i.e., variables set in "a=a b=b f" survive to the next command.
$ /bin/sh --version
GNU bash, version 4.1.10(4)-release (i686-pc-cygwin)
is this the expected behavior?
thanks.
