Re: Use of SHELL env var by login

Greetings, Linda Walsh!

Do note I didn't mention any specific variable names.
Indeed -- wanted to be explicit for those not know that the space
in-between the lines is important! ;-)

And I've explicitly outlined exactly the case you are describing in your post
- integration.
If you indeed have "more other" applications (native ports of certain tools,
which still use environment as a go-to reference sources), then by all means,
do what you find best for you.
I do that all the time, too, but I also have Cygwin itself configured to match
the environment I expect to have. Just to avoid issues.
	Yup -- I use the same site-wide login scripts (for me & root and
multi-machine) on linux and cygwin and regularly make sure to copy and test
them on both -- not to mean I don't have cygwin specific sections that
key off OS:
if ! type -f cygwin 2>/dev/null ; then read SYSTEM_KERNEL HOSTNAME OSTYPE <<<"$($_prg_uname -sno)"
   if [[ $OSTYPE =~ Cygwin ]]; then sub cygwin () { return 0; }
   else sub cygwin () { return 1; }
   export -f cygwin
# and some cygwin-only defs in /etc/local/cygwin, like
alias gvim='setsid gvim'              # ensure win-native vim backgrounds properly

and a version of "mklink" that runs in bash and uses the
*nix syntax of "mklink <from> <to>" (and auto-handles directories)
