I needed a tertiary way to compare executable/drivers, so a version number from windows seemed like a viable option. Hopefully someone will find this handy, seeing as i feel so guilty for not contributing more to such a wonderful project like Cygwin. And heck anything's better than that most recent dosshell thread :)

If I'm not mistaken there is at least one superfluous "echo $(" in
there.  I would also not use $@ since there could be multiple
arguments. IIRC you can also omit quotes around $(...) without risking
issues with multiple words.

finfo() {
  [ -f "$(cygpath -u "$1")" ] || { echo "bad file: $1" >&2; return 1; }

  wmic datafile where name=\"$(cygpath -w "$1" | sed 's/\\/\\\\/g')\"
get /value \
  | sed 's/\r//g;s/^M$//;/^$/d' \
  | awk '-F=' '{printf "%s=\033[1m%s\033[0m\n", $1, $2}'
}

Changed a few more things
 - error to stderr
 - line breaks
 - awk print -> printf

Unfortunately I don't have a cygwin handy to test this. I'd also
probably not output color coding control characters from this function
but rather use tputs to adjust to the terminal at hand. Also sed code
can be integrated into awk or replaced by dos2unix, I guess.

Kind regards

robert
