Re: how is cygstart different from cmd /c or how to have cygstart start 'inline'?

Got a program that starts under cygstart, but I'd
like to be able to start it without starting up the program
in a new window..so was trying cmd /c.

I compared env's and noted both PATH and TMP had been
converted back to the backslash using case, so I
did that manually:

if ((usecmd)); then
    export TMP=$(cygpath -w $TMP)
    my newpath=""
    my sep=""
    readarray -t pathar < <(echo -E "$PATH"|tr ":" "\n")
    for p in "${pathar[@]}"; do
        n=$(cygpath -w "$p")
        newpath="$newpath$sep$n"
        #echo -E "newpath=$newpath"
        sep=";"
    done
    export Path=$newpath
fi

But no luck in launching (cygstart case works):

cd "$ldir" && {
    if ((usecmd)); then
        'c:/windows/system32/cmd.exe' /c "$lpath" "${args[@]}"
    else
        cygstart "$lpath" "${args[@]}"
    fi
}


I use:
<file name="/usr/local/bin/cmd'>
#!/usr/bin/env bash
# Copyright (C) 2018, cygSimple
#   mailto:cygSimple@xxxxxxxxxxxxxxxxxxxxx
#   https://sourceforge.net/p/cygsimple
# File: cmd

`cygpath "$COMSPEC"` "$@"
</file>

and

<file name="/usr/local/bin/start">
#!/usr/bin/env bash
# Copyright (C) 2018, cygSimple
#   mailto:cygSimple@xxxxxxxxxxxxxxxxxxxxx
#   https://sourceforge.net/p/cygsimple
# File: start

cmd /c start `cygpath -w -- "${@//&/^&}"`
</file>

The file /usr/local/bin/start uses the file /usr/local/bin/cmd because of PATH.

I use another such file to start the Windows version of gvim.

<file name="/usr/local/bin/gvim">
#!/usr/bin/env bash
# Copyright (C) 2018, cygSimple
#   mailto:cygSimple@xxxxxxxxxxxxxxxxxxxxx
#   https://sourceforge.net/p/cygsimple
export PATH=/c/opt/vim/vim74:"$PATH"
start /c/opt/vim/vim74/gvim `cygpath -w -- "$@"` &
</file>


So what else does cygstart do that I might setup
before a "cmd /c"
to get the target to run?


Don't know.

Or anyway to have cygstart run the command with its output in the
current window?


A windows program will have a different console by default. A console program could can communicate to the same console as it is started in unless it uses pty (e.g. /c/windows/system32/ftp).
