I think it may be possible to cygwin installed and not have it in the path,
if it's started from a bat or cmd that modifies the path etc...
anyway, finding cygwin1.dll may be a slow process. It might be better to
access the registry, this jscript uses the windows scripting host, so won't
work on older boxes unless wsh is there, but as a proof of concept it may be
ok.
---- start ----
// JScript.
var wsh = new ActiveXObject("WScript.Shell") ;
var KEY9X = "HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\" ;
var OsRoot = "?" ;
var CygRoot = "Cygwin Not Found" ;
try {
OsRoot = wsh.RegRead(KEY9X+"Version")
} catch(err) {}
if ( OsRoot != "?" ) { // Win9x or Me
cygkey = "This needs determining - I have no 9x box to test" ;
try {
CygRoot = wsh.RegRead(cygkey);
} catch(err) {}
}
else { // NT or 2000
var cygkey = "HKLM\\SOFTWARE\\Cygnus Solutions\\Cygwin\\mounts
v2\\/\\native";
try {
CygRoot = wsh.RegRead(cygkey);
} catch(err) {}
}
WScript.Echo(CygRoot);
---- end ----
when run it should give the foder mounted as '/'. It also won't work on a
9X/ME box as I don't know the registry key for that without digging.
When I get home I may have time to hack this together as a standalone, if
anyone is interested.
