How do you pass commands to a cygwin console in Windows using Inno Setup

Question

I've tried variations of this, but had no luck other than the ability to start a cygwin window. (wrapped on ; for clarity)

Filename: "c:\cygwin\bin\bash.exe";
  Parameters: "-c c:/scripts/step1.sh paramX";
  Flags: shellexec waituntilterminated;
  StatusMsg: "Running the script..."

(this is for an internal install, thus cywin is installed, and all paths, scripts are known)

Answer 1

I think you're going to need to make the whole thing part of a cmd.exe invocation, and then I'm not sure it will do exactly what you want/need.

I'm looking at Inno-Setup 5 documentation (may be out-of-date), but I don't think you need the shellexec or waituntilterminated flags.

Try something like

Filename: "cmd.exe"; Parameters: "/c c:\cygwin\bin\bash -c 'c:/scripts/step1.sh paramx'"

Untested, caveat emptor.
