output:

  • According to https://stackoverflow.com/q/34820975, the output of "git clone" is written to stderr, not stdout. – Martin R Nov 21 '17 at 09:21
  • @MartinR thank, I change FileHandle `process.standardInput = inputPipe;let fileHandle = inputPipe.fileHandleForWriting`,but look like useless – Karim Nov 21 '17 at 09:31
  • Unless I am mistaken, you have to grab `process.standardError` instead of `process.standardOutput` – Martin R Nov 21 '17 at 09:32
  • @MartinR `process.standardError` catch `Cloning into 'Masonry'...` but can't catch other,sorry,maybe I am mistaken other – Karim Nov 22 '17 at 01:21
