piping output from shell process to transcript

Hi,

how can I pipe output from PipeableOSProcess to Transcript?

I tried doing:

(PipeableOSProcess command: 'my-command.sh') outputOn: Transcript.

However `#outputOn:` doesn't send `#endEntry` so I don't see anything,
and even if it would, the output is delivered there at the end anyway.

I would like to see the live result of the running commands.

Thanks,

Try this:

| p |

p:= (PipeableOSProcess waitForCommand: 'whoami').

Transcript show: (p output).

This will not do, as I said, I need live result. `#output` will output
it only after the process has completed.

This will not do, as I said, I need live result. `#output` will output

I can only suggest some of the code GitFileTree uses; with a delay loop to retrieve continuously the output.

Look at MCGitFileTreeRepository class >> #runOSProcessGitCommand:in: [https://github.com/dalehenrich/filetree/blob/pharo5.0_dev/repository/MonticelloFileTree-Git.package/MCFileTreeGitRepository.class/class/runOSProcessGitCommand.in..st]

It's a low-level use of OSProcess, but it is fairly reliable.
