About runInShell

[busslina]

Hi, I wanted to know what runInShell parameter means.

Thanks.

process_run uses Proces io that has this parameter:
https://api.dart.dev/dart-io/Process/start.html

According to the doc:

If runInShell is true, the process will be spawned through a system shell. On Linux and OS X, /bin/sh is used, while %WINDIR%\system32\cmd.exe is used on Windows.

Thanks very much. It's a bit messy to have a Shell which defaults to false (true on Windows) runInShell. So if I understood correctly, when false, it's executed on the dart process.

Indeed it is kind of misnamed but i don't think it is safe to change the behavior now. I have not played much with this flag so I guess most of the times it is not needed. If someone has a good example that could explain cases when it is needed, I would gladly add it to the documentation.

Make sense. Now, an improvement would be to be able to select what shell. If sh is the default would be great to be able to use bash instead.

Edit: But this is not in the scope of this package I suppose.

Thanks for digging the proper doc @busslina
Indeed I added this parameter since it was present in the io version but I don't do much about it and my fear is that we cannot change the behavior. An alternative is to set it to false and use the preferred system shell.

Example on linux:

await run('bash -c uname');
