Run commands in a shell

[dylanratcliffe]

The command source currently runs commands without any shell, this means that things like shell builtins won't work (e.g. echo). It also means that the environment won't be loaded in the way that users expect and things like additions to the $PATH might be missing.

Commands should be run within a shell by default (bash on Linux and powershell on windows).

Questions

Should users be able to specify the shell?

Maybe, since each shell will need its own arguments though (especially on windows) this won't be able to be completely dynamic, probably more like an approved list

What options should be exposed around shell customisations?

• Working directory
• STDIN
• Environment variables (Make sure these are appended and that we don't remove any environment variables we might otherwise need)
• Timeout
• User to run as

Tasks

• Work out how Golang is going to deal with the encoding of the text that we return. Is this going to be a problem?
• Re-use a single powershell session rather than spawning new ones #19
