Issue with assigning variables #45

Closed davesnx closed 7 years ago

davesnx commented 8 years ago 
parallelshell "echo 1" "ENV=3"

Hello, You can't declare variables, I guess that is because isn't a process (?). I'm not sure if it's an issue or not. The use case for that is you want to define some env variables at the same time of running a process. i.e.

NODE_ENV=dev node server.js

Edit: Reading the code I'm figuring out what's going on, the child-process spawn is throwing an error.

I think, this should work:

parallelshell "ENV=3 echo 1"
davesnx commented 8 years ago

@paulpflug isn't working, it's the same error. The spawn is reading ENV=3 as a command, If I have time I will open a PR with the fix

paulpflug commented 8 years ago

basically parallelshell does a sh -c "command" when I call sh -c "TEST=test env", TEST is there but sh -c "TEST=test echo $TEST" doesn't print anything

seems it is a problem of echo, maybe it computes its own env?

I don't think so... when u call sh -c "ENV" shows all the ENV of the system Also, when u run parallelshell "TEST=test"throws and error of sh If you run sh -a => Mark variables which are modified or created for export.

"TEST=test" should only work for the following command if you want to export to ENV then you have to use "export", but parallelshell doesn't support ENV exchange between different commands.
