Why can't I pass these parameters to my command?

B=master U='[email protected]' curl -u "${U}" "https://bitbucket.org/myteam/pod-dev/raw/${B}/install.bash"

I get asked: 

Enter host password for user '':

See, the "U" is missing.

And also curl is performed:

GET /myteam/pod-dev/raw//install.bash HTTP/1.1

Also here, the B is missing (branch)

macOS Sierra 10.12.2

Variables assignments like you are using them are part of the command. In your case the shell will try to expand "${A}", "${B}" before they have been actually set - during parsing the command.

You can separate the variable assignments and the actual command by ;:

B=master; U='[email protected]'; curl -u "${U}" "https://bitbucket.org/myteam/pod-dev/raw/${B}/install.bash"

That way they are 3 separate commands.

Try like this instead of your command:

export B=master; export U='[email protected]' ; curl -u "$U" "https://bitbucket.org/myteam/pod-dev/raw/$B/install.bash"

bash will try to expand the variables first, but you haven't set them at this point. See for example:

$ x=foo echo "$x"
>

$ x=foo; echo "$x"
> foo
