With all those connected with & won't it skip the rest after the first failure? Or does 'no such program' or 'you don't have permission' not produce an error?

In bash, & just starts the program in the background, so all of the commands are run in parallel. You're probably thinking of &&, which runs the command on its left, checks its return code, and then decides whether run the command on the right.

Although, in this case there are no 'commands on the right' since all the commands are on separate lines. You'd need to backslash the commands together, something like

pip install "$1" && \
easy_install "$1" && \
...

I saw it as wrapped, so couldn't dismiss the option that all were on a single logical line. But you're right, I was thinking of &&

[-] Tja@programming.dev 8 points 2 weeks ago

That would be &&.

A single & will run them in parallel.
