$ curl -L https://bit.ly/glances | /bin/bash That (curl|bash) is really shady. Not saying the software is malicious, but if you're going to install it I wouldn't do it like that.

Especially since you can actually detect server-side when its output is being piped to bash.

Earlier quoted context omitted.

Why is a pypi package better than a bash script? Or is it the URL shortener that concerns you?

Because a pypi package can be compared to a source. A piped bash script might change per-client or per-request.

This is the correct way to answer a question. Not sure why the parent question is being downvoted rather than simply being answered. All that does is promote ignorance.

There are OS packages for `glances` as well as `pip` packages.

No one should be installing anything from curl-to-shell pipelines - but sadly, they do.

Agreed, especially since there's a pypi package available.

And it's a bit weird to announce it as cross-platform (windows support) and not promote a cross-platform setup/install process.

And through a third party url shortener of all things?! There's no guarantee what'll come out the other side of a bit.ly link... At least leverage github directly, rather than add another level of indirection ...

Looking at the pointer: https://raw.githubusercontent.com/nicolargo/glancesautoinsta...

It doesn't even appear to support os x, installs via pip anyway (as root, unconditionally if you happen to have sudo credentials cached, or allow the script to elevate privileges).

This is probably never what you want, with the possible exception of a docker image, chroot/jail or similar.

And it really makes little sense to hard-depend on bash/sh for a cross-platform python utility - if pip install is too complicated, it shouldn't be too arduous to provide a sane python script for installation, that does most of this song and dance [and default to a virtual env] on all supported platforms. It's not like it can run without python, anyway...

Glances is a very sleek tool, but it comes at a cost: CPU usage.

As a ballpark measurement, running htop for 60s with a 3s refresh interval takes 0.2s of user time. Running glances (even with almost all modules plugins disabled) for the same amount of time takes 6.7s of user time.

I still use glances every now and then, but I don't leave it running like I might with htop
