This question came from our site for system and network administrators.

Why on earth would you want to do that? The website may just change that script to read "rm -rf *" or worse. – Grant Aug 9 '13 at 18:23
@Grant Because I can store a bunch of scripts on my web server and have access to them anywhere whenever I need them without having to download them or carry them around on a USB stick. – Ben Aug 9 '13 at 18:25
You have to download them. That's what getting the data from the server is. – Etan Reisner Aug 9 '13 at 18:34

If you wrote the script -- meaning that you're absolutely certain you know what it does -- you can just do this:

curl -s | sh

That uses curl to fetch the script and pipe it to the Bourne shell. But in general, for anything you didn't actually write yourself, you should do what Grant suggested and read it first, because this is a great way to accidentally run malicious code.

So while this does, of course, "download" the script, it simply sends the data through the pipe rather than saving it to a file.

Then read the script to ensure it doesn't do anything malicious.

Then chmod +x and ./

Or just sh without bothering with permissions. – larsks Aug 9 '13 at 18:39
Yes assuming they are all sh scripts. Some could require other interpreters. – Grant Aug 9 '13 at 18:53
