EDIT: Just look at the accepted answer. I wasn't how it worked at the time of writing so I just guessed below.

I am new to Linux so this might be a noob question. I am trying to install a new web browser called breach which is built in JavaScript specifically Node.js, and I wanted to try hacking on it a little bit.

I installed the tar folder from off of their site and I have a folder called AUTO_UPDATE_BUNDLE and a file called breach.sh I believe the breach file is a bash script and I was guessing that's how I install it. (I have no idea if that's correct though.)

So I looked up online how to run a bash script. I went in the terminal and this is what I wrote while in the directory of the breach.sh file.

sh breach

I got this error.

[3428:3428:0710/191300:858123323:FATAL:browser_main_loop.cc(172)] Running without the SUID sandbox! See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for more information on developing with the sandbox on.

Aborted (core dumped)

I then navigated to the link to code.google.com/... above and it said

We need a SUID helper binary to turn on the sandbox on Linux.

In most cases, you can run build/update-linux-sandbox.sh and it'll
install the proper sandbox for you in /usr/local/sbin and tell you to
update your .bashrc if needed.

I don't understand how I can run build/update-linux-sandbox.sh. Is build a directory in my root directory? I tried searching for it there but I couldn't find it.

I would appreciate any help, and if I'm heading the wrong direction with properly installing this browser than correct me where I am wrong. Thanks in advance.
