How to execute a file via adb command line?

Question

I am trying to root my Motorola Xoom. Root checker pro currently tells me that "Executing this file can grant root access!" So I want to try that.

the file is located in system/bin and is called su.

I have gotten this far:

adb shell

cd system/bin

How do I execute the system/bin/su file via the adb command line?

have you tried simply to type su, followed by the Enter-key? Sounds pretty stupid, maybe, but that's how su works. No cd'ing, it's even in the $PATH. — Izzy, Commented Feb 18, 2014 at 22:16
I tried that and nothing happened... I'll say adb shell cd system/bin and once it says root@android:/system/bin # I type su and hit enter. then the following line will say "su" and that's about it, i'm back at my previous prompt root@android:/system/bin # ? — oliver_siegel, Commented Feb 18, 2014 at 22:35
If the prompt character is a # instead of a $ then the shell already has root access. The root at the start should have been a bit of a clue. — Dan Hulme, Commented Feb 18, 2014 at 22:38
Hm... Root Checker says "Root Access is not properly configured or was not granted". And both apps that I would like to use which require root (basically the only reason why I am trying to root) also don't work, saying I dont have root O_o — oliver_siegel, Commented Feb 18, 2014 at 22:44

A few suggestions (this is a shell so I'm guessing you have basic shell commands) one or all of these may work:

First try: sh su

Then: bash su

Then: ./su

If it has an extension give all the above commands a try with the extension of su

Also as a suggestion to see what commands are available just type: help

[EDIT]

since you mentioned not having root access try using the sudo command before su (and the above commands if needed)
