FreeNAS Shell vs Other SSH Programs

[Thousandbuckle]

Hello all, I have found that I can run a command through the FreeNAS shell in the webgui but doing the same command through Putty ssh connection to FreeNAS box I get error. What would be the reason for getting the different results from the Shell vs Other SSH programs? What is the best way to connect to FreeNAS box outside of using the built in shell?

The command I am issuing is the text below.

1. #! /bin/sh
2. echo "CPU temp :"
3. sysctl -a |egrep -E "cpu\.[0-9]+\.temp"
4. echo
5. echo "HDD temp :"
6. for i in $(sysctl -n kern.disks)
7. do
8. DevTemp=`smartctl -a /dev/$i | awk '/Temperature_Celsius/{print $0}' | awk '{print $10 "C"}'`
9. DevSerNum=`smartctl -a /dev/$i | awk '/Serial Number:/{print $0}' | awk '{print $3}'`
10. DevName=`smartctl -a /dev/$i | awk '/Device Model:/{print $0}' | awk '{print $3}'`
11. echo $i $DevTemp $DevSerNum $DevName
12. done

In the FreeNAS shell I get this result which seems to work properly:

[root@FreeNAS ~]# #! /bin/sh
[root@FreeNAS ~]# echo "CPU temp :"
CPU temp :
[root@FreeNAS ~]# sysctl -a |egrep -E "cpu\.[0-9]+\.temp"
dev.cpu.3.temperature: 42.0C
dev.cpu.2.temperature: 44.0C
dev.cpu.1.temperature: 43.0C
dev.cpu.0.temperature: 45.0C
[root@FreeNAS ~]# echo

[root@FreeNAS ~]# echo "HDD temp :"
HDD temp :
[root@FreeNAS ~]# for i in $(sysctl -n kern.disks)
> do
> DevTemp=`smartctl -a /dev/$i | awk '/Temperature_Celsius/{print $0}' | awk '{print $10 "C"}'`
> DevSerNum=`smartctl -a /dev/$i | awk '/Serial Number:/{print $0}' | awk '{print $3}'`
> DevName=`smartctl -a /dev/$i | awk '/Device Model:/{print $0}' | awk '{print $3}'`
> echo $i $DevTemp $DevSerNum $DevName
> done

If I use Putty SSH connection I get a partial success for CPU but for HD I get some kind of issue/error the red text below. If I hit enter it keeps scrolling pages of the numeric values in red listed below:

[root@FreeNAS] ~# #! /bin/sh

Looks like putty isn't letting you change shells (lines 1&2). What shell are you running (likely bash), and maybe whatever shell that is has a different syntax. I think echo $0 will tell you your configured shell.

I see one issue right off the bat

Code:

#! /bin/sh

Has a space after the #! that shouldn't be there. It should look like this:

Code:

#!/bin/sh

Also, how are you running this script? It looks like you are pasting it into the terminal instead of running like a script.

You are using a different shell. Put all of this in a script with a proper shebang that matches your script syntax.
