Continuing the discussion from [Disable internet connection of specific echo device on fritz box via script](https://community.openhab.org/t/disable-internet-connection-of-specific-echo-device-on-fritz-box-via-script/91374):

Hi,  
I tried to change the userprofile with the command which you discribe. But I always get a arrow in the Log file.  
Herer are my source code

```auto
rule "echoesszimmeranaus"
when
	Item echoanaus changed
then
	createTimer(now) [|
		if (echoanaus.state == OFF) {
			executeCommandLine("/etc/openhab2/scripts/fritzboxprofile.sh 192.168.178.1 password filtprof1071 never", 5000)
		} else {
			executeCommandLine("/etc/openhab2/scripts/fritzboxprofile.sh 192.168.178.1 password filtprof1071 unlimited", 5000)
		}
	]
end

```

```auto
#!/bin/sh

challenge=$(curl -s "http://$1/login_sid.lua?username=admin" | grep -Po '(?<=<Challenge>).*?(?=</Challenge>)')
md5=$(echo -n ${challenge}"-"$2 | iconv -f ISO8859-1 -t UTF-16LE | md5sum -b | awk '{print substr($0,1,32)}') 
response="${challenge}-${md5}"
sid=$(curl -i -s -k -d "response=${response}&username=admin" "http://$1" | grep -Po -m 1 '(?<=sid=)[a-f\d]+' | tail -1)

curl -d "sid=${sid}&edit=$3&time=$4&budget=unlimited&apply=&page=kids_profileedit" "http://$1/data.lua" >/dev/null 2>&1

```

For the username I tried also a second which has admin rights.

This is the warning message at the log

```auto
[WARN] [lipse.smarthome.io.net.exec.ExecUtil] - Execution failed (Exit value: -559038737. Caused by java.io.IOException: Cannot run program "/etc/openhab2/scripts/fritzboxprofile.sh" (in directory "."): error=13, Permission denied)

```

Maybe anybody can help me?

Best Regards

ExecuteCommandLine syntax varies by openHAB version, so let’s clear that up first.

Do you get this message in case you add

```php
cd /tmp

```

between "#/bin/sh and the row that starts with “challenge=” ?

Hi,

did you check the owner and the permission of the file “fritzboxprofile.sh”? You can run “ls -l” in the directory of the file and post the output.

I had add sudo in the commando line

```auto
executeCommandLine("sudo /etc/openhab2/scripts/fritzboxprofile.sh password filtprof1071 never", 5000)

```

So I haven’t an Error on the Log but the userrights aren’t changing in the Fritzbox.  
I had made a special user in Fritzbox for chaging the userright. I hope this is correct

Still applies

You can also check for responses

```auto
var results = executeCommandLine( ... blah ... )
logInof ("test", "My exec returned " + results)

```

It looks like that the EXEC Binding isn’t installed.

```auto
Off sudo: /etc/openhab2/scripts/fritzboxprofile.sh: command not found
I use openhabe 2.5 and I can't install the EXEC Binding over Paper UI. Is there an additional way to install it

Sorry I thought that the Binding is installed. I Tried it and I didn't receive an error message in Log

```

- executeCommandLine is an action
- exec binding is a binding that needs to be installed
- executeCommandLine is not part of the exec binding
- according to your code snippets you use executeCommandLine which does not require the exec binding to be installed
- command not found means that a file / binary or shell script that is to be executed cannot be found
- as the shell script ( fritzboxprofile.sh ) is before the colon this should mean that your shell script is started to be executed but a command from inside of that shell script is not found
- you can use a PATH variable inside of the script and add all relevant directories to that environment variable
- alternatively you may always use full path to any executeable/script/command
- add debug output to your script that ‘every’ line creates output once the error message appears you should be able to identify which command is the root cause ( because you can see the debug output of the line before )

At first thank you for helping

You can add addtional rows to the script like:

```php
echo $challenge > /tmp/debug.txt
echo $md5 >> /tmp/debug.txt
echo $sid >> /tmp/debug.txt

```

they need to be added after the related variable is set.  
Output will be stored in directory /tmp in file debug.txt.

To see result of the last curl command

```php
>/dev/null

```

can be replaced with

```php
>>/tmp/debug.txt

```

Pay attention to \> versus \>\>. The first one creates/overwrites a file. The second one appends output to the end of the file.

Thank you very much for helping me
