Hi All, As a beginning, I successfully completed the single file update using mender in Raspberry PI board running with Ubuntu 18.04. Now I have another two things to do, 1. How to update a complete folder using mender ? 2. I would like to run a custom shell script as soon as the mender updated the new file. How to do that in mender using state scripting, I have read about the state scripting documentation and I have basic idea about the naming convention and the folder structure. But I would like to get the procedure to run a script here. Any help will be completely appreciable. As I am new to mender, wish to be part of this. ---

Hi all, As I am stuck in the state scripting part, expecting some help from the mender experts or people who already worked with mender. Regards Dipin ---

> How to update a complete folder using mender You can use the [Directory Update Module](https://hub.mender.io/t/directory/325) to deploy directory updates. There are usage instructions in that link. Note that you have to put the update module in the `/usr/share/mender/modules/v3` directory on the device before you can use them. > I would like to run a custom shell script as soon as the mender updated the new file. How to do that in mender using state scripting, I have read about the state scripting documentation and I have basic idea about the naming convention and the folder structure. But I would like to get the procedure to run a script here. Just specify `-s ArtifactInstall_Leave_50_myscript` when you make the artifact, and this script will execute after the install stage. You can replace `myscript` with whatever you want, and the contents can be whatever you want. If you use the artifact generation script for the Directory Update Module, then you can specify such options at the end, after a `--`. So for example: ```auto ./directory-artifact-gen -n ${ARTIFACT_NAME} -t ${DEVICE_TYPE} -d ${DEST_DIR} -o ${OUTPUT_PATH} ${FILE_TREE} -- -s ArtifactInstall_Leave_50_myscript ``` ---

Thanks for you help. I am getting an error like _./directory-artifact-gen: line 32: hash: mender-artifact: not found_. But I downloaded the latest mender artifact binary and located in _/usr/bin/_ folder of my computer. Please suggest to resolve this issue ---

Did you also make it executable? ```bash chmod ugo+x /usr/bin/mender-artifact ``` ---

Tried to run a script as per your suggestion. I could able to sucesfully create an artifact with my custom script. But the update fails. Attached the screenshot of the failure. My script name is _ArtifactInstall\_Leave\_50\_myscript_ ![Screenshot%20from%202019-10-31%2014-37-14](https://canada1.discourse-cdn.com/flex036/uploads/mender/original/1X/2d938ee272c9f5a1498dfcf5ffd5500fba6dc1e9.png). Any modifications required in the client side to run this script? ---

Are you able to execute the script manually, if you copy it over to the device? Again you will need to make it executable if it isn’t. What kind of script is it? Bash script? Maybe you can post it here, if it’s not sensitive. ---

I could able to execute the script manually from the server environment. If i make the artifact along with script, the new directory is not even updating in the device. Its an empty folder. The script is a small shell script. The content of the script is only _echo “Hello”_ for testing purpose. And while naming the script file it should be only _ArtifactInstall\_Leave\_50\_myscript_ or _ArtifactInstall\_Leave\_50\_myscript.sh_ ---

A couple of things to check: - Does the script contain the `#!/bin/sh` shebang at the top of the script? If is is `#!/bin/bash`, try changing it to `#!/bin/sh` - Are any of your filesystems mounted with the `noexec` option? What is the output from `mount`? The `.sh` extension makes no difference, the script should execute either way. ---

Thank you very much 😀 After changing to `#!/bin/sh` i could able to deploy the artifact without any error. But how can I verify that my script is running on the device. I am not able to see my script on the device actually ---

You cannot see it directly, because the script only exists while the update is being installed. But if the script leaves a trace somewhere (for example `touch /tmp/script-was-here`), you can look for it afterwards. ---

Thank you for your help… I created a folder using script, so that I can make sure the script is working. Tested the same here and it worked well ---
