Hi, I’m trying to use mender-artifact **cp** and **cat** commands using jenkins. The cat commands work fine but the cp command fails to execute. Here is output from the jenkins machine. //mender-convert - ls - bbb-convert-stage-2.sh - convert-stage-3.sh - convert-stage-4.sh - convert-stage-5.sh - device-image-shell - docker-build - docker-entrypoint.sh - Dockerfile - docker-mender-convert - files - input - LICENSE - LIC\_FILES\_CHKSUM.sha256 - mender-artifact - mender-convert - mender-convert-functions.sh - output - qemux86\_64-convert-stage-2.sh - README.md - rpi-convert-stage-2.sh - rpi-convert-stage-5.sh - ukey-update-artifact.sh 00:00:00.012 + sudo ./ukey-update-artifact.sh **no artifact or sdimage provided** _Contents of ukey-update-artifact.sh_ _./mender-artifact cat output/.mender:/etc/fstab **–\> This works** _ _./mender-artifact cp input/mender.conf output/.mender:/etc/fstab **–\> This fails -ERROR -(no artifact or sdimage provided)**_ _./mender-artifact rm output/:/etc/fstab --\> **This works** _ **NOTE** : When i manually run this script it works perfectly but it fails on jenkins ---

Hi, we stumbled across this issue ourselves just last week actually. The problem is that the scripts are fed through stdin on the machine, and mender-artifact (faulty), decides to read from stdin, instead of the two files which are listed on the command line. The PR with the fix can be found here: [https://github.com/mendersoftware/mender-artifact/pull/215](https://github.com/mendersoftware/mender-artifact/pull/215). Please note that the implementation now (with this PR), requires the use of ‘-’ explicitly, in order to read from stdin. ---

As a temporary workaround, you can reshape your command to: ```auto ./mender-artifact cp output/.mender:/etc/fstab < input/mender.conf ``` But please note that this workaround won’t work after this is fixed. Normally we don’t change behavior in minor releases, but I think we will make an exception here, due to the very confusing nature of this. ---

The following error comes after making the changes. **got 1 arguments, wants two** I guess **cp** command is taking the whole command as one argument. My command: **./mender-artifact cp ‘output/xyz.mender:/etc/fstab’ \< 'input/fstab’** ---

Can you please tell which file should i use with **cat**. For example I need to copy a file fstab with address **input/fstab** to the mender artifact in location **etc/fstab**. ---

Thank you soo much the command now works as expected…!!! The cp command now works and changes the .mender file ---

Hii everyone I am facing another issue. While I copy the files with the above-mentioned solution; I am getting permission issue with my files. I m modifying the mender-device-identity file with Jenkins and copying it inside the .mender file. Original mender-device-identity permissions : -rwxr-xr-x After deploying mender update to a Raspberry Pi3: -rw----- I tried changing the permission using the commamd: **./mender-artifact install -m 777 input/mender-device-identity $file.mender:/usr/share/mender/identity/mender-device-identity** But it came up with the same error as it was throwing in **cp command** **No artifact or sdimg provided** ---

Hi @Shrulabh, I don’t see anything wrong with your command at first sight. Have you tried this command locally? And are you sure that `$file` resolves to a filename, without the `.mender` extension? ---

Hii @oleorhagen yes the **$file** resolves a filename and the command works locally. But the issue is that it fails in Jenkins build; with the error **No artifact or sdimg provided** ---

Could you show me what `$file` resolves to? 🙂 ---

@oleorhagen **./mender-artifact install -m 777 input/mender-device-identity output/ras\_modify.mender:/usr/share/mender/identity/mender-device-identity** This is the final command that runs in jenkins ---

Hmm, curious, I don’t see anything wrong with it on the surface. Could you send me the artifact in question ? Also which version of mender-artifact are you using? ---

I’m using the prebuilt mender artifact that is mentioned in the documentation of mender. [https://d1b0l86ne08fsf.cloudfront.net/mender-artifact/3.0.1/mender-artifact](https://d1b0l86ne08fsf.cloudfront.net/mender-artifact/3.0.1/mender-artifact) this is the link
