disable/hide logging of shell script content to console log

[Bhushan Kittur]

Hello Everyone,

I am using "Execute shell script on remote host using SSH" under Build section of the Job config with lines of shell script placed there.

And see all lines from the shell script are logged into Jenkins console log during job's execution. 

Ex:

tarted by user anonymous
[EnvInject] - Loading node environment variables.
Building in workspace ...
[EnvInject] - Executing scripts and injecting environment variables after the SCM step.

executing script:
target_env="dev"

var1=${target_env}

key="test123"
branchName=dev_feature1
startDeploy()

case "$var1" in

dev ) 

.

.

.

esac

 So is there a way to disable/hide shell script contents from logging into Jenkins console output of the job.

You can hide your output away from the script by redirecting the output to /dev/null but I think this the most you can do – the commands that you write will still be displayed.

Jenkins uses the shebang, by default

#!/bin/sh -xe

-x will prompt those verbose details, if you'd like to reset that you can set the default shebang in your shell build step with something like

#!/bin/sh -e

# add whatever you'd like to do

Cheers

Thanks for the response.

Tried with "#!/bin/sh -e". Still everything gets logged to console.

The suggested shebang works as expected, see the below details:

Execute shell step based on #!/bin/sh -e

#!/bin/sh -e

echo hi

echo world

Console Output:

[example] $ /bin/sh -e /tmp/hudson8709802188364684962.sh
hi
world

Execute shell step based the default shebang

echo bye

echo world

Console Output:

[example] $ /bin/sh -xe /tmp/hudson8136234464915657626.sh
+ echo bye
bye
+ echo world
world

If the above shebang doesn't fit your requirements, you might consider to use the approach suggested by Teichner Peter 

Cheers

Thanks Victor. 

I assume you are running the shell commands on the same host machine (local). Did you try running on remote host ?

Here is the screenshot of the config I tired.

Hi,

I am facing the same issue in Jenkins- Unable to suppress code being printed from the remote host. I could not find the solution from any blog. 

Can you please share the solution?   

[Sabari V L]

Well, I found the solution myself after googling it for a week. The issue is resolved in latest ssh plug-in version 2.6.1
