How to disable command output in jenkins pipeline build logs

Question

I am using Jenkinsfile for scripting of a pipeline.

Is there any way to disable printing of executed shell commands in build logs?

Here is just a simple example of a jenkins pipeline:

node{   stage ("Example") {     sh('echo shellscript.sh arg1 arg2')     sh('echo shellscript.sh arg3 arg4')           } } 

which produces the following output in console log:

[Pipeline] node Running on master in /var/lib/jenkins/workspace/testpipeline [Pipeline] { [Pipeline] stage [Pipeline] { (Test) [Pipeline] sh [testpipeline] Running shell script + echo shellscript.sh arg1 arg2   shellscript.sh arg1 arg2 [Pipeline] sh [testpipeline] Running shell script + echo shellscript.sh arg3 arg4 shellscript.sh arg3 arg4 [Pipeline] } [Pipeline] // stage [Pipeline] } [Pipeline] // node [Pipeline] End of Pipeline Finished: SUCCESS 

Basically I would like to disable printing of the commands itself.

+ echo shellscript.sh arg1 arg2 + echo shellscript.sh arg3 arg4

By default Jenkins starts shell scripts with flags -xe. -x enables additional logging. -e makes the script exit if any command inside returns non-zero exit status. To reset a flag I'd suggest two options:

1. Call set +x in the body of your script.
2. Pass custom shebang line without -x: sh('#!/bin/sh -e\n' + 'echo shellscript.sh arg1 arg2')

As for the second option you can define a wrapper function for convenience which will prepend the script with custom shebang and then call sh

def mysh(cmd) {     sh('#!/bin/sh -e\n' + cmd) }
