Issue

• Can I run a ksh script in a pipeline step?
• Can I run a perl script in a pipeline step?

Environment

• CloudBees Jenkins Enterprise

Resolution

By default, the system default shell will be run. In a Shell Step, multiple lines are accepted. It is therefore possible to use an interpreter selector such as #!/bin/ksh or #!/usr/bin/perl.

KSH Example:

node {
    sh "#!/bin/ksh \n" +
       "echo \"Hello from \$SHELL\""
}

Perl Example:

node {
    sh "#!/usr/bin/perl \n" +
       "print \"Hello from \$SHELL\";"
}
