Running custom scripts

How to enter and run a custom script

1. Use one of the following two command templates depending on your server OS:

   • RunShellScript (Linux)
   • RunPowerShellScript (Windows)

2. Enter your custom script in the Script field of the pop up window on the right. The maximum length of your script content is 10.000 characters. You can also use the expanded script overview button for better code readability.

3. Enter the arguments, if any. Separate multiple arguments with blank characters.

4. Press Run.

Types of shell scripts that can be executed on Linux

For Linux there are different ways to execute a shell script depending on whether an argument and/or a shebang header is present.

Script with shebang header and arguments

A script with both shebang header and arguments will be executed as bash script.

Example script:

#!/bin/bash
# Display a simple message with arguments
echo "Hello, $1! This is a simple bash script with $2 arguments being used"

Arguments: Testuser two

Script with shebang header and no arguments

A script with shebang header, but without arguments will be executed with the given shebang interpreter.

Make sure the path to the interpreter in the shebang is correct when executing the script via Run Command. In order to run i.e. a Python script like in the example below, Python needs to be properly installed on the server before you execute the script.

Example script:

#!/bin/python3
# Display a simple message
print("Hello, world! This is a simple python script without arguments being used")

Script without shebang header

A script without shebang will be executed as bash script.

Example script (displays system information):

echo "System Info: $(uname -a)"

Examples

Custom script on a Windows Server VM

In this example we run a simple script to show a message with some arguments on a Windows Server.

Example script:

param (
  [string]$arg1,
  [string]$arg2
)

Write-Host "Hello, $arg1! This is a simple Powershell script with $arg2 arguments being used"

Arguments: Testuser two

The Output contains the desired result value with the arguments included:

Custom script on a Linux VM

In this example we run a simple “Hello World” script on a Linux Server:

Also here the Output contains the desired result value “Hello World!”:
