Condition for Create a Jenkins Job that Runs an External Shell Script File on the Server

Description:
Sometimes, you want Jenkins to execute pre-written shell scripts instead of typing commands directly in the job. This approach is useful for automating complex tasks, running scripts shared across multiple jobs, or keeping code organized. This task helps you to create a shell script on the Ubuntu server and configure a Jenkins Freestyle job to run it.

Steps

Step 1 — Create the Shell Script File on Ubuntu
Open the terminal.
Find your username:
```
whoami
```
Create the script using nano (replace youruser with your username):
```
nano /home/soft13/test.sh
```
Paste the following content into the file:
```
#!/bin/bash
echo "Script executed!"
```
Save and exit: CTRL + O → Enter → CTRL + X
Step 2 — Make the Script Executable
Run:
```
chmod +x /home/soft13/test.sh
```
Verify permissions:
```
ls -l /home/soft13/test.sh
```
You should see: -rwxr-xr-x test.sh
Step 3 — Give Jenkins Permission to Run the Script
Jenkins runs as user jenkins, so assign ownership and permissions:
```
sudo chown jenkins:jenkins /home/soft13/test.sh
sudo chmod 755 /home/soft13/test.sh
```
Alternatively, move the script to a Jenkins-friendly folder:
```
sudo mv /home/soft13/test.sh /var/lib/jenkins/
sudo chmod +x /var/lib/jenkins/test.sh
```
Step 4 — Create a Jenkins Job
Open Jenkins Dashboard → Click New Item
Enter Job Name: run-sh-script
Select Freestyle Project → Click OK
Step 5 — Add a Build Step
Go to Build → Add build step → Execute shell
Enter the script path:
```
/var/lib/jenkins/test.sh
```
Step 6 — Save & Run Job
Click Save → Click Build Now
Step 7 — Check the Output
Under Build History, click Build #1 → Console Output
You should see:
```
Script executed!
Finished: SUCCESS
```
Goal
Jenkins successfully executes an external shell script, allowing you to automate tasks stored in script files.
