Hi all,

can I run a command inside a playbook when finished the tasks?

.

you can use command module or shell module to execute any linux command inside a playbook.
for more details you can go through these links: http://docs.ansible.com/ansible/latest/command_module.html
http://docs.ansible.com/ansible/latest/shell_module.html

There are so-called < post tasks >. Search the documentation.

Hi all,

I get the following error

fatal: [SW2]: FAILED! => {“changed”: true, “failed”: true, “rc”: 2, “stderr”: “diff: SW1_show_run.txt: No such file or directory\ndiff: SW2_show_run.txt: No such file or directory\n”, “stdout”: “”, “stdout_lines”: }

This is my script
diff SW1_show_run.txt SW2_show_run.txt >> diff.txt

And this is how I add it to my plabook

  • script: /Network_Automation_Ansible/backups/show_run/comp.sh

Thanks all

Both files SW1_show_run.txt and SW2_show_run.txt exist at the destination?

Also try giving full path to the files.

Hello Fayad,

Yes they exist in the folder if I execute the script directly in the folder (sh diff.sh or bash diff.sh) it works.

thanks.

fatal: [SW1]: FAILED! => {“changed”: true, “failed”: true, “rc”: 1, “stderr”: “”, “stdout”: “”, “stdout_lines”: }

Thanks
