Re run the script from the point of failure
Hello

I have a shell script with multiple sections in it. Like, verify pre-requisites, ch co version, stop services , install product , post migration steps, start services, send status email.

If the script fails at certain step, (like after product installation) it can't be re-run since the install should not be run before cleanup. I have logicin the script to halt the script if this product is already installed ,but I would like is to track successful completion of each step, and if it fails at any point, re-running the script should pick it up from failed step.

For example, I have 10 sections in the script. For some reason, script failed at 6th step. After I correct the issue that caused the failure, re-running the script should run from step 6 and not from step 1.

I have seen someone do this by writing the successful completion to a text file and then checking that text file when re-running it , but not sure how this can be done.

Thoughts and help please

This has been asked before. See if there is anything in this thread that helps: Resume from last failed command
