try_catch is a proof-of-concept script for applying an error-catching procedure that summarizes and consolidates error message. The main idea is to catch the errors and display it into a more readable format. It also generates a log entry for each run.
try_catch.sh
Contains code for applying an error catching procedure to enable "fancy" logging.
sample-error_collectio.logandsample-error.logcontains sample error output/logs.
Files
- error.log
- Contains the logs for the recently executed script -- only if there were errors.
- Old log is replaced after each execution.
- If there were errors, the error.log is deleted / would not be created.
- error_collection.log
- Contains a collection of logs from different executions / runs.
- Contents of error.log is appended at the bottom of this file after each executions / run.
Both files are auto-generated at the end of the script execution -- if there were errors.
-
Contains a summary of errors (like a table of contents)
- Contains a unique identifier (timestamp + uniqueID)
- Custom error label (optional)
