How to view the error itself and its context, including 10 lines before and after the error?

To view an error and its context with 10 lines before and after in logs or a code file, you can use the grep command with the -C (context) option in Linux:

grep -C 10 "error" filename.log

This will show 10 lines before and after the found error line.

If you're looking at a stack trace in code, you can use IDE tools or editors that allow quick navigation to the error location and viewing of the context.

For debugging in the terminal, you can use tail to view the last lines of the log and less for convenient viewing with search and scrolling.
