How can I fix the "watch error opening terminal unknown" when running `watch` in a script or cron job?

To fix this in scripts or cron jobs, you generally need to make `watch` less reliant on terminal features. The simplest solution is to use `watch -n 1 'your_command | cat'` to pipe the output, effectively disabling the clear screen functionality. Alternatively, you can explicitly set `TERM=dumb` before running `watch`, like `TERM=dumb watch -n 1 'your_command'`, which tells `watch` to use minimal terminal capabilities.
