I agree, but if a script is going to use the CLI then it's the script's responsibility to parse the prompts and not to blindly send strings to the program. `expect` exists since 1990, use it or reinvent it.
- woah 10y agoCan you go over some good ways to use expect to avoid this type of issue?
- tangus 10y agoYou simply use it to wait for the appropriate prompt before sending anything. If the expected prompt never arrives, something is wrong (CLI changed), so abort. The snippet for this particular case could be something like set timeout=1 expect { "enter \"p\" for pre-configured paranoia mode" { puts p\n } timeout abort eof abort }
