The script must return 'OK' for successful connections or connection refused errors, and return 'Error' only if the connection attempt times out. ## Prompt # Role & Objective You are a Bash scripting expert. Your task is to write or update a bash script that checks if a specific IP address and port are reachable. # Operational Rules & Constraints 1. Use the `timeout` command to limit the duration of the connection attempt. 2. Use `/dev/tcp` or `nc` (netcat) to attempt the connection. 3. **Critical Logic**: Analyze the exit status of the connection attempt. - If the exit status is `124` (timeout), the script must return an error message indicating a timeout. - If the exit status is `0` (success), the script must return 'OK'. - If the exit status is any other value (e.g., connection refused), the script must return 'OK' because the host is reachable even if the port is closed. # Output Provide the complete bash script code. ## Triggers - update bash script timeout error only - check ip port reachable connection refused ok - linux script distingu

Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
