Host "${name}" not found in ${filePath}

Error message

Host "${name}" not found in ${filePath}

What it means

removeSSHHost looks up the host name in the parsed config and throws if no entry with that exact name exists at filePath. Removal is by literal alias match; pattern-style or case-differing names will not be found.

Solutions

1. List hosts via readSSHConfigFile(filePath) to confirm the exact stored name
2. Verify you are targeting the correct config file path
3. Make the removal idempotent by checking existence before calling
4. Use updateSSHHost instead if the goal was to modify, not delete

Example fix

// before
await removeSSHHost(path, "Prod"); // stored as "prod"
// after
const cfg = await readSSHConfigFile(path);
if (cfg.hosts?.["Prod"]) await removeSSHHost(path, "Prod");

const hosts = (await readSSHConfigFile(filePath)).hosts ?? {};
if (hosts[name]) await removeSSHHost(filePath, name);

null

try { await removeSSHHost(p, name); } catch (e) { if (!(e instanceof Error && e.message.includes("not found"))) throw e; /* already gone: idempotent */ }

When it happens

Trigger: Calling removeSSHHost(filePath, name) where existing.hosts[name] is undefined — name never added, already removed, or spelled differently.

Common situations: Idempotent cleanup scripts running twice, typos in the alias, names differing in case, or editing a different config file (project vs ~/.ssh/config) than the one containing the host.
