The zb update command clears the locally cached formula definitions, forcing zerobrew to fetch the latest package metadata on the next operation.

​
Usage

zb update

​
Description

This command clears zerobrew’s API cache, which stores formula information. After running zb update, the next time you check for outdated packages or install new software, zerobrew will fetch fresh metadata from the remote repository. Unlike Homebrew’s brew update which updates the tap repository itself, zb update simply clears the cached formula entries to ensure you get the latest information.

​
Examples

Update the formula cache: 
zb update
After updating, check which packages have new versions available: 
zb update
zb outdated

​
Output

When cache entries are cleared: 
==> Cleared 42 cached formula entries.
Run `zb outdated` to check for updates.
When the cache is already empty: 
==> No cached entries to clear.
Run `zb outdated` to check for updates.
