# whence
> A zsh builtin to indicate how a given command would be interpreted.
- Interpret {{command}}, with expansion if defined as an `alias` (similar to the `command -v` builtin):
`whence {{command}}`
- Display type of {{command}}, with location if defined as a function, or binary (equivalent to the `type` and `command -V` builtins):
`whence -v {{command}}`
- Same as above, except display content of shell functions instead of location (equivalent to `which` builtin):
`whence -c {{command}}`
- Same as above, but show all occurrences on command path (equivalent to the `where` builtin):
`whence -ca {{command}}`
- Search only the `PATH` for {{command}}, ignoring builtins, aliases or shell functions (equivalent to the `where` command):
`whence -p {{command}}`
