whence

A zsh builtin to indicate how a given command would be interpreted. More information: https://www.unix.com/man-page/OpenSolaris/1/whence/.

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}}"
