findExecutable file path-list

findExecutable searches for an executable named file in directories identified by path-list. The result will be the executable file concatenated with the matching path. If an executable file cannot be found in path-list, findExecutable returns an empty string.

findExecutable is provided as an alternative to lookPath so that you can interrogate the system PATH as it would be configured after chezmoi apply. Like lookPath, findExecutable is not hermetic: its return value depends on the state of the filesystem at the moment the template is executed. Exercise caution when using it in your templates.

The return value of the first successful call to findExecutable is cached, and future calls to findExecutable with the same parameters will return this path.


On Windows, the resulting path will contain the first found executable extension as identified by the environment variable %PathExt%.


{{ if findExecutable "rtx" (list "bin" "go/bin" ".cargo/bin" ".local/bin") }}
# $HOME/.cargo/bin/rtx exists and will probably be in $PATH after apply
