Insert Based on Binary

[john-okeefe]

I'm working with my zshenv.tmpl fle and I have a couple lines that I only want to include if nix-env exists. In bash I can use whereis, but how can I check for executables in my tmpl file?

Mostly with lookPath. You can use findExecutable or findOneExecutable to look in values that will be in $PATH.

You can see a fairly extreme example of how I set this up in .chezmoitemplates/programs.tmpl.

As @halostatue says, lookPath is the way. For example, I use:

{{- if lookPath "eza" }}
alias ls=eza
{{- end }}

Thank you both so much. I tried searching for binary, file, and a few others in the docs. But I did not think of searching executable, then even when I did, it pulled up the executable functions, but not lookPath which was all I needed.
