Allow specifying multiple operating systems

[jedahan]

So sometimes I'm using tealdeer on my laptop which is macOS, and looking up a utility that is for linux on another box. I have to -o linux after seeing that the command is not found.

My workaround is function tld { tldr $* || tldr -o linux $* }

I was wondering how you'd feel making this the default behavior.

Hm, what should happen if a command exists both on Linux and on SunOS (with different TLDR-pages), and you call tldr from macOS? 🙂

Perfect is the enemy of good?

I don't like to make things more complicated, but if you are concerned about confusion with automatic fallback, maybe one of all of:

• configurable fallback order as cli arguments with a default
• an indicator of the current fallback at the top or bottom of the rendering
• maybe making this an upstream thing tldr-pages/tldr with symlinks as fallbacks?

Maybe we could allow specifying multiple operating systems for the -o option? tldr -o osx,linux

[BrainMaestro]

Maybe it could fail, but let the user know that the page exists on another os?

[dbrgn]

I'd definitely favor an option where you could specify multiple operating systems in order of precedence (tldr -o osx,linux). Now that we have configfile support, the default setting could even be configurable. Alternatively, you could alias tldr to tldr -o osx,linux.
