Inside Distrobox or not?

[doganulus]

I like to have an alias declaration that works differently depending on my environment:

# Host
alias code=flatpak run com.visualstudio.code

# Distrobox
alias code=distrobox-host-exec flatpak run com.visualstudio.code

Is there a stable environment variable you can suggest to distinguish whether I am in a distrobox?

Normally I am looking for something like DBX_VERSION or equivalent. But open to other suggestions.

Ok, I think an existence check for /usr/bin/distrobox-host-exec would work.

My script at ~/bin/code is like that:

#!/bin/sh
if [ -x "/usr/bin/code" ]; then
    /usr/bin/code "$@"
elif [ -x "/usr/bin/flatpak" ] ; then
    /usr/bin/flatpak run com.visualstudio.code "$@"
elif [ -x "/usr/bin/distrobox-host-exec" ] ; then
    /usr/bin/distrobox-host-exec flatpak run com.visualstudio.code "$@"
else
    echo "Cannot run code"
    exit 255
fi

You should have an env var called DISTROBOX_ENTER_PATH when you are in the distrobox. could be cleaner than checking for a bin.
