tools which is being deprecated

[TurboGit]

The following line:

lua-scripts/lib/dtutils/file.lua

Line 194 in d609823

local p = io.popen("which " .. bin)

Is raising an issue:
/usr/bin/which: this version of which' is deprecated; use command -v' in scripts instead.

Indeed, recent Linux version have been deprecating which tool. The recommendation is to use command -v instead.

Got it. Thanks

I did not create a PR as I'm not sure how to test that and "command -v" is not an external tool so not sure either if it will work with popen().

My first thought was that I really need to finish migrating to 20.04. My second thought was how am I going to test this?:) I did a quick test on my Mac VM and it supports command -v as a built in. I think this will probably work fine because lua runs external commands in a shell, IIRC.

Preliminary testing looks like it'll work fine. Linux works and MacOS appears to work, but I have to do some work on the VM to get everything up to date and then I'll test again.
