&gt; I quickly jump to python instead of using Bash even for the simplest of scriptsYou don&#x27;t seem to respect the old, venerable, well-tested adage: &quot;once your shell script becomes too complex, switch to a real programming language like python&quot;.Or, the zen version (formally equivalent, but with quite a different tone): &quot;once your program becomes sufficiently simple, turn it into a beautiful shell script&quot;.

Oh yeah! I was unaware too! Nowadays I quickly jump to python instead of using Bash even for the simplest of scripts , but this could help creating tiny and easy to understand scripts for some integrations...

Yes, but also:<a href="https:&#x2F;&#x2F;wiki.ubuntu.com&#x2F;DashAsBinSh#Why_was_this_change_made.3F" rel="nofollow">https:&#x2F;&#x2F;wiki.ubuntu.com&#x2F;DashAsBinSh#Why_was_this_change_made...</a>&gt; [bash] is rather large and slow to start up and operate by comparison with dashFor more complex regular expressions, you can use `sed`.--It&#x27;s all a matter of context. Sometimes simple ## and %% param substitutions are the best tool for the job.I think bash is a fantastic interactive shell and a lousy script runner.

It&#x27;s time for me to re-read the man page for bash. I was not aware of BASH_REMATCH, wow. It&#x27;s in the first snippet on the linked page, and would save the hassle of using multiple var expansions of the %% and ## et al sort.

MQTT is a fantastic protocol.I basically do the same as the author but use nutshell and its powerful pattern matching [0] as the router-[0] <a href="https:&#x2F;&#x2F;www.nushell.sh&#x2F;cookbook&#x2F;pattern_matching.html#pattern-matching-on-types" rel="nofollow">https:&#x2F;&#x2F;www.nushell.sh&#x2F;cookbook&#x2F;pattern_matching.html#patter...</a>

Interesting... I didn&#x27;t know about this, although I was pretty satisfied with the simplicity of MqttDroid (after I fixed a bug: <a href="https:&#x2F;&#x2F;github.com&#x2F;LightJockey&#x2F;MqttDroid&#x2F;pull&#x2F;3">https:&#x2F;&#x2F;github.com&#x2F;LightJockey&#x2F;MqttDroid&#x2F;pull&#x2F;3</a>). Will investigate to compare.

For those using termux, termux widgets are exposed to Android device control so you don&#x27;t need the MqttDroid app
