Tim ChaseTIL that modifying NF in <a href="https://mastodon.bsd.cafe/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> has an instant effect, so if you do$ echo a b c | awk '{while (NF){print $(NF--)}}'the post-decrementing removes the entry before the variable gets accessed, resulting in it printing blanks, so instead you have to access the variable before doing the post-decrement:$ echo a b c | awk '{while (NF){print $NF; NF--}}'to print each item in reverse.Which seems weird given what I understand about how post-decrement is *supposed* to work.(HT: <a href="https://oldbytes.space/@drscriptt" class="u-url mention" rel="nofollow noopener" target="_blank">@drscriptt</a> whose <a href="https://mastodon.bsd.cafe/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> sent me down this rabbit-hole of learning)

DrScriptt<a href="https://mastodon.bsd.cafe/@gumnos" class="u-url mention" rel="nofollow noopener" target="_blank">@gumnos</a> That didn't quite work, but I did get it to work.Here's what I have:awk -F. '{for (C=NF;C; C--){printf "%s.", $C}; printf "oid."}'NF-1 was missing a component.I also added curly braces around the 1st printf to make it more obvious what the for loop applied to.I wasn't aware that the for loop only applied to the very next instruction. <a href="https://oldbytes.space/tags/TIL" class="mention hashtag" rel="nofollow noopener" target="_blank">#TIL</a> <a href="https://oldbytes.space/tags/AWK" class="mention hashtag" rel="nofollow noopener" target="_blank">#AWK</a>

awbWhat's useful about Perl is that it fits the Unix tools approach well. You can write quick one-liners and put them in a pipeline. You then gradually enhance functionality until you arrive at a standalone script. Like Shell. Like AWK. Ruby is kind of like that as well. Python is not.This doesn't mean the opposite works equally well. The bare minimum to turn a language's REPL into an interactive Shell is I/O redirection and pipelines without much extra syntax.<a href="https://mastodon.sdf.org/tags/shell" class="mention hashtag" rel="nofollow noopener" target="_blank">#shell</a> <a href="https://mastodon.sdf.org/tags/perl" class="mention hashtag" rel="nofollow noopener" target="_blank">#perl</a> <a href="https://mastodon.sdf.org/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> <a href="https://mastodon.sdf.org/tags/ruby" class="mention hashtag" rel="nofollow noopener" target="_blank">#ruby</a> <a href="https://mastodon.sdf.org/tags/python" class="mention hashtag" rel="nofollow noopener" target="_blank">#python</a>

NoGoo.meHey beloved <a href="https://gts.nogoo.me/tags/nogoome" class="mention hashtag" rel="nofollow noopener" target="_blank">#noGooMe</a> users, A quick reminder that you *must* have the proxy image option unchecked when using this <a href="https://gts.nogoo.me/tags/searxng" class="mention hashtag" rel="nofollow noopener" target="_blank">#SearxNG</a> instance. It can be disabled, if you previously had it enabled, browsing to /preferences, then selecting the "privacy" tab and uncheck the "image proxy" switch. It is disabled by default so any first connection to this instance has the proper setting set up. If you do have it enabled, you’ll quickly be blocked at the firewall level by our <a href="https://gts.nogoo.me/tags/awk" class="mention hashtag" rel="nofollow noopener" target="_blank">#awk</a> AI agent 🤖 My reason for disabling this feature is that it generates loads of requests from the instance IP to the external engines. And this makes those block us really fast. This means that the engines will have *your IP* logged when you search for images, only. Classical text search are still masqueraded with our instance IP.
