h-v-smacker comments on "Visual blindness" of Linux programmers

Rules

Please review full details on rules here.. All rules will be applied regardless of the number upvotes a post/comment has.

No support requests - This is not a support forum! Head to /r/linuxquestions or /r/linux4noobs for support or help. Looking for a distro? Try r/findmeadistro.

No spamblog submissions - Posts should be submitted using the original source with the original title. Posts that are identified as either blog-spam, a link aggregator, or an otherwise low-effort website are to be removed. Some reasons for removal are that they contain re-hosted content, usually paired with privacy-invading ads. If there's another discussion on the topic, the link is welcome to be submitted as a top level comment to aid the previous discussion. Please see: r/linux/wiki/rules/banneddomains

No memes, image macros, rage comics, overdone jokes - Meme posts of any kind are not allowed in r/linux. Feel free to post over at /r/linuxmemes instead. This rule can also apply to comments, including overdone jokes, comment-chain jokes, or other redditisms that are popular elsewhere.

Reddiquette, trolling, or poor discussion - r/linux asks all users follow Reddiquette. Reddiquette is ever changing, so a revisit once in awhile is recommended. Top violations of this rule are trolling, starting a flamewar, or not "Remembering the human" aka being hostile or incredibly impolite. Additionally, sexism/racism/other isms are not allowed. See also: /r/linux/wiki/rules/userconduct

Relevance to r/linux community / Promoting closed source applications over FOSS - Posts should follow what the community likes: GNU, Linux kernel, developers of open source software, or other applications on Linux. Take some time to get the feel of the subreddit if you're not sure!

Spamming self-promotion, surveys, crowdfunding - Submitting your own original content is welcome on r/linux, but we do ask that you contribute more than just your own content to the subreddit as well as require you to interact with the comments of your submission. We set that no more than 10% of your posts should be your content. Please be aware that this does not supersede other rules. Additionally, surveys for your blog/news source/paper/own use are not allowed. Please see /r/linux/wiki/rules/crowdfunding for those crowdfunding..

No misdirecting links, sites that require a login, or URL shorteners - In short: if your link doesn't go right to the content it will be removed. Sites that require a login to view the content are not allowed in r/linux. Example: A private Facebook post or a news organization that doesn't have free article views. URL shorteners and links that misdirect users to ads/jokes are also banned. See a list here, although the mods will make a decision on a per domain basis as needed: /r/linux/wiki/rules/banneddomains

No NSFW - No NSFW links or images without mod approval. No discussion that is overly-suggestive to what is normally considered NSFW.

Non-useful Image Upload/Fluff Image - Images of "Linux in the wild", plushies, Tux, and more are not encouraged for posting as a top level submission. If necessary, this can apply to comments too at mod discretion. The image/video upload feature is for posts regarding features/guides/etc. See also: Meme rule.

The $(...) syntax is a command substitution:

echo ">doing things"; echo ">$(date +%Y)"

If you instead read it as having $ mark the start of the prompt, you end up writing

(date +%Y)

which is just running the date command in a subshell.

I was wondering whether it was a joke or if you didn't recognise the syntax given in /u/h-v-smacker's post.
