vmtouch VS pup

VMTouch may be helpful. https://hoytech.com/vmtouch/

Just lock the file into memory using:

```vmtouch -l /path/to/binary```

You're claiming that gnome loads all of itself into memory so that it can be faster. Now there are a few reasons why I don't think that's a reasonable idea, but assuming that you wanted that... using techniques like vmtouch to keep the files in the disk cache would make it so that gnome wasn't actually using the full 1GB. The "cached" files could be evicted from the cache if some other program needed that memory. Where as loading all of gnome in at startup regardless of whether it's actually used is probably not a good idea.

It is a mainstream thing. It's enabled by default on every Windows install, as far as I know, although you may not be impressed by its understanding of what your frequently opened programs are. It's been about ten years since I ran Windows, but I used to have a batch script to read everything in a directory so that it would be in the disk cache and subsequent accesses would come from RAM. The Linux equivalent of my script is vmtouch, although that's a lot more full-featured.

vmtouch.

And lnk=$(curl -s https://www.selfstudys.com$url |grep "PDFFlip" | cut -d '"' -f 6) to lnk=$(curl -s https://www.selfstudys.com$url | pup "div#PDFF attr{source}" ) here pup will print content of source attribute from div tag with id PDFF i dont know that much about html & css so this is what i came up with. but i am sure you can also select class & make list of suburls from them. check out the video from bugswriter on pup or read docs from git hub for more info github link: https://github.com/ericchiang/pup

jq is pretty amazing. If you are comfortable with its jquery-like CSS selector syntax, then I should also mention a couple similar cli utilities that apply it to HTML: htmlp and pup.

Regex is not a great tool for parsing web pages. Open up a browser dev tools window and select a bit of the page. Right click > copy... XPath expression or CSS selector. A proper web scraping tool will accept either of those. No muss, no fuss. You can even use simple command line tools: xpath or pup

This is HTML to JSON, written in Rust, and there's also pup[1] which I found out about just the other day on HN[2] which uses a very similar syntax (CSS selectors) but outputs HTML and is written in Go.

I can see room for both though it would interesting to have a more detailed comparison to go on (e.g. types of HTML, speed etc).

It looks like the project became inactive for a bit and there are alternatives such as htmlq, etc. https://github.com/ericchiang/pup/issues/150

Another tool worth mentioning is pup - it can produce JSON output which means you can pipe it to jq
