This was very stimulating and thoroughly enjoyable. It allowed me to understand how many of the subtleties I observed and experienced over the years come together.

I've been programing with Bash for two weeks, and even I can see just how powerful these tips are. I guess that the presentation was for advanced users, so I admit that the pace is far too fast for me right now, but that's the beauty of video. I can pause and take the information in, or code with the example onscreen, then unpause. Thank you for the knowledge!

The best part of this whole video is right near the end showing the declaration of functions and parameters that can run on remote hosts. I knew about declaring functions in the current shell but this makes me want to convert some of my scripts to functions now just so I can run them on other hosts without having multiple copies of scripts all over the place. Awesome even eight years later.

He's probably referring to the extended globbing (extglob) patterns, and/or the ;& and &;; operators that allow multiple patterns to match the same input string.

Well, maybe that is due to the 6 years that went inbetween, but these days theres quite a few situations where you won't have bash, I. E. when using a Docker container or an IOT device with a slim Linux. And even if you're on a full blown system better don't forget the shebang for bash if you use bashisms, as lots of people use I. E. zsh, including most people that use Mac OS as it's their default shell

I'm sorry, but I kept waiting for the promised "advanced" usages, yet all I got were the same old bog-standard features I've known about for ages. Loops, tests, functions, parameter expansions? What's advanced about those? Only the very last hint with *declare* was kind of new to me. I had never thought about using it in that way before. I suppose it will help some relative newcomers, and more power to them, I guess, but the title is a bit misleading. You'll learn much more reading the Bash FAQ and Bash Pitfalls pages at Greg's Wiki.

@@jamespannacciulli3029 James, I highly enjoyed your talk (I even learned a few neat tricks I haven't thought of). But please replace all those "echo" and "echo -e" with "printf" equivalents ^^ (let echo die... users should use printf. It will be much more consistent in its display, across shells and versions, and will be without several edge cases (printf "%s " "-anything starting with a minus", for exemple, will never barf. and lots of other related problems get avoided as well)

question: the loop examples: is he loading them out of a file, or where does it come from? thanks in advance
@jamespannacciulli30295 жыл бұрын
eventually, i released the scripts i made to pre-load my example commands as ariketa: git.jpnc.info/ariketa/about/ basically, i put all the examples ahead of time into an array in memory, using bind shortcuts to be able to quickly cycle through them as if they had been typed into the shell directly. i figure this saves time so that i can keep the pace up, while avoiding all the obligatory live demo typos. so something like "while read var1 var2; do echo $var2 $var1; done" would be loaded onto the command line when i cycled forward to that example from my array, then i would just type in the text like "one two" manually and the loop would return "two one" in that case. in case you are interested, i made a little write-up of my thinking and methodology here: www.jpnc.info/posts/en/2017/06/ariketa.yo/ hope that answers your question, sorry for the late response!

It's so sad to see GNU/Linux infection splitting through community. Hearing it being pronounced GNU/Linux feels so cringeworthy. What exactly do these people see is the benefit that they are bringing to the table to the world? I can't think of anything other than some salute a recognition towards GNU and FSF? I do respect them, but I do not respect their attempt to change what most world knows as Linux to some cumbersome GNU/Linux.
@jamespannacciulli30298 жыл бұрын
+EmperorTerran Tell us how you really feel. But seriously, why so sad about my having used the more complete, more accurate name for the OS? Although I do tend to casually refer to the OS as "Linux", I understand that this is taking a shortcut at the expense of somewhat misrepresenting the OS. It is actually ironic that I take this shortcut, as I am primarily interested in running a GNU OS, whether it were GNU/Linux, GNU/Herd, or GNU with some other free software licensed kernel. On the other side of that coin, I expect we should continue to see more OS's made combining the Linux kernel with non-GNU core libraries and programs, in which case the distinction between GNU/Linux and Linux without GNU, such as Android, becomes much more important. If I am giving a talk, I'll at least refer to the OS officially by what I consider to be its proper name, even if I may use the name "Linux" colloquially. Of course, I recognize that referring to it in this specific manner is also an implicit advertisement for the GNU project, and I definitely approve that message.
