I know lists like this will almost always contain at least one command that I, or any other sys admin on here, would use fairly regularly. But it would be nice if just once an article about "obscure" CLI commands didn't include stuff that's the most basic of essential every day staples for any *nix administrator.

Including stuff like vi and emacs is just ridiculous, quite frankly. If you haven't heard of them already then you really have no place in the command line, let alone reading a document like this.

Most of these types of articles should be rebanded as "beginners cheat sheet for handy command line tools" or just not written to begin with (because, frankly, they're just repeating all the same recommendations as every other article like this that pops up each week and few of them have any descriptions that are accurate either).

Maybe my job this weekend will be to write my own version of these documents but with a decent selection of programs, descriptions and example usages?

Maybe your job this weekend should be to get a little exercise before writing on the internet?

It's a nice little summary of cool tools. "Some are little-known, some are just too useful to miss, some are pure obscure".

I'm a big fan of Joey Hess' moreutils - https://joeyh.name/code/moreutils/

Examples:

- sponge: read in all of stdin, then write to the given file. Great for pipelines: sed "s/root/toor/" /etc/passwd | grep -v joey | sponge /etc/passwd

- vipe: easily drop a $EDITOR instance in the middle of a pipe chain

- ts: timestamp all standard input; great for long-running output

How is sponge different from > filename?

The best not-so-well-known tool he mentiions is socat. If you use netcat, socat is like netcat on steroids. It's just a bit hard to remember all the options, but next time there's something crazy you want to do with netcat that it doesn't support, like tunnelling raw packets from a wireless interface on a machine in firewalled corporate network through an SSL tunnel to home machine and dumping those packets locally to a serial port, socat can pretty much do it all.

I hear nmap's ncat is great as well but I haven't tried it yet. I agree that socat is invaluable, especially when dealing with serial devices.

I don't really think it's fair to call anything that's in a POSIX standard obscure (like xargs).

Most of these are fairly common, and many of the descriptions are terrible, for example: `rsync` doesn't "[Keep] filesystems in sync over SSH"; it's a versatile `cp`-like for dealing with remote systems efficiently that happens to support transfers over SSH.

As I can no long edit my comment: when I made the parent comment, the title referred to them as _Obscure_ tools.

For being "obscure", htop manages to find its way into a very large proportion of *NIX screenshots on the web.

Not to mention vim, rsync, curl, and ack, all of which I (and I had assumed everyone else) use on a regular basis.

[+] eropple|12 years ago|reply
I still don't use ack, mostly because it's not installed everywhere I go on a regular basis and so my fingers still go 'grep' when I think 'text search'.

(I also rarely use curl, because my fingers are trained for wget -qO. That one is a personal quirk, though, I didn't know about curl until I'd had that one imprinted on my brain. The cool thing there, though, is that wget -qSO will send headers to stderr and content to stdout, so you can get fancy.)

[+] defrex|12 years ago|reply
I'd highly recommend checking out httpie as a replacement for curl. I find the interface much more intuitive.

I'd love to see a site just like this, but cataloging all the best Unix console tools.

It sounds ridiculous, but you can tell a lot about a console program from a screenshot.

I would like to see a graphical terminal emulator. When I mean by this is that the terminal emulator works the same as usual- it should display normal output, support ANSI escape sequences and have scroll-back. But it also should be able to display graphics. If your UNIX command line program happens to output a graph, it shows up on the terminal. The graph is embedded inline with the text and you can scroll back to it.

Interactive programs should also possible- think of a schematic editor or a figure editor running right on your terminal emulator.

The point of all this is to retain the context of whatever you're doing without having to switch windows. That and to advance the state of the art of console tools- certainly they have not changed in decades.

On the topic of ways to improve the terminal, I'd like to see output separated from input.

Put the prompt 1/4 of the way down the screen instead of at the bottom. Above the prompt, we have a backlog of the commands we input. As we press up, it scrolls through the backlog, as normal.

Below the prompt, we see the output of the command.

I'd also like to see tab completion (and maybe some form of hinting) on programs, not just file paths.

[+] rakoo|12 years ago|reply
Check out terminology [0]. The video is quite long but impressive.

There was a work by someone on github for building a new kind of terminal. It wasn't line-based, rather "context-based": the output of the command was written next to the input, but you could write commands in the same terminal next to each other. It was some amazing stuff, but I can't find it (I think the logo was an octopus or something like that, and the "backend" was emacs)

Incorrect title for the post. Many of the tools mentioned are very commonly used. Also, except nice screenshots, this article is just a listing of tools with very little useful info to go with them.
[+] oinksoft|12 years ago|reply
The author mentions App::Ack, but I doubt you'll go back to using `ack` once you've tried The Silver Searcher (`ag`).

Good list thank you. Another good one is "VnStat/VnStati" I use it generate traffic graphs.

Does anybody know if a HTML5 version of Nethack exists?

My latest discovery: jq - command line json processing, formatting and colouring.
[+] owenversteeg|12 years ago|reply
I was going to mention jq. It's great, and replaces the previous json tool I was using (can't remember the name now, but it wasn't as useful.) I hope it becomes more popular.
