#csh — Public Fediverse posts

Yes, you use this command sequence from any of your most favorite shells, to compile your Source Code

Regardless of the operating system you run, you can get a command shell which is Open Source by downloading a GNU package sequence for it.

For mac & win64 they are also available.

Without a command line  programming would be impossible

Browsing through the Linux kernel

• section devices
• sub section block
• file badblocks.c
• level critical

When I look in sources for real work I use the old school method

• terminal (ba(c)(k)(z)(fi)sh)
• vim
• logic
• patience

This is just a lazy exercise

DESCRIPTION

badblocks is used to search for bad blocks on a device (usually a disk partition). device is the special file corresponding to the device (e.g /dev/hdc1). last_block is the last block to be checked; if it is not specified, the last block on the device is used as a default. first_block is an optional parameter specifying the starting block number for the test, which allows the testing to start in the middle of the disk. If it is not specified the first block on the disk is used as a default.

lolcat tricks and fun

In case you have ever wondered what it would look like to have all of your favourite console output piped through lolcat(6) 🏳️‍🌈, here is a nice example

required (one of *sh is enough)

• Open Source OS
• sh
• csh
• ksh
• zsh
• bash
• fish
• syntax skills on piping I/O
• love of colours
• typing skills
• sense of humour

typing
man lolcat

...will get you the standard sh output delimited by the man command itself. This means that I used a simple trick to get all of my output piped through lolcat

ssh -Xv -p65534 -l userid |lolcat

This command syntax gets all of my commands in that ssh session piped through lolcat, creating an awsome rainbow colour galore

notes

• ssh secure session piped through lolcat gets you a slower output, compliments of the inner workings of lolcat. Feel free to optimize the program and release the patches if the lowerspeed irks you.
• test the speed by doing
• ls -lR ~ and compare that in a standard ssh sessios without full lolcat pipe
• I used the -X switch because I also start X programs from this shell (which I run in Xorg {it also works in wayland})
• I use the -v switch because I love log messages of ssh
• you can also animate your piped lolcat output with
• lolcat -a
• I watch the output on a large TV also, because lolcat(6) 🏳️‍🌈 is that awsome

Termux

If you want a nice to great full linux stack for your android, seek for Termux.

do not install the playstore version!

Alphabet {google} sabotages OpenSource projects on Android. Get termux straight from the home page

Termux is a full linux ENV:

termux installs minimal

• download
• shell spawns with instructions
• you have to follow them!!!
• once familiarized (easy when you know Debian)
• start your commands, install them individually if their'e not in the default install
• enjoy a free Linux ENV: in the hostile (google) Android ENV
• keyboard assistance is at the bottom of the bash window
• CTRL
• ALT
• cursors
• PaGeUP
• PaGeDOWN
• Home
• End
• Esc
• /
• -
• tab
• are all keys to assist you in fluent linux sh typing
• you may install any sh supported in linux bash csh ksh zsh fish

caveats

• There are a few, however you will still be able to work there
• check your internal ssd space, termux works there by default
• filesizes can be surprising
• I just install Midnight Commander on one of my Androids and the supporting libs (including clang took a massive 540MiB while mc itself is small)
• I only noticed because on a default debian install those libs are already there for other elf binaries
• on the Slitaz distro those libs are also installed, when mc is invoked / installed

Termux is Linux joy on Android

I still want to get rid of Photoshop and move to @Krita .

One thing I was missing were the vector shapes. So here is a Python program that converts Photoshop csh and psp files to Krita svg shapes.

It comes as a plugin and as a standalone Python file with a TKInter UI. Tested on Windows and MacOS.

Here's the plugin: codeberg.org/xanathon/csh2krita

Extensive readme in the repository.

Regretfully I have to inform you that your detector is flawed. Any errors and mistakes you've found are all from my brains.

curl

Daniël Stenberg

facts and praise

I'm fortunate that I am allowed to follow Daniël, lead programmer of the mightycurl. The reason I formulated the line in this way, is because only through the power of the FediVerse I've gotten a boost from someone I follow, who found a post of the lead programmer or curl interesting

stats:

install base => 20000*106 devices

20 billion+ installations!

curl is used in command lines or scripts to transfer data. curl is also libcurl, used in:

• cars
• television sets
• routers
• printers
• audio equipment
• mobile phones
• tablets
• medical devices
• settop boxes
• computer games
• media players

Curl is THE Internet transfer engine for countless software applications in over twenty billion installations!

curl is used daily by virtually every Internet-using human on the globe!

curl is 30 years old

Let that sink in!

Opinion

curl is mature critical network infrastructure software that we all need to have our internet powered software / hardware to function in respect to data transfer.

The syntax to use curl in simple implementations is IMHO quite easy. In case you need to know an extra option, the executable and libcurl have excellent documentation. End users normally interact with curl using the (elf) binary on Linux based POSIX operating systems. The more mature BSDs have another binary format

Just type curl to get an initial output which looks like this on my current system

curl
curl: try 'curl --help' or 'curl --manual' for more information

then type

curl --help
Usage: curl [options...] <url>
 -d, --data <data>           HTTP POST data
 -f, --fail                  Fail fast with no output on HTTP errors
 -h, --help <subject>        Get help for commands
 -o, --output <file>         Write to file instead of stdout
 -O, --remote-name           Write output to file named as remote file
 -i, --show-headers          Show response headers in output
 -s, --silent                Silent mode
 -T, --upload-file <file>    Transfer local FILE to destination
 -u, --user <user:password>  Server user and password
 -A, --user-agent <name>     Send User-Agent <name> to server
 -v, --verbose               Make the operation more talkative
 -V, --version               Show version number and quit

This is not the full help; this menu is split into categories.
Use "--help category" to get an overview of all categories, which are:
auth, connection, curl, deprecated, dns, file, ftp, global, http, imap, ldap, output, pop3, post, proxy, 
scp, sftp, smtp, ssh, telnet, tftp, timeout, tls, upload, verbose.
Use "--help all" to list all options
Use "--help [option]" to view documentation for a given option

When you type curl --manual|less you get the manpages which I delimited with less through a vertical pipe

NAME

    curl - transfer a URL

SYNOPSIS

    curl [options / URLs]

DESCRIPTION

    curl is a tool  for transferring data  from or to a  server using URLs.  It
    supports these protocols:  DICT, FILE,  FTP, FTPS,  GOPHER, GOPHERS,  HTTP,
    HTTPS, IMAP,  IMAPS, LDAP,  LDAPS, MQTT,  POP3, POP3S,  RTMP, RTMPS,  RTSP,
    SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS.

    curl  is  powered  by  libcurl  for  all  transfer-related  features.   See
    libcurl(3) for details.

URL

    The URL syntax is  protocol-dependent. You find  a detailed description  in
    RFC 3986.

I can also type man curl to get a nice output:

curl(1)                                         curl Manual                                        curl(1)

NAME
       curl - transfer a URL

SYNOPSIS
       curl [options / URLs]

DESCRIPTION
       curl  is  a tool for transferring data from or to a server using URLs. It supports these protocols:
       DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT,  POP3,  POP3S,
       RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS.

       curl is powered by libcurl for all transfer-related features. See libcurl(3) for details.

URL
       The URL syntax is protocol-dependent. You find a detailed description in RFC 3986.

       If  you provide a URL without a leading protocol:// scheme, curl guesses what protocol you want. It
       then defaults to HTTP but assumes others based on often-used hostname prefixes.  For  example,  for
       hostnames starting with "ftp."  curl assumes you want FTP.

       You  can specify any amount of URLs on the command line. They are fetched in a sequential manner in
       the specified order unless you use -Z, --parallel. You can specify command line  options  and  URLs
 Manual page curl(1) line 1 (press h for help or q to quit)

The reasoning behind curl --manual is simple. On a machine without the manual system you still need access to the full manual. This is one of the reasons why man curl is also implemented as curl --manual

An important RFC is echoed to my terminal in the man curl output which is RFC 3986

A Uniform Resource Identifier (URI) is a compact sequence of
characters that identifies an abstract or physical resource. This
specification defines the generic URI syntax and a process for
resolving URI references that might be in relative form, along with
guidelines and security considerations for the use of URIs on the
Internet. The URI syntax defines a grammar that is a superset of all
valid URIs, allowing an implementation to parse the common components
of a URI reference without knowing the scheme-specific requirements
of every possible identifier. This specification does not define a
generative grammar for URIs; that task is performed by the individual
specifications of each URI scheme.

I shall not quote the whole RFC 3986 here. You can read all about it on the RFC site (see sources)

As you can see curl is thorougly documented, has all the features a simple end user needs to fetch all kind of data, scaled up all the way to the extensive complex features router hardware et all, needs to transfer data.

programming route

I came to this toot when I saw that certain external feature code, which lives in stable external libraries, is now being removed from curl. I should say the code is depreciated then phased out.

This is a logical step

• It takes resources to maintain external code
• If the (shared) libraries are stable and mature, it's much better to just call those libraries and be done.
• The more external code you can remove from your project the better it is for all the programmers

The same is also happening in the Linux kernel, they are following in the footsteps of curl

Conclusion

There is a treasure trove of information in the sources. Just reading the pages on RFC 3986 will keep you occupied for hours.
Have fun and keep reading / learning and programming!

TIL today I RTFM!

command

ntfy

Today I read the brief synopsis of ntfy Android. I saw there that via linux the control and operation is fairly simple & straightforward

I went to the site and started reading.

ntfy via linux is easy to use

• simple HTTP PUT/POST commands are used

sh

curl -d "Backup successful 😀" ntfy.sh/mytopic

a.out

ntfy publish mytopic

"Backup successful 😀"

HTML

POST /mytopic HTTP/1.1
Host: ntfy.sh

Backup successful 😀

javascript

fetch('https://ntfy.sh/mytopic', {
    method: 'POST', // PUT works too
    body: 'Backup successful 😀'
})

golang

http.Post("https://ntfy.sh/mytopic", "text/plain",
   strings.NewReader("Backup successful 😀"))

python

requests.post("https://ntfy.sh/mytopic",
    data="Backup successful 😀".encode(encoding='utf-8'))

php

file_get_contents('https://ntfy.sh/mytopic', false, stream_context_create([
    'http' => [
        'method' => 'POST', // PUT also works
        'header' => 'Content-Type: text/plain',
        'content' => 'Backup successful 😀'
    ]
]));

Markdown formatting¶

Supported on Android & webApp

You can format messages using Markdown 🤩. That means you can use bold text, italicized text, links, images, and more. Supported Markdown features (web app only for now):

Emphasis such as bold (bold), italics (italics)
Links (some tool)
Images ()
Code blocks (code blocks) and inline code (inline code)
