kl.kurwinet.pl is a service which allows you to share output of any terminal program (like cat, echo, make, gcc etc.) using just the most basic unix tools.



$ echo "hello world" | socat - TCP:kl.kurwinet.pl:1337
upload complete, link to file https://kl.kurwinet.pl/o/gin9b
$ curl https://kl.kurwinet.pl/o/gin9b
hello world


Due to the fact that not all implementations of netcat send FIN at the end of transfer, command is a little bit longer as it is required to add ending string so server can know when to finish transfer.

$ echo 'hello world' | { cat -; echo 'kurload'; } | nc kl.kurwinet.pl 1337
upload complete, link to file https://kl.kurwinet.pl/o/x0nhy
$ curl https://kl.kurwinet.pl/o/x0nhy
another hello world


To make your life easier and to live up to the promise this can be used with 3 additional keypresses, you can create shell alias. Remember to replace ~/.bashrc with file that your shell will read. For zsh it will be ~/.zshrc, for dash - ~/.profile.

$ echo 'alias kl="socat - TCP:kl.kurwinet.pl:1337"' >> ~/.bashrc
$ source .bashrc

Now you can upload anything with just 3 more keystrokes adding |kl

$ echo "easy send"|kl
upload complete, link to file https://kl.kurwinet.pl/o/wa84m
$ curl  https://kl.kurwinet.pl/o/wa84m
easy send


For big files it may be advisible to pipe curl output to less

$ cat server.c|kl
upload complete, link to file https://kl.kurwinet.pl/o/80f49
$ curl https://kl.kurwinet.pl/o/80f49 | less

You can also share any binary files - in this example we share an jpg image.

$ cat image.jpg|kl
upload complete, link to file https://kl.kurwinet.pl/o/8lah1
$ curl https://kl.kurwinet.pl/o/8lah1 > image-downloaded.jpg
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

$ nomacs image-downloaded.jpg

Upload error log from gcc and file content in question.

$ gcc main.c 2>&1 | { cat -; printf '\n-----\nmain.c\n-----\n'; cat main.c; }|kl
upload complete, link to file https://kl.kurwinet.pl/o/3wgr6
$ curl https://kl.kurwinet.pl/o/3wgr6


This project is possible thanks to kurload server. With kurload you can self host your own pastebin server with optional ssl if you want to share confidential data.
