[user] sek is a small UNIX-like shell environment.

What you type is run as a command.

[user] alice@sek:~$

[user] sh: less: not found

cat HELLO_WORLD

[user] Welcome to sek!

sek is a virtual *NIX micro-kernel.

You are viewing this file from within a POSIX-adjacent shell.

What you type is run as a command.

The prompt shows your user, host, and current directory and is configureable via
PS1.

Common commands:

  ls          list files in the current directory
  cat FILE    print a file's contents
  cd PATH     change directory
  pwd         show current directory
  echo TEXT   print text
  man CMD     read the manual for a command

Tools you might reach for:

  printf             formatted output
  grep               search text
  head, tail         show the start or end of a file
  touch, rm, mkdir   create and remove files and directories

That's the floor.  Everything else is discoverable by running
commands and reading errors.

HINT: should you hit a standalone '>' prompt, there is an unclosed quotation
      lingering somewhere.

HINT: You can discover more commands by exploring the directories listed under
      the PATH environment variable.
