• Command mode:

  dsh -c "echo hi" => prints "hi" and exits

• Comments for shell scripting, just start them with a `#`
• Builtins! No more executing a whole other program just to do simple stuff like printing text; the following commands are now built into the shell:
  • `:`: nop
  • `source`: evaluates the given file; a proper `./` construct will be added soon
  • `eval`: complete passed command / script
  • `exec`: complete the passed command and exit with the same exit code
  • `echo`: POSIX compliant echo command
  • `exit`: Guess.

• Multiple commands in a single line, delimited by semicolons:

  echo hi; echo hello => hihello

• Short-circuiting and and or operators:
• In file test.lua:

  error()

     test && echo hello =>
     test || echo hello => hello
  echo hi || echo hello => hi

• Command expansion:

  $(command) or `command`

• Arithmetic expansion:

  $((expression))

• Shell scripting
• POSIX compliance
