  Thanks, I hate it.
  
  A while ago I wrote a window manager in nothing than POSIX sh and POSIX utilities: https://git.qtp2t.club/hazel/wmrc. This taught me to never write shell in an extended capacity again, especially after I forgot to define a variable and it wiped $HOME.

    yea, POSIX shell isn’t exactly a good language to write a nontrivial program in. But I thought I’d share it here anyway, seeing people implement stuff in esoteric languages is always fun :)

  What came first, the (shitty 😏) name, or the idea?

  I’m a bit confused.
  
  For example is using $(()) which is a bashism, I’d assume
  
  (almost) entirely written in POSIX shell
  
  means using some external tools (like od), not relying on non-POSIX features.

    $(()) is not a bashism.

    od is also POSIX.

      You are right.
      
      Thanks for the correction. I misread a table, clear sign I never used arithmetic expressions before.
