Elegant Bash Conditionals

Re:Elegant Bash Conditionals by pizza234 on Tuesday March 02, 2021 @02:18PM (#26319192)

The traditional format of Bash's if/then has `if` and `then` on separate lines:

    if command_or_condition
    then
      branch
    fi

I suppose that to many, this looks wasteful and consequently ugly, so one looks for alternatives.

I always inline the `then`, which requires a semicolon:

    if command_or_condition; then
      branch
    fi

If I was forced to use the traditional format, I'd be definitely annoyed :)

I use:

  if command_or_condition
  then branch
       more_branch
  fi

Given the relationship between ; and newline, and the positions of required ;s in if/then/fi, I assumed that was intended.

How swapping a '\n' char for a ';' is less "wasteful" or "ugly"?
