How can I export something that's multiline?

export foo='bar  a ab          ai   ii              bar'

and put that on two different lines without a newline literal?

export foo='bar  a ab          ai 

  ii              bar'

perhaps with a backslash?

export foo='bar  a ab          ai 

  ii              bar'

is this safe?

Using within a single-quote block clearly doesn't work.

$ export foo='bar  a ab          ai

  ii              bar'

$ echo "$foo"

bar  a ab          ai

  ii              bar

You could use double quotes.

$ export foo="bar  a ab          ai

  ii              bar"

$ echo "$foo"

bar  a ab          ai  ii              bar

Or you could put it outside of the single quotes.

$ export foo='bar  a ab          ai'

'  ii              bar'

$ echo "$foo"

bar  a ab          ai  ii              bar

I'm not sure what you mean by "safe".

  @AlexanderMills What specifically do you mean by "always works"? This will always work for two strings.
