bash has mapfile... I had no idea

[Ron / BCLUG]

Today I learned about bash's `mapfile` built-in function.


Next time I want to read lines from a file to an array for processing, 
that will be choice of methods.


What a great (and surprising) utility!


Check out Dave's explanation in his 2½ minute bash video (the channel is 
highly recommended for bash tutorials):

If I had ever read about this before, I must have completely forgotten 
about it.
