echo ruby capitalize

This is how you should push a string in a command's stdin.

Don't do this: echo word | command Using a bash "here strings" and "here documents" look leeter than piping echo into the command. Also prevents subshell execution. Word is also expanded as usual.
This is sample output - yours may be different.

Capitalize first letter of each word in a string - A ruby alternative

"-n" loops around ; "-e" executes the given quoted string ; "$_" is the current line ; "split" creates an array on white space; each item of the array is "collected" to be then "capitalized" ; the array is "joined" back into a string.
This is sample output - yours may be different.
