I find it useless but definitely simpler than #9230
There is 1 alternative - vote for the best!
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.
Capitalize first letter of each word in a string.
"-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.
If you can do better, submit your command here.

I get
sh: Syntax error: redirection unexpectedwhen I try this command.
9230 and 9232 make the first letter of each word capital AND the subsequent letters lower case. Your alternative leaves the subsequent letters capital. In other words theirs converts 'fOo baR' to 'Foo Bar' and yours converts to 'FOo BaR'.
