Code Golfing Split String in Bash [closed]

Question

Let us play a little golfing game. Given a single line of N space separated numbers from STDIN, one must output those numbers on N lines.

So far, I came up with the three following bash solutions :

• xargs -n1 (9)
• tr \ \\n (8)
• fmt -1 (6)

Can anyone do better? I am eager to learn new tricks

Bash (22)

read X;printf %d\\n $X  (thanks to manatwork but without literal NL)

30 read -aX;printf "%d\n" ${X[*]} 26 read X;echo -e ${X// /\n} 28 printf "%d\n" $(</dev/stdin) 27 printf "%d\n" $(</dev/fd/0) 26 printf %d\n $(</dev/fd/0) 23 read X;printf "%d\n" $X
