| Nov 4, 2016 at 14:45 | comment | added | user232326 | @don_crissti The original answer: echo $(tac -s" " <<< $VAR) does not have a trailing space because the $(…) removes trailing newlines and spaces if the IFS has them. My solution will be corrected soon, thanks. | |
| Nov 4, 2016 at 13:15 | comment | added | Stéphane Chazelas | With the current tac -s" " <<< "$VAR " version, it still inserts a leading blank line, adds a trailing space and omits the trailing newline character (as if printf '\n%s ' "$reversed_VAR" instead of expected printf '%s\n' "$reversed_VAR") | |

| Nov 3, 2016 at 23:16 | comment | added | user232326 | @JhonKugelman Without the echo, the output has an additional newline, equivalent to this: echo $'100 \n90 80 70 60 50 40 30 20 10' | |
