Hi,
I want to save command output in some variable, for example:
a=`who`
when i print this variable, there are all entries displayed on one
line, but I need each entry on a separate line.
How can I do this?

Presumably, you are using a command like this:

echo $a

When $a is expanded, each white-space-separated word becomes a
separate argument, and echo prints it arguments separated by a
space.

If you want to preserve the formatting of $a, quote it:

echo "$a"

Better still, use printf:

printf "%s\n" "$a"
