hi everyone, how could I store the output of command substitution into an array
lets say I have the following output

Code:

var=$(du -h | sort -hr | grep ./ | head -3)

but this stores everything into $var, so when I output the content of $var, it shows everything in one line. How could I do stdout so it shows
size file
size file
size file

Use double quotes around $var

Code:

bash-4.2$ echo "$var"
2.4G	./Downloads
1.3G	./Documents/Documents
1.3G	./Documents
