I have a folder containing two files
data.txt. In the bash script I have the following script
x="$(ls -l)" echo $x
The output of running this script is all on one line
total 4 -rw-rw-r-- 1 gary gary 0 Feb 9 21:52 data.txt -rw-rw-r-- 1 gary gary 21 Feb 9 22:00 scrap.sh
However, when I change the script to the one-liner
echo "$(ls -l)"
I get this
total 4 -rw-rw-r-- 1 gary gary 0 Feb 9 21:52 data.txt -rw-rw-r-- 1 gary gary 16 Feb 9 22:01 scrap.sh
Why is there a difference in the output?! The first one produces everything on one line and the next one on two separate lines. Both scripts seem to be functionally the same.
