[SOLVED] Reading a file into variable without newlines

Issue

I am not expert with bash but I would imagine this would be a simple script. I am trying to read a file with a few lines into a single bash variable without the new lines.

My current script reads them in but keeps the presence of newlines

options=$(<vm.options)
echo "$options"

The file looks something like this:

-Random 1
-Letters2
-Occur 3
-In
-Passwords9

The script would read this into a variable where its output would look like:

-Random 1 -Letters2 -Occur 3 -In -Passwords9

Solution

You can simply replace the new line with tr :

options=$(cat lf | tr -s '\n' ' ')
