I have a file with several lines.
When using cat/more/less [file] in the shell,
the content is shown line by line
When doing the following commands:
temp=`cat [file]`
echo $temp
the content is shown in one line.
Is there a way to preserve the line endings when setting to environment variable and then echo it?
Thanks

The Proper Way to Preserve Linebreaks The right way to use a variable is simple: quote the variable. This is because if we quote a variable, the shell will treat it as one single argument to the command, no matter if the variable contains linebreaks or not.
Manipulating your PATH variable To make the change permanent, enter the command PATH=$PATH:/opt/bin into your home directory's . bashrc file. When you do this, you're creating a new PATH variable by appending a directory to the current PATH variable, $PATH . A colon ( : ) separates PATH entries.
Yes:
temp=`cat [file]`
echo "$temp"
The magic is in the quotes around $temp; without them, echo gets these arguments:
echo line1\nline2\nlin3
The shell parsing algorithm will split the command line at white space, so echo sees three arguments. If you quote the variable, echo will see a single argument and the shell parsing won't touch the whitespace between the quotes.
