Linux - Line continuation character backslash

In Unix-based systems like Linux, backslashes " \ " are used as line continuation characters. They indicate that the command continues on the next line, allowing a long command to be split across multiple lines for better readability. For example:

vManage1:~$ openssl req -x509 -new -nodes -key ROOT-CA.key -sha256 -days 3652 \
-subj "https://cdn.networklessons.com/C=NL/ST=NL/O=nwl-lab- \ sdwan/CN=vmanage1.lab.nwl.ai" \
-out ROOT-CA.pem

should actually be input like this:

openssl req -x509 -new -nodes -key ROOT-CA.key -sha256 -days 3652  -subj "https://cdn.networklessons.com/C=NL/ST=NL/O=nwl-lab-sdwan/CN=vmanage1.lab.nwl.ai" -out ROOT-CA.pem
