changing quotes to single quotes

[GentleInfant]

When dealing with special characters the lesson advises to use quotes, however single quotes is the safer option. For example

touch \$HOME
ls "$HOME" # lists the contents of the home directory
ls '$HOME' # lists the '$HOME' file

Thanks. As per , this is good. Due to time constraints, it is unlikely this can be discussed. Perhaps adding a link to the documentation is helpful?
