learnbyexample corrected string comparison, always use quotes 
#24
https://unix.stackexchange.com/questions/131766/why-does-my-shell-script-choke-on-whitespace-or-other-special-characters

the linked issue failure corner case was when the output of command contained glob characters, for ex: `a[2]`
if string is unquoted on RHS of comparison operator, it is treated as glob comparison, not string comparison
hence why quotes are needed here
