Single quotes
Using single quotes, we could write the commands like this, which is perhaps more readable than the backslashes version, and creates files with identical names:
$ touch 'important files' $ touch 'Testfile<Tom>.doc' $ touch 'Review;Final.doc' $ touch '$$$Money.doc'
Unlike backslashes, single quotes can escape a newline in a word:
$ echo 'quotes > foo > bar' quotes foo bar
How do we use a single quote (') as a literal character between two single quotes? If you are coming to Bash from a language such as Perl or PHP, you might try it like this, with a backslash, but that doesn't work:
$ echo 'It\'s today' >
This is because backslash is not treated specially within single quotes. Doubling the single quote doesn't work, either:
