\subsection quotes Quotes
Sometimes features such as <a href="#expand">parameter expansion</a> and <a href="#escapes">character escapes</a> get in the way. When that happens, the user can write a parameter within quotes, either `'` (single quote) or `&quot;` (double quote). There is one important difference between single quoted and double quoted strings: When using double quoted string, <a href="#expand-variable">variable expansion</a> still takes place. Other than that, a quoted parameter will not be parameter expanded, may contain spaces, and escape sequences are ignored. The only backslash escape accepted within single quotes is `\'`, which escapes a single quote and `\\`, which escapes the backslash symbol. The only backslash escapes accepted within double quotes are `\&quot;`, which escapes a double quote, `\$`, which escapes a dollar character, `\` followed by a newline, which deletes the backslash and the newline, and lastly `\\`, which escapes the backslash symbol. Single quotes have no special meaning within double quotes and vice versa.

There is one important difference between single quoted and double quoted strings: When using double quoted string, <a href="#expand-variable">variable expansion</a> still takes place. Other than that, no other kind of expansion (including <a href="#expand-brace">brace expansion</a> and parameter expansion) will take place, the parameter may contain spaces, and escape sequences are ignored. The only backslash escape accepted within single quotes is `\'`, which escapes a single quote and `\\`, which escapes the backslash symbol.
