Pattern: Unescaped single quote in shell script
Issue: -
In POSIX shell, the shell cares about nothing but another single quote to terminate the quoted segment. Not even backslashes are interpreted.
Enclosing characters in single-quotes ( '' ) shall preserve the literal value of each character within the single-quotes. A single-quote cannot occur within single-quotes.
Example of incorrect code:
echo 'This is not how it\'s done'.Example of correct code:
echo 'This is how it'\''s done'.If you want your single quoted string to end in a backslash, you can rewrite as 'string'\\ or ignore this warning.
