title: How do I grep for strings with special characters like []?
body: <p>I am trying to find all the files has text: <code>$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']</code>,  I tried to use <code>grep -rl '$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']' .</code>, but later on found <code>[]</code> has special meaning as search pattern. So what is the right command for searching text <code>$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']</code>?</p>
