<h3 class="section">3.6 Basic vs Extended Regular Expressions</h3>
-<p><a name="index-basic-regular-expressions-239"></a>

In basic regular expressions the meta-characters ‘<samp><span
class="samp">?</span></samp>’, ‘<samp><span
class="samp">+</span></samp>’,
‘<samp><span class="samp">{</span></samp>’, ‘<samp><span
class="samp">|</span></samp>’, ‘<samp><span
class="samp">(</span></samp>’, and ‘<samp><span
class="samp">)</span></samp>’ lose their special meaning;
instead use the backslashed versions ‘<samp><span
class="samp">\?</span></samp>’, ‘<samp><span
class="samp">\+</span></samp>’, ‘<samp><span
class="samp">\{</span></samp>’,
‘<samp><span class="samp">\|</span></samp>’, ‘<samp><span
class="samp">\(</span></samp>’, and ‘<samp><span
class="samp">\)</span></samp>’.

+ <p><a name="index-interval-specifications-244"></a>Traditional <samp><span
class="command">egrep</span></samp> did not support the ‘<samp><span
class="samp">{</span></samp>’ meta-character,
and some <samp><span class="command">egrep</span></samp> implementations
support ‘<samp><span class="samp">\{</span></samp>’ instead, so
portable scripts should avoid ‘<samp><span
class="samp">{</span></samp>’ in ‘<samp><span class="samp">grep
-E</span></samp>’ patterns and
should use ‘<samp><span class="samp">[{]</span></samp>’ to match a
literal ‘<samp><span class="samp">{</span></samp>’.
