Question

1)For example::I have a $string ="abc hell_+o w343r2d -000 rebotin".Using search pattern and regular expression is there any way to remove or chop -000 from the string in PERL. 2)I want to begin learning regular expression with examples in simple means.Which is the best tutorial to start with???

Answer 1

$string = "foobar";
$string =~ s/bar/baz/g;

http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=search+and+replace” rel=“nofollow noreferer” 研究和替代。第一个项目是寻找,第2项是用什么来取代。

就你而言,你要求删除替代条款。 <代码>string =~ s/000/g将完全删除-000。
