我运行一个简单的程序:
my $_ = '/login/.htaccess/.htdf';
s!(/\.ht.*?)$!/!;
print "$_ $1";
Run Code Online (Sandbox Code Playgroud)
OUT
/login/ /.htaccess/.htdf
我希望这个正则表达式只匹配/.htdf.
例2:
my $_ = 'abcbc';
m/(b.*?)$/;
print "$_ $1\n";
Run Code Online (Sandbox Code Playgroud)
OUT
abcbc bcbc
我期待bc.
为什么*?还贪心?(我想要最小的比赛.)
我想这取决于背景.
