请大家帮我写一个perl代码。就是处理掉上面每一行的最后一个含行符,使这些字符之间无空格,谢谢大家啊!
例如上面的东西在一个名字叫test的文件中,代码如下:
#!/usr/bin/perl
$filename = 'test';
unless ( open(TESTFILE, $filename) ) {
print "Cannot open file \"$filename\"\n\n";
exit;
}
@file = <FILEHANDLE>;
close TESTFILE;
$result = join( '\n', @file);
$result=~ s/\s//g;
.....
我下面不会写了,如何让$result内容写入到一个文件中呢!
