Perl学习笔记

open TXT,">t4.txt";

print TXT "你下辈子做猪。";

open TXT,">>t6.txt";

print TXT "你是你是你是";

close TXT;

close TXT;

close TXT;

open TXT,"t4.txt";

my $w=<TXT>;

open TXT,"t6.txt";

my $d=<TXT>;

open TXT,">>t5.txt";

print TXT "$w";

print TXT "$d";

close TXT;

close TXT;

close TXT;

8、将t1.Txt、t2.txt、t3.txt三个文件中的内容用其他数据代替，然后将t1.txt和t2.txt里面的内容放入t3.txt中。

#!/urs/bin/perl

open a,">t1.txt";

print a "2013";

open b,">t2.txt";

print b "0830";

open c,">t3.txt";

print c "芜湖";

close a;

close b;

close c;

open c,">>t3.txt";

open a,"t1.txt";

open b,"t2.txt";

print c "\n".<a>."\n";#.是连接符，print c <a>;是直接连接不要换行。

print c <b>."\n";

close a;

close b;

close c;

9、合并文件后删除不要的文件。

在8代码后加入如下代码：

unlink<t1.txt>;

unlink<t2.txt>;

或者

Unlink<t1.txt>,<t2.txt>;
