system函数使用介绍
#!/usr/bin/perl -w $stant=system("ls"); print "$stant\n"; $well=system "'date'"; print "three:$well\n-------------\n"; @hello=("echo","hello,world!"); system(@hello);
`` 也可以用的
一个简单的例子:
#!/usr/bin/perl -w @a=`ls /root` ; foreach ( @a ) { print $_ ; }
直接输出
print `ls /root`;

the cling of it!
