我打开了一个telnet会话，其中包含用户名和密码。我试图打开一个文件阅读，但它给了我一个错误，说“没有这样的文件或目录”，而我通过打印命令确认该文件在路径中。我们可以打开一个文件在telnet会话期间阅读吗？或者如何在telnet会话期间打开一个文件？这里是我的代码和文件是ab.txt：在perl中打开一个在telnet中读取的文件
use Net::Telnet;
$t = new Net::Telnet (Timeout => undef, Dump_log=>"dump.log");
$username="sqa";
$password="4q2013";
$t->open("xx.xx.xxxx.com");
$t->login($username, $password);
$cmd='cd '.'/projects/74/android-rfs/sys
tem/app';
my $ldir="/projects/74/Android";
ipadd();
print [email protected][2];
print "Value of \$t is:$t\n";
@lines=$t->cmd($cmd) or die "Cannot perform cmd:$!";
print @lines;
$t->cmd("cp $nmn.apklist.txt $ldir\n");
$cmd1='cd '.'/projects/74/Android';
@lines1=$t->cmd($cmd1);
print @lines1;
$req_apks="/projects/74/Android/ab.txt";
print "Value of \$req_apks is: $req_apks\n";
