PHPSeclib使用写操作的附加换行符

对于通过SSH编辑文件的特定用例，我即将简单地将其移回PERL。似乎无论我做什么，都会在文件中放置额外的换行符。示例变量具有以下特性：

req_extensions = v3_req
prompt = no
[req_distinguished_name]
C = US

使用下面的命令，我得到下面的输出

$ssh->write("echo '$file' > /directory/test.txt\n");

导致：

req_extensions = v3_req

prompt = no

[req_distinguished_name]

C = US

编辑并添加相关调试日志：

只要传递
-n
，它就会解决这个问题


$ssh->write（“echo-n'$file'>/directory/test.txt\n”）；

-n
告诉不要追加新行。
我不确定
write（）
为什么要发送额外的换行符。我确信如果我一行一行地添加到该文件中，就会起作用。最后，我简单地使用了
SFTP:：put（）
，它允许我将
@
放在
SSH:：exec（）
无法使用的地方。感谢所有的输入-这是一个与我所希望的略有不同的方法，但它可以工作。
您想删除新行还是想添加新行？我不想添加实际上不在字符串中的额外换行符。我想需要查看该字符串变量的十六进制？可能是CR和LF？您在该命令的末尾添加了
\n
。删除它，它将删除换行符。您的命令可以是
$ssh->write（“echo'$file'>/directory/test.txt”）^对此也感到奇怪。这不会让你得到
test.txtn
？根据
echo
手册页，结果与以前相同<代码>-n
应该可以解决这个问题。虽然它对我有用。请参阅我的要点。我在这里找到了类似问题的解决方案。如果
write
方法有任何问题，您可以使用
exec（）
方法。还有，你的远程服务器的操作系统是什么？太棒了。。为什么不使用
put
？
