PHPSeclib使用写法的其他换行符

对于通过SSH编辑文件的特定用例，我已经将其简单地移回PERL了。看来不管我做什么，都会在文件中放置其他换行符。示例变量具有以下内容：

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

使用以下命令，我得到下面的输出

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

结果：

req_extensions = v3_req

prompt = no

[req_distinguished_name]

C = US

编辑添加相关的调试日志：

答案 0 :(得分：1)

只需通过 $ssh->write("echo -n '$file' > /directory/test.txt\n"); ，它就可以解决此问题。

-n

{{1}}告诉不要添加新行。

答案 1 :(得分：0)

我不确定write()为什么要发送其他换行符。我确定我是否一行一行地添加到本来可以工作的文件上。最后，我只使用了SFTP::put()，就可以放置@不能与SSH::exec()一起使用的内容。感谢您的所有输入-这与我想要的方法有点不同，但是可以。
