Capture Telnet output to a file by running in the background
提问by neo
I am having a linux powered board on which I wanted to capture the telnet output to a file. I tried doing it as shown below-
我有一个 linux 驱动的电路板，我想将 telnet 输出捕获到一个文件中。我尝试这样做，如下所示 -
telnet localhost xxxx >> /mnt/sd-xxx/log/file.txt &
as well as
也
telnet localhost xxxx | tee /mnt/sd-xxx/log/file.txt &
and
和
telnet localhost xxxx -f /mnt/sd-xxx/log/file.txt &
But it's unable to go in background in all of the above cases. I also tried to keep it in a script,but this also doesn't work and the program crashes. How can I capture the telnet output and redirect to a file by running it as a background process.
但在上述所有情况下都无法进入后台。我也尝试将它保存在脚本中，但这也不起作用并且程序崩溃了。如何捕获 telnet 输出并通过将其作为后台进程运行来重定向到文件。
Thanks in Advance.
提前致谢。

Have you tried curl?
你试过卷曲吗？
curl telnet://localhost:xxxx >> /mnt/sd-xxx/log/file.txt &
