SSH remote server - display only "echo" on output in terminal
提问by kevas
I have bash script (for example):
我有 bash 脚本（例如）：
ssh -t -t [email protected] << EOF
cd /home/admin
mkdir test
echo 'Some text'
exit
EOF
Can I display only "echo" command in terminal? It is possible?
我可以在终端中只显示“echo”命令吗？有可能的？
Now all commands are displayed.
现在显示所有命令。
Thank you
谢谢

Specifying the commands on standard input with ssh -tcauses the commands to be echoed back, but you don't have to do that.
在标准输入上指定命令 withssh -t会导致命令被回显，但您不必这样做。
ssh -t [email protected] "
cd /home/admin
mkdir test
echo 'Some text'"
(The exitisn't really required or useful, so I left it out.)
（这exit不是真正需要或有用的，所以我把它省略了。）
Use single quotes if you want to prevent the local shell from interpolating variables etc in the string containing the commands.
如果要防止本地 shell 在包含命令的字符串中插入变量等，请使用单引号。
To selectively display an individual command as well as its output, you can use something like
要选择性地显示单个命令及其输出，您可以使用类似
sh -vc 'echo \"Some text\"'
although the nested quoting can start getting on your nerves pretty quickly.
尽管嵌套引用很快就会让您感到不安。
