伪终端将不被分配，因为标准输入不是终端 [英] Pseudo-terminal will not be allocated because stdin is not a terminal

问题描述

我试图写一个远程服务器上创建一些目录中的shell脚本，然后使用SCP从我的本地计算机中复制文件远程到。这是我到目前为止有：

I am trying to write a shell script that creates some directories on a remote server and then uses scp to copy files from my local machine onto the remote. Here's what I have so far:

ssh -t user@server<<EOT
DEP_ROOT='/home/matthewr/releases'
datestamp=$(date +%Y%m%d%H%M%S)
REL_DIR=$DEP_ROOT"/"$datestamp
if [ ! -d "$DEP_ROOT" ]; then
    echo "creating the root directory"
    mkdir $DEP_ROOT
fi
mkdir $REL_DIR
exit
EOT

scp ./dir1 user@server:$REL_DIR
scp ./dir2 user@server:$REL_DIR

每当我运行它，我得到这个消息：

Whenever I run it I get this message:

Pseudo-terminal will not be allocated because stdin is not a terminal.

和脚本只是挂起，直到永远。

And the script just hangs forever.

我的公共密钥被信任的服务器上，我可以运行该脚本只是罚款之外的所有命令。任何想法？

My public key is trusted on the server and I can run all the commands outside of the script just fine. Any ideas?

推荐答案

尝试的ssh -t -t 来迫使伪终端分配，即使标准输入不是终端

Try ssh -t -t to force pseudo-tty allocation even if stdin isn't a terminal.

参见：<一href=\"http://stackoverflow.com/questions/7085429/terminating-ssh-session-executed-by-bash-script\">Terminating SSH会话通过bash脚本

从SSH手册页：

-T      Disable pseudo-tty allocation.

-t      Force pseudo-tty allocation.  This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing
         menu services.  Multiple -t options force tty allocation, even if ssh has no local tty.
