不会分配伪终端，因为 stdin 不是终端 [英] Pseudo-terminal will not be allocated because stdin is not a terminal

问题描述

我正在尝试编写一个 shell 脚本，在远程服务器上创建一些目录，然后使用 scp 将文件从我的本地机器复制到远程服务器上.这是我到目前为止所拥有的:

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

每当我运行它时，我都会收到此消息:

Whenever I run it I get this message:

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

脚本永远挂起.

我的公钥在服务器上是可信的，我可以在脚本之外运行所有命令就好了.有什么想法吗?

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 ssh -t -t(或简称 ssh -tt)强制伪 tty即使 stdin 不是终端也分配.

Try ssh -t -t(or ssh -tt for short) to force pseudo-tty allocation even if stdin isn't a terminal.

另见:终止由 bash 脚本执行的 SSH 会话

来自 ssh 联机帮助页:

From ssh manpage:

-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.
