linux - 批处理模式 SSH 给出错误 "TERM environment variable not set"

Question

我确保在 .bashrc 中定义了 TERM。

但是，当以批处理模式运行 ssh 时，我得到:

 $ ssh pc-lab7 "echo $TERM; echo $0"
    TERM environment variable not set.
    linux
    -bash

如果我在交互模式下运行 ssh，我不会看到这个错误。

如何消除此错误消息？

使用-t选项给ssh分配tty

 -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.
