ssh 和脚本问题

Question

我在执行 ssh 时遇到了一个奇怪的问题。我不确定无与伦比的`这个词是从哪里来的。我需要做的是运行脚本，将我在终端上执行的操作的信息记录到文本文件中。 ssh 之后 -

ATTENTION:
Unsecure Telnet and FTP will be turned off soon.
Please make arrange to use ssh or sftp.
Putty(telnet) and WinSCP(ftp) would be a good replacement.


Unmatched `
d13.ucs.louisiana.edu% bash
bash-2.04$ script -a myInformation.txt
Script started, file is myInformation.txt
Unmatched `
d13.ucs.louisiana.edu%

当我尝试启动名为 myInformation.txt 的脚本时，您可以看到我收到的消息 - 脚本已启动，文件为 myInformation.txt。但正如您所注意到的，我再次收到消息 Unmatched ` 并且来自 bash。问题是什么 ？任何建议的见解都会非常好。

注意：名为 myInformation.txt 的文件正在创建，但没有任何内容进入其中。因为我什至尝试运行某些命令，例如 ls，然后使用 ctrl+d 退出脚本。但当我打开文件时，什么也没有。

Answer 1

额外的 ` 似乎就在 .cshrc 的开头。

...当然，如果您像您所说的那样运行 bash，则除外。 ps 的输出是什么？
