我的控制台画线有问题。问题是当我通过 ssh 连接到服务器时一切正常。但是，当我使用向上箭头键显示上次使用的命令时，它通常会在$符号后留下几个字符：
user@host:~$ cd /var/www_vhosts/
user@host:/var/www_vhosts$ ls -la instalator-paczek/
razem 16
drwxrwxr-x 3 root root 4096 02-20 10:48 .

drwxrwxr-x 2 user developers 4096 05-29 11:03 logi
user@host:/var/www_vhosts$ cd instalator-paczek/
user@host:/var/www_vhosts/instalator-paczek$ nano instalator-paczek.sh
user@host:/var/www_vhosts/instalator-paczek$ cp -r inst

# here I use up arrow key to display last used commands and everything is ok until it show last: "cp -r in..." command
# "cp -r inst" is shown and next last used commands are shown after those 10 characters. I displays them like:
# $ cp -r instls -la
# $ cp -r instcd directory
# etc.
# I tried using backspace but it clear characters just until "cp -r inst", not even one more
# prompt is shown correctly only after i press enter or ^C
user@host:/var/www_vhosts/instalator-paczek$ cp -r instnano /etc/issue
user@host:/var/www_vhosts/instalator-paczek$ ls
instalator-paczek.sh logi
更令人恼火的是，当我输入的字符多于控制台宽度时会发生什么。光标以某种方式返回到行首并覆盖提示：
/d/asd/as/d/asd/asd/as/d/asd/asdww_vhosts/instalator-paczek$ ls -la asdkasdasdasd/asdasdasd/asdasdasdasdasdas/dasdsdaas/d/asd/as/d/asd/as
我无法使用任何长命令，因为它会覆盖开头，而且我无法查看我是否正确输入了所有内容。即使显示损坏，粘贴到控制台内的长命令也可以工作。就像只有显示损坏但命令本身没问题。
我有 ubuntu 12.10 并用作Konsole控制台应用程序。服务器上有Debian GNU Linux 6.0xterm。
user@host:/var/www_vhosts/instalator-paczek$ echo $TERM
xterm
它只发生在这台服务器上，我连接的其他服务器运行良好Konsole。
如何解决这个问题？

发生这些错误是否可能是因为服务器上没有xterm安装并且没有调整大小命令？

似乎调整控制台窗口的大小也会发生变化stty。

我已经xterm在服务器上安装了软件包。我已经注销并再次登录，但问题仍然相同。安装后我应该重新启动服务器xterm吗？

好吧，我终于找到了解决方案。问题是$PS1没有用 和 括起来的颜色\[序列\]。更正前$PS1是：
export PS1='\e[1;32m\u@\h:\w$ \e[m'
修复后：
export PS1='\[\e[1;32m\]\u@\h:\w$ \[\e[m\]'
