在使用某些软件时，在输入如：--prefix=/some-path<tab>之后就会变为 /some-path，前面的--prefix=消失了!!!...
也就是说只要在符号'='后按tab补全时，=前面的字符就会消失。
具体的操作在附件有个gif文件。
猜想：
我认为是bash-completion的设置问题，但是今天琢磨了一下午没有结果。
然后我把.bashrc中下面的：
代码： 全选
# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
fi这不是一个好的解决办法，希望大家可以帮忙看下。
谢谢大家！

Description: programmable completion for the bash shell
bash completion extends bash's standard completion behavior to achieve
complex command lines with just a few keystrokes. This project was
conceived to produce programmable completion routines for the most
common Linux/UNIX commands, reducing the amount of typing sysadmins
and programmers need to do on a daily basis.
