参数内的主目录扩展 (~)
当我输入以下内容（BASH）时：
rdesktop -r disk:bacon=~/bacon host
它不会扩展为
rdesktop -r disk:bacon=/home/me/bacon host
似乎“磁盘：”部分是问题所在，如：
$ echo bacon=~/bacon disk:bacon=~/bacon
bacon=/home/me/bacon disk:bacon=~/bacon
How can I make tilde Expand?
When I enter the following (BASH):
rdesktop -r disk:bacon=~/bacon host
It does not expand to
rdesktop -r disk:bacon=/home/me/bacon host
It seems the "disk:" part is the problem as can be seen in:
$ echo bacon=~/bacon disk:bacon=~/bacon
bacon=/home/me/bacon disk:bacon=~/bacon
How can I make tilde expand?

虽然 ~ 不会扩展（它用作路径的特殊路由），但
$HOME会扩展。但要小心改变环境的
su！While ~ does not expand (it's used as specially routed of the path),
$HOMEdoes.But be careful with environment-changing
su!rdesktop -r disk:bacon=$(echo ~/bacon) host就可以了。它不会让人赏心悦目，但它会起作用。
rdesktop -r disk:bacon=$(echo ~/bacon) hostwill do it. It won't please the eye, but it will work.
