如何删除一些包含特定关键字的包？

例如，当我想删除 Xfce 时，我这样做：

 aptitude search xfce | grep ^i

id  gtk2-engines-xfce               - GTK+-2.0 theme engine for Xfce            
id  libxfce4ui-common               - common files for libxfce4ui               
id  libxfce4util-common             - common files for libxfce4util

我想获取第二列并将它们传递给aptitude remove。 有办法吗？

apt-get支持正则表达式。只需在包名称中包含.,*或?即可使其成为表达式：

apt-get remove 'xfce.'

从man apt-get：

If no package matches the given expression and the expression
contains one of '.', '?' or '*' then it is assumed to be a POSIX
regular expression, and it is applied to all package names in the
database. Any matches are then installed (or removed). Note that
matching is done by substring so 'lo.*' matches 'how-lo' and
'lowest'. If this is undesired, anchor the regular expression with
a '^' or '$' character, or create a more specific regular
expression.
