我怎样才能只卸载 Libre Office 的一个版本？

我安装了两个版本的 Libre Office - 4.3 和默认版本：

dpkg --get-selections | grep -v deinstall | grep libreoffice

我只想要libreoffice4.3-*，却不想要libreoffice^/(?!4.3)-*

有没有办法在命令中使用这种正则表达式apt-get？

答案1

apt-get接受 POSIX 正则表达式（不是 shell 样式的通配符）：

sudo apt-get remove '^libreoffice4.3-*'

将删除

libreoffice4.3
libreoffice4.3-base
libreoffice4.3-calc
libreoffice4.3-debian-menus
libreoffice4.3-dict-en
libreoffice4.3-dict-es
libreoffice4.3-dict-fr
libreoffice4.3-draw
libreoffice4.3-en-us
libreoffice4.3-impress
libreoffice4.3-math
libreoffice4.3-ure
libreoffice4.3-writer

以及那些依赖它们的程序。（这就是为什么apt-get remove libreoffice4*它没有按照你想象的那样运行。）

因此尝试一下：

sudo apt-get remove '^libreoffice-.*' libreoffice

这将删除：

libreoffice-avmedia-backend-gstreamer
libreoffice-base-core
libreoffice-calc
libreoffice-common
libreoffice-core
libreoffice-draw
libreoffice-help-en-gb
libreoffice-help-en-us
libreoffice-impress
libreoffice-l10n-en-gb
libreoffice-l10n-en-za
libreoffice-math
libreoffice-pdfimport
libreoffice-style-galaxy
libreoffice-writer
libreoffice

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.
