如何仅卸载Libre Office的一个版本？

Question

我已经安装了Libre Office的两个版本- 4.3和默认的：

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

显示

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
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

我只想要libreoffice4.3-*而不是libreoffice^/(?!4.3)-*

在apt-get命令中有使用这种正则表达式的方法吗？

Answer 1

apt-get接受POSIX (不是shell风格的通配符)：

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

将移除

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

以及那些依赖他们的人。(这就是为什么apt-get remove libreoffice4*不像你想的那样做。)

所以试着：

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

它将删除：

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

来自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.
