查询Linux某命令来自哪个包

Debian：（Ubuntu等）

先安装apt-file

sudo apt-get install -y apt-file
apt-file update

查询命令：(已查询ifconfig为例)

root@debian ~ # apt-file search bin/ifconfig
net-tools: /bin/ifconfig

apt-file search -x(--regexp) 后可接正则表达式，如：

root@deepin ~ # apt-file search -x 'bin/rz$'
lrzsz: /usr/bin/rz
root@deepin ~ # apt-file search --regexp 'bin/rz$'
lrzsz: /usr/bin/rz

CentOS：

root@CentOS7 ~ # yum provides *bin/ifconfig
