【2】how to show a package depends and reverse depands in centos (yum)

yum deplist <package_name>

repoquery --requires --recursive <package_name>

想升级系统自带的库，看那些库依赖或者bin文件依赖该库

检查/usr/bin /usr/sbin/ /usr/lib64/:

find . *.so* | xargs -I {} bash -c "echo '**** {} *****'; ldd {} | grep libtasn" 2>1 | grep -E '^\s*libtasn' -B 1

另外一种方式：

rpm -qa > list.txt; for line in $(cat list.txt) ; do echo ">>>$line"; rpm -qR $line;  done > deps.txt; grep -E '>>>|curl' deps.txt 

【3】how to show a package depends and reverse depands in debian (apt)
