如何将程序依赖的动态库拷贝到指定的目录？
例子
1、通过LDD查看依赖的动态库。

2、写一个SHELL脚本，自动拷贝依赖的动态库。
vi test.sh
deplist=$( ldd $1 | awk '{if (match($3,"/")){ print $3}}' )
cp -L -n $deplist $2
-L 表示拷贝文件（如果是软链，会拷贝到最终的文件）。
-n 表示不覆盖已有文件。
3、创建目标目录。
mkdir /tmp/lib
4、将postgres依赖的动态库拷贝到目标目录
. ./test.sh /usr/pgsql-10/bin/postgres /tmp/lib/
ll /tmp/lib
