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
