背景
如何将程序依赖的动态库拷贝到指定的目录？
例子
- 通过LDD查看依赖的动态库。
bash
$ ldd extract_gpu

vi release.sh
#!/bin/bash
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。
-
创建目标目录
mkdir release
-
将postgres依赖的动态库拷贝到目标目录
bash release.sh extract_gpu ./release/
bash
ll ./release
