从ldd输出中复制所有共享对象

问题描述

如何从可执行文件的ldd输出中复制所有共享对象？

我正在寻找类似的东西，但这是给find的，我需要ldd：

find -name "*python3.7*" -exec cp "{}" /home/user/python/arm-linux-gnueabihf/ \;

解决方法

上面的示例ldd输出已保存到“ infile”。说明：运行awk选择具有4个字段的行，然后运行echo一个将lib从第三个字段复制到目标目录的命令：

awk 'NF == 4 { system("echo cp " $3 " destdir") }' infile

与其从infile中读取，不如将ldd的输出通过管道传输到awk，例如：

ldd 0_FULL_GAME | awk 'NF == 4 { system("echo cp " $3 " destdir") }'

用您选择的目录替换destdir。一旦显示的命令看起来确定，请删除echo以进行实际复制，例如：

ldd 0_FULL_GAME | awk 'NF == 4 { system("cp " $3 " chosen-dir") }'
