将可执行文件所链接的库利用shell脚本拷贝出来

首先在嵌入式板里面通过ldd命令将可执行文件所链接的库重定向到一个文本文件。

cd /bin

ldd * >a.txt

抽取

 

#!/bin/bash

 

# version 1.0

# use for copy the exec file‘s lib to another place

 

awk '{print $3}' a.txt > lib.txt
sed -i 's/^.//g' lib.txt
number=$(wc -l lib.txt | awk '{print $1}')
echo "number is : $number"
echo "start cp now......."
n=1
while [ $n -le $number ]
do
a=$(awk "NR==$n" lib.txt)
cp $a /home/demolib
echo "copy successfully.."
n=$(($n+1))
done

echo "copy $(ls -l /home/demolib | wc -l) file"
