比较两个文件夹找出不同的文件，并按路径复制到另外一个文件夹(shell练习记录1)

本文记录下，曾经使用的sh脚本之一，时间太久忘完了，记录下。

#!/bin/bash

#
#example to use this script.
#source to_find_prop_files.sh ~/workspace/org_source_code/out ~/workspace/tsrc_code/out~/workspace/to_vrz_src_code/out
#arg1's src is contain main files more libs
#arg2's src is not contain vendor path.
#the result path is current path
#功能：比较参数1，2两个路径中到文件，把参数1路径多出到文件，按完整路径，拷贝到result目录下
#

dir="result"
dir1=$1
dir2=$2

if [ -e $dir ]; then
	rm -rf $dir
	echo "remove old result and create newer!"
	mkdir $dir
	touch $dir/same_path.log
	touch $dir/props_files.log
else
	echo "create result path!"
	mkdir $dir
	touch $dir/same_path.log
	touch $dir/props_files.log
fi

function find_props(){
	for element in `ls $1`
		do
			dir1_or_file=$1"/"$element
			if [ -d $dir1_or_file ]; then
				dir2_or_file=$2"/"$element
				if [ -e $dir2_or_file ]; then
					find_props $dir1_or_file $dir2_or_file
				else
					sub_path=$dir"/"$2
					mkdir -p $sub_path
					cp -rf $dir1_or_file $sub_path
					echo "$dir1_or_file" >> $dir/props_files.log
				fi
			else
				file2=$2"/"$element
				if [ -e $file2 ]; then
					echo "$file2" >> $dir/same_path.log
				else
					sub_path=$dir"/"$2
					mkdir -p $sub_path
					cp -rf $dir1_or_file $sub_path
					echo "$dir1_or_file" >> $dir/props_files.log
					echo "copy new files please wait..."
				fi
			fi
		done

}

find_props $dir1 $dir2

保存为.sh即可。在linux系统下使用。
