Shell script extracts files recursively from folders

Demand

The first two days encountered the need to extract files in a folder of about 10 levels, and then wrote this script.

A file structure such as the following:

    Dir1    ├──a    │   ├──b    │   │   └──file1    │   └──file2    ├──c    │   └──d    │       ├──e │ │   └──file4    │       └──file3    └──file5

We need to extract the file1~file5 and put it in another folder.

Script

The script getfilefromdir.sh is as follows:

#!/bin/Bash#desc:getfilefrom Directory#author: Ten years later Brother Lou (http://www.cnblogs.com/lurenjiashuo/)#example:SHGetfilefromdir.SHA Binit_path=${1%/}Save_path=${2%/}functionChecksavepath () {if[ -d $SAVE _path] Then        RM-RF $SAVE _pathfi    mkdir${save_path}Touch$SAVE _path".

Log" 2>&1            fi        fi     Done}checksavepath forSfolinch${init_path} DoGetfilefromdir ${sfol} Done

Run

sh getfilefromdir. SH dir1/dir2

The first parameter is the source folder, and the second is the target folder (you do not need to create it in advance).

If there is a file with the same name, there will be Dir2.log

The result is:

Dir2├──file1├──file2├──file3├──file4└──file5
