Essay 1:shell recursively traverse a folder

Recently work required, wrote some shell scripts to do server one-click Package Update,

Traversing a folder with a for recursion contains spaces in the file name, which is treated as two files

Workaround: Modify the delimited IFS

#! /bin/bash

function Dfs
{
	old_ifs=${ifs}
	ifs=$ (echo-e ' \ n ') for
	file in ' ls-a ' $ "' Do
		if [-D $1/${file}]; Then
			dfs "$1/${file}"
		else
			echo "$1/${file}"
		fi
	do	
	ifs=${old_ifs}
}

As a good habit, changed things to change back after use

I wrote it myself. A DFS recursive traversal, the effect and the-R almost
