shell遞歸遍歷目錄的方法

方法一：

#!/bin/sh

function scandir() {
    local cur_dir parent_dir workdir
    workdir=$1
    cd ${workdir}
    if [ ${workdir} = "/" ]
    then
        cur_dir=""
    else
        cur_dir=$(pwd)
    fi

    for dirlist in $(ls ${cur_dir})
    do
        if test -d ${dirlist};then
            cd ${dirlist}
            scandir ${cur_dir}/${dirlist}
            cd ..
        else
            echo ${cur_dir}/${dirlist}
        fi
    done
}

if test -d $1
then
    scandir $1
elif test -f $1
then
    echo "you input a file but not a directory,pls reinput and try again"
    exit 1
else
    echo "the Directory isn't exist which you input,pls input a new one!!"
    exit 1
fi

方法二、

#! /bin/bash
function read_dir(){
    for file in `ls $1`
    do
        if [ -d $1"/"$file ]  //注意此處之間一定要加上空格，否則會報錯
        then
            read_dir $1"/"$file
        else
            echo $1"/"$file
        fi
    done
}
#測試目錄 test
read_dir test

其實這兩種方法的本質都是一樣的，只是第一個寫的多一些。
