一个for循环实现一个目录下的文件和目录遍历，很实用
[root@localhost shell_order]# cat test27.sh
#!/bin/bash
#print the directory and file
for file in /home/hustyangju/*
do
if [ -d "$file" ]
then
echo "$file is directory"
elif [ -f "$file" ]
then
echo "$file is file"
fi
done
[root@localhost shell_order]# ./test27.sh
/home/hustyangju/array is directory
/home/hustyangju/menuwindow-7.12 is directory
/home/hustyangju/menuwindow-build-desktop is directory
/home/hustyangju/shell_order is directory
[root@localhost shell_order]#
递归遍历
#! /bin/bash
read_dir(){
for file in `ls $1` #注意此处这是两个反引号，表示运行系统命令
do
if [ -d $1"/"$file ] #注意此处之间一定要加上空格，否则会报错
then
read_dir $1"/"$file
else
echo $1"/"$file #在此处处理文件即可
fi
done
}
#读取第一个参数
read_dir $1
