Linux编程实现递归查找文件

命令格式如下：
SCRIPT_NAME       SEARCH_ON_DIR       SEARCH_FILENAME

#!/bin/bash
Find(){
    echo $3" "$1
    files=`ls $1`
    for file in $files
    do
        if [ -d $1"/"$file ]
        then
            Find $1"/"$file $2 `expr $3 + 1`
        elif [ $file=$2 ]
    then
            echo $1"/"$2
        fi
    done
}
FindFile(){
    if [ -d $1 ]
    then
    Find $1 $2 0
    else
    echo "This is not a directory or does not exist"
    fi
}
echo "Start finding $2 in $1"
FindFile $1 $2

基本实现简单查找功能，编写代码时应格外注意语法格式
