linux shell程序，如何输入一个文件名判断它是文件夹还是文件?

#! /bin/bash

# filename:FileType.sh

read -p "Please input the filename :" filename

fpath=$filename

if [ -d $fpath ]

then

echo "谈渗枯$fpath is a direstory."

elif [ -e $fpath ]

then

echo "喊宴$fpath is a file."

else

echo "$fpath is NOT a file or direstory."

fi

Test-Path $path -PathType Container

[System.IO.Directory]::Exists($path)

# 文件存在慎裂

Test-Path $path -PathType Leaf

[system.IO.File]::Exists($path)
