文件类型统计

#!/bin/bash

if [ $# -ne 1 ]
then
    echo 'please input one '
fi
path=$1
declare -A wow

while read line;
do 
    ftype=`file -b $line`
    let wow["$ftype"]++;
done< <(find $path -type f -print )

echo ============= file type ================

for ftype in "${!wow[@]}";
do
    echo $ftype : ${wow["$ftype"]}
done

 脚本可以遍历指定目录下所以文件，然后统计文件信息。
