shell脚本遍历当前目录下以数字命名的目录，并打印

#!/bin/bash

single=''　　#定义以个位数为目录的集合
double=''　　#定位十位数为目录的集合
#按照需要可以根据实际情况再定义以百位数为目录的集合

for dir in `ls -d [0-9]*`    #开始遍历
do
   if [ `ls -d [0-9]* | wc -l` -ge 10 ];then　　#判断当前的目录总数是否大于等于10
      if [ `echo $dir | wc -c` = 2 ];then　　#判断是否为个位数的目录
            single="${single} $dir"　　#加入到集合中
      else
            double="${double} $dir"　　#加入到集合中
      fi
   fi

done

for dirname in ${single}
do
   echo "#TODO $dirname"
done
for dirname in ${double}
do
   echo "#TODO $dirname"
done

#echo ${single}
#echo ${double}

遍历目录，并删除掉一些目录的方法

#!/bin/bash

root_path="/opt/path"
for dir in `ls ./`
do
        cd "${root_path}/${dir}"
        echo "${dir}==dir"
        for subdir in `ls ./`
        do
                cd "${root_path}/${dir}/${subdir}"
                echo "${subdir}==sub dir."
                for ssdir in `ls -t | awk 'NR>40{print $1}'`
                do
                        echo "ssdir==${ssdir}"
                        echo "abs path=${root_path}/${dir}/${subdir}/${ssdir}/"
                        rm -rf ${root_path}/${dir}/${subdir}/${ssdir}
                        ls ${root_path}/${dir}/${subdir}/${ssdir}
                done
        done

done

change(){
    rep=$1
    posts=`get_port`
    port=`echo ${posts} | awk -F , '{print $2}'`
    ja="ja_co_co=" -javaagent:${JACOCOAGENT}=includes=*,output=tcpserver,port=${port},address=*,append=true""
    if [ -f "${ss}"  ];then
       echo "${rep} === ${posts}"
