假设你要执行一些数据，例如根据经销商做统计，但是数组有很多个，你懒得一个个执行，那么应该怎么办？
某某经销商->L0814 L2592 L0819 L4786

shell的for循环基础语法

#常规遍历
for i in 1 2 3 4 5   
  do    
    echo "$i-->$(uptime)"  
  done    

#批量解压缩当前文件夹下所有的.tar.gz 文件
for i in `ls ./*.tar.gz`   
   do    
     tar -zxvf $i >/dev/null  
   done  

#求1~100 的和
sum=0  
for (( i=1; i<=100; i++ ))  
  do    
   sum=$(( $sum + $i ))  
  done    
echo "1+2+3+...+100=$sum"  

如何循环遍历并动态注入参数？

当然是写成shell脚本去动态遍历，通过shell自动切割string数组(这个也是相当智能，好用的)，然后注入动态参数${k}达到遍历执行的效果。注意变量赋值的时候,=两边绝对不能有空格

以下脚本选自公司大数据平台，进行一些删减，请注意动态注入参数${k}的地方

dealListString=("  L0814  L2592  L0819 L4786 ")

for k in $dealListString
do 
echo '导入'${k}'开始'

left join (select txn.member_id,txn.row_id,txn.created,txn.source_cd,prod.alias_name from (select member_id,row_id,created,source_cd,prod_id,x_store_id from ori_siebel_s_loy_txn where bu_id ='1-1JK1' and TYPE_CD = '应计' and Status_Cd = '已处理' and sub_status_cd = '成功' ) txn
