导读：#!/bin/bashecho SCRIPT: $0echo "Enter Customer Order Ref (e.g. 100018)"read P_CUST_ORDER_REFecho "Enter DU Id (e.g. 100018)"read P_DU_IDP_ORDER_ID=${P_CUST_ORDER_REF}${P_DU_ID}#Loop through all XML files in the current directoryfor f in *.

#!/bin/bash

echo SCRIPT: $0
echo "Enter Customer Order Ref (e.g. 100018)"
read P_CUST_ORDER_REF
echo "Enter DU Id (e.g. 100018)"
read P_DU_ID

P_ORDER_ID=${P_CUST_ORDER_REF}${P_DU_ID}


#Loop through all XML files in the current directory
for f in *.xml
do
  #Increment P_CUST_ORDER_REF here
done

在for循环中,如何在每次循环时将P_CUST_ORDER_REF递增1

so it READs 10000028 uses it on first loop
2nd 10000029
3rd 10000030
4th 10000031

解决方法

((P_CUST_ORDER_REF+=1))

要么

let P_CUST_ORDER_REF+=1
