LVL Shell Script 分享

寫shell script必須要先了解LVL的語法內容才有辦法，知道應該要如何來達到我們要的效果，所以必須先看上一篇LVL command file 範例。

廢話不多說，以下先分享shell script範例，再做解說。

LVL Shell Script Example.

#! /bin/bash

##script name: genLVL.sh

##description:

##    This script is used to make LVL rule file.

##Author: ron.huang

##History:

##    2021/06/22 ron.huang release

##usage:

##    1.Please modify the layer map to the following format first.

##    2.Modify customized region

##    3.Run script ex.    ./genLVL.sh

##customized region

LAYERMAP=layermap

LVLFILE=lvl.cal

## Do not modify below

getLayerNames=$(cat $LAYERMAP | awk '{print $1}');

getPurpuseNames=$(cat $LAYERMAP | awk '{print $2}');

getLayerNumbers=$(cat $LAYERMAP | awk '{print $3}');

getDatatypeNumbers=$(cat $LAYERMAP | awk '{print $4}');
