想将一个文件按照配置文件内容进行命名。先选择了Linux shell，最后发现KEIL调用的命令行没有办法识别wsl，兼容性还是不太行。

#ifndef _SYSTEM_CONFIG_H_
#define _SYSTEM_CONFIG_H_


#define DEVICE_SW           1  // 软件版本
#define DEVICE_HW           1  // 硬件版本
#define DEVICE_TYPE         2  // 设备类型，1：网关 2：终端


#endif

generate_sw.sh

#!/bin/bash

path="../"
fwSrcName="Nordic_52840_firmware.bin"
baseName="Nordic_52840_firmware_sw"
configFile="../../config/system_config.h"
config1="DEVICE_SW"
config2="DEVICE_HW"
config3="DEVICE_TYPE"

softwareID=$(cat $configFile | grep $config1 | tr '\r' ' ' |  awk -F " " '{print $3}')
hardwareID=$(cat $configFile | grep $config2 | tr '\r' ' ' |  awk -F " " '{print $3}')
deviceType=$(cat $configFile | grep $config3 | tr '\r' ' ' |  awk -F " " '{print $3}')
currentTime=$(date +"%Y%m%d_%H%M")
fullName=$baseName$softwareID"_hw"$hardwareID"_dt"$deviceType"_"$currentTime".bin"
echo $fullName
mv $path$fwSrcName $path$fullName

modify_fw_name.bat

wsl ../script/generate_sw.sh
pause

直接双击是可以运行的。但是在KEIL中调用，会不识别wsl。

最后改用Python，一下就搞定了。Python，牛逼。

# coding:utf-8
import os
import re
import time

f1 = open('../../config/system_config.h', 'r')

data1 = f1.readlines()

f1.close()

data1_len = len(data1)

# print(data1_len)

# print(data1)

config1 = 'DEVICE_SW'
config2 = 'DEVICE_HW'
config3 = 'DEVICE_TYPE'

baseName = "Nordic_52840_firmware_sw"
configFile="../../config/system_config.h"

path = "../"
binFile1_name = "Nordic_52840_firmware.bin"

currentDate = time.strftime("%Y%m%d_%H%M", time.localtime())
#print(currentDate)

for line_data in data1:
    t = line_data.find(config1)
    if t != -1:
        device_sw = re.findall(r"\d+\.?\d*", line_data[t:])
        #print(int(device_sw[0]))

    t = line_data.find(config2)
    if t != -1:
        device_hw = re.findall(r"\d+\.?\d*", line_data[t:])
        #print(int(device_hw[0]))
    
    t = line_data.find(config3)
    if t != -1:
        device_type = re.findall(r"\d+\.?\d*", line_data[t:])
        #print(int(device_type[0]))


fullName = baseName + device_sw[0] + "_hw" + device_hw[0] + "_dt" + device_type[0] + "_" + currentDate + ".bin"

#print(fullName)

binFile1 = path + binFile1_name
binFile2 = path + fullName
os.rename(binFile1, binFile2)

#currentPath = os.getcwd()
print("生成升级文件：" + os.path.abspath(os.path.dirname(binFile2))+ "\\" + fullName)
