如何在批处理脚本的文件名中插入日期和时间? [英] How to insert date and time to a filename in a batch script?

问题描述

我为Jenkins作业编写了一个批处理脚本，该脚本编译了一个".net"代码，其中一个步骤是在提取新的已编译代码之前备份当前目录.

I wrote a batch script for a Jenkins jobs which compiles a ".net" code and one of the steps there is to back up the current directory before extracting the new compiled code.

我正在使用以下几行来提取要插入备份文件名的日期和时间:

I'm using the these lines to extract the date and time which I want to insert into the backup file name:

for /F "tokens=2-4 delims=/ " %%i in ('date /t') do set date=%%k%%i%%j
for /f "tokens=1-2 delims=/:" %%a in ('time /t') do set time=%%a%%b
powershell.exe -nologo -noprofile -command "& { Add-Type -A System.IO.Compression.FileSystem; [IO.Compression.ZipFile]::CreateFromDirectory('bin', 'bin-%date%_%time%.zip'); }"
xcopy bin-%date%_%time%.zip c:\temp

问题出在time /t的输出中，它看起来像这样:

The problem is with the output of time /t which looks like that:

01:00 AM

这会导致文件名是:

bin-20170412-0100 AM.zip

这是个问题.

我想从时间变量中忽略"AM"，怎么办?

I want to omit the " AM" from the time variable, how can it be done?

推荐答案

由于您显然对powershell的使用没有问题，因此请用以下两行代替:

Because you obviously have no issue with powershell usage, replace those first two lines with:

For /F %%A In ('Powershell -C "Get-Date -Format yyyyMMdd_HHmm"'
) Do Set "archive=bin-%%A.zip"

然后，在变量%archive%中设置完整的存档文件名，以便在以下命令中使用.

You then have your full archive file name set in the variable %archive% for use in your following commands.
