Just popping in

Sometimes when you play old games it is better to save daily a zipfile of the content of the full directoty as it could be possible to lost some data or objects.

On Windows I created a.bat file that uses wmic to get the timestamp (so is not dependant to locale), create an file name and run 7zip to create an archive of the game folder.

As an example:


@echo off

for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"

set "YY=%dt:~2,2%" & set "YYYY=%dt:~0,4%" & set "MM=%dt:~4,2%" & set "DD=%dt:~6,2%"

set "HH=%dt:~8,2%" & set "Min=%dt:~10,2%" & set "Sec=%dt:~12,2%"

set "datestamp=%YYYY%%MM%%DD%" & set "timestamp=%HH%%Min%%Sec%"

set filename="E:\GOGLibrary\ShardOfSpingBackup_%datestamp%_%timestamp%.zip"

set SHARDDIR="E:\GOGLibrary\Shard of Spring"

set SEVENZIP="C:\Program Files\7-Zip\7z.exe"



echo calling ... %SEVENZIP% a -r %filename% %SHARDDIR%

call %SEVENZIP% a -r %filename% %SHARDDIR%



pause

I would like to create a similar script on Amiga, but I can't find how to set a variable with a timestamp.

Any suggestion? (Thank you!)

Just can't stay away

Yep, like @NinjaCyborg says.

For an example, I do it like this in one of my scripts:

set dt `C:Date LFORMAT "%Y%m%d%H%M%S"`

PS. You can edit the LFORMAT string to your wish, e.g. putting your underscore between the %d and the %H.

Best regards,

Niels
