How to delete lines of file without changind date?

[rodrigo.brasil]

No, this is not possible. But there is a workaroud:

• You edit the file
• Then you change the date

Now I have a problem:

1. Can I edit the file inplace?
2. If YES, I need to store the date in memory an then change it
3. If NO, I need create a new file, toch it, delete the old and rename the new one

Until now, I don't see the solution to edit it inplace.

The other option, I see the answer from this question. This is the command:

Code: Select all

type input.txt | findstr /v ERROR | findstr /v REFERENCE > output.txt

Now, how can I change the last modified date of the output.txt file to be equal to input.txt?

After this, just delete and rename the new file.

So, how can I edit a file inplace or how can I copy the last mofified date of one file to another only using cmd.exe? Is this possible?

You might use powershell within cmd.exe to change the last modified date of a file, so this might help you:

Code: Select all

@echo off
setlocal enableExtensions disableDelayedExpansion

set "sourceFile=%~f0"
set "targetFile=stest.txt"

powershell.exe -Command "$(Get-Item '%targetFile%').LastWriteTime=$(Get-Item '%sourceFile%').LastWriteTime"

goto :eof
