Powershell – Windows command prompt: how to get the output of a command into a environment variable

batchpowershellwindows-command-prompt

I want to have an environment variable that contains the day of week in cmd.exe.

When I run this command I get the result I want.

C:\Users\tisc> powershell (get-date).dayofweek
Friday

Here I'm trying to store the result in an environment variable.

C:\Users\tisc> set dow = powershell (get-date).dayofweek

But when I try to get it I don't get the string as I wanted.

C:\Users\tisc> set dow
DoW=0
dow = powershell (get-date).dayofweek

My goal is to use the variable in a batch file for some backup scripts.

You can use something like:

$env:DOW = "foo"

Windows – Quickest way to scheduled file deletion on Windows

Instead of worrying about the age of the files, first delete old backups until there are only 7 daily backups remaining and then worry about deleting the oldest file in the directory before we do each new backup.

Deleting the oldest file in a directory is pretty easy to do in batch script:

SET BACKUPDIR=C:\PATH\TO\BACKUPS
FOR /F %%i IN ('DIR /B /O-D %BACKUPDIR%') DO SET OLDEST=%%i
DEL %BACKUPDIR%\%OLDEST%

The only real trick is the command DIR /B /O-D which lists plain file names sorted by date, oldest last. We use the FOR loop to capture each file name in the OLDEST variable so when the loop is done %OLDEST% will expand to the name of the oldest file.
