keep files from first of the month for a year

we have series of folders subfolders have logfiles in them. each folder has new log files generated daily. on occasion, log file not generated day or few days.

i want keep log file in each folder first of each month, or close day possible year , delete files older year. want delete files in folder not first of month.

so, on august 30, 2014 folder 1 may have log files each day in august except august 1. when run script on september 1, want folder have files:

august 02, 2014.log

july 01, 2014.log

june 01, 2014.log

if first log file august 5th, want keep 1 , delete rest.

i have 30+ folders daily log files. takes long time go each folder, see log closest beginning of month, delete remaining files month, find log files on year ago , delete one.

ive tried few iterations but, keep getting stuck. appreciated.

thanks!

steve

im not sure how convert $testdate date , not time.

can use $testdate.date date portion only:

ps c:\scripts\powershell scripts\misc testing\9-3-2014> $testdate.date  saturday, may 31, 2014 12:00:00 am
