Powershell copy script with condition check -

our requirement copy files source destination folder.

the clause during first run of script should copied in subsequent runs should copy files have not been copied till yet , new ones.

the issue destination folder have script works on files , remove them once executed. dont want duplicate files source copied destination.

example

source-> abc.txt,def.xt 

after 1strun

dest->abc.txt,def.txt 

subsequent runs

source->abc.txt,def.xt, ghi.txt  dest->abc.txt,def.xt, ghi.txt 

now when script has worked on dest folder , removed abc.txt , ghi.txt logic should be

source->abc.txt,def.xt, ghi.txt,jkl.txt 

now when script runs should copy new files

dest->ghi.txt, jkl.txt 

i thinking if can log output after script run first time txt file , put condition check in log file if text file there before copying source folder destination .

hope able explain.

thx

you copy files not in history this:

$sourcefolder = "..." $destfolder   = "..." $historyfile  = "history.txt"  $recurse = $false  $history = get-content $historyfile  get-childitem $sourcefolder -recurse:$recurse | ? {   -not $_.psiscontainer -and $history -notcontains $_.fullname } | % {   copy-item $_.fullname $destfolder   $_.fullname >> $historyfile } 

the line $_.fullname >> $historyfile appends copied files history file.
