Assuming you mean change the Date.txt file after this script has created it, there are a few ways you can get that information changed:
#set up the header (doesn't need to be done if the header is in the file)$header="user name", "ID", "Full name", "Home Director"# import your file (called del.txt here)$file=Import-Csv-Delimiter":" .\del.txt-Header$header#from there you can do loads of stuff with it
# convert to pipe delimited without double quotes$file | ConvertTo-Csv-Delimiter"|" | % {$_.Replace('"','')}
#export to pipe delimtied $file | Export-Csv-Delimiter"|"out_del.txt# format as a table on screen$file | Format-Table
