if | is OR , what is the symbol for and

$date = (Get-Date).AddDays(-1).ToString(‘MM/dd/yyyy’)
[String[]]$Match = $content | select-string -Pattern “(Successful incremental backup|$date )”

This is a statement I am using in my script. So it gives me all the matches which has yesterdays date in any statmeent. Now , I want a result which has a statement containing yesterdays date along with “successful incremental backup”

This is what I want to search :

02/19/2017 00:49:21 Successful incremental backup of ‘\bentpsystpc02\d$’

So , if | stands for OR , how can I represent AND ???

The -Pattern parameter is accepting a regular expression; the pipe isn’t an “OR” operator, it’s an alternative set operator, which is a bit different. There’s no AND operator per se in regular expression syntax.

Thanks Don !!!..you have been a great help :slight_smile:
