Update script using Regex commands - regex

Question

Created the following PS script to pull data from some reports and dump extracted data into a .csv file:
$csvContents = #()
$hashTable = #{}
$count = 0
Get-ChildItem $PSRoot\NU_*.txt | %{
Get-Content $_ |
?{$_ -imatch 'Percent of memory in use' -or $_ -imatch 'Remaining Space' -or $_ -imatch 'Percent of CPU in use' -or $_ -imatch 'Node Number' `
-or $_ -imatch 'Generated' -or $_ -imatch 'Client Name' -or $_ -imatch 'Windows Ver:' -or $_ -imatch 'ActiveName' -or $_ -imatch 'node \d+'} | %{
If($_ -imatch 'ActiveName'){
$name = (([regex]::Matches($_,'\w+') | select value).value )
$store = ([regex]::Matches($name[2],'\b\d+') | select value).value
}
If($_ -imatch 'Node Number'){
$NodeNumber = ([regex]::Matches($_,'\b\d+') | select value).value
}
If($_ -imatch 'memory in use'){
$memory = ([regex]::Matches($_,'\b\d+') | select value).value
}
If($_ -imatch 'Remaining Space'){
$space = ([regex]::Matches($_,'\b\d+') | select value).value
}
If($_ -imatch 'CPU in use'){
$cpu = ([regex]::Matches($_,'\b\d+') | select value).value
}
If($_ -imatch 'Generated'){
$Date = ([regex]::Matches($_,'(\d+)-(\d+)-(\d+) (\d+):(\d+):(?:\d+)') | select value).value #[0..2] -join '-'
}
If($_ -imatch 'Client Name'){
$ClientName = (([regex]::Matches($_,'\s+(\s+\w+)') | select value).value -join ',').trim()
}
If($_ -imatch 'Windows Ver:'){
$WinVer = ([regex]::Matches($_,'Windows Ver: (\d+)\.(\d+)') | select value).value -join ','
}
$obj = [PSCustomObject]#{
STORE = $store
DATE = $Date
NODENUMBER = $NodeNumber
POSTYPE = $ClientName
MEMORYUSAGE = $memory
FREEHDSPACE = $space
CPUUSAGE = $cpu
WINDOWSVERSION = $WinVer
}
If($_ -imatch 'Node \d+'){
$hashTable.Add($count,$obj)
$count++
}
}
}
$hashTable.values.GetEnumerator() | Sort-Object -Property DATE | ConvertTo-Csv -NoTypeInformation | Set-Content -path "$Reports\$($Store)_$(Get-Date -f yyyy-MM-dd)_$((Get-Date).tostring("hh-mm-ss")).csv" -force
Example of .csv file:
In the POSTYPE column the PCSERVER is showing 0 and I would like it to show 123. The EPC4 is showing 0 and I would like it to show 155. Any suggestions on how I can do this.

Answer 1

If you want to overwrite your source data and always use the numbers you mention, you can just add another couple of If statements before creating your $obj:
If($ClientName -eq 'PCSERVER'){
$NodeNumber = 123
}
If($ClientName -eq 'EPC4'){
$NodeNumber = 155
}
