Vista - -match V1 vs V2

I noticed that -match works a lot differently in V1 vs V2. i was wondering
if there was some way to get the exact match (not line) of the regex that
would work in both V1 and V2.

im guessing no, since V1 uses $matches and V2 returns the results, but i
thought i'd ask

Thanks
Justin

Hi Justin,

Can you share the code you are using?

yeah i was just thinking i should do that, sorry

i have a text file that looks like:
****************************************************************
*
* Amicas database backup started at Fri 08/28/2009 22:08:01.32 on RADAMICAS2
*
****************************************************************

.... other info....

----------------------------------------------------------------
****************************************************************
*
* Amicas database backup completed at Sat 08/29/2009 19:12:20.25
*
****************************************************************

what i really want to do is grab the date/time and then do a a datediff to
figure out how much time it took.

so i did a pattern match like so "\d+/\d+/\d+\s\d+:\d+:\d+\.\d+" which finds
it, but in V2 it just returns the lines... in V1 it returns the lines and
filles $matches with the actual match.

i'd like a way to pull out the date and time that works in both V1 and V2

Thanks
Justin

I'd recommend a switch statement to retrieve the start and end values.
The RegEx $pat will capture the date/time string, so when combined with the RegEx in the switch statement, this value will be available in the 1st group, i.e. $Matches[1]

# Requires -Version 2
$log = 'C:\Amicas.txt'
$pat = '(\p{L}{3} (\d{1,2}/){2}\d{4} (\d{1,2}\{2}\d{2}\.\d{2})'
[DateTime]$start, [DateTime]$end = switch -regex -file $log {
"^\* .+ started at $pat" {$Matches[1]}
"^\* .+ completed at $pat" {$Matches[1]}
}
$start
$end
$diff = $end - $start
$diff

# you can reduce the switch statement to one pattern

[DateTime]$start, [DateTime]$end = switch -regex -file $log {
"^\* .+ (?:started|completed) at $pat" {$Matches[1]}
}

Thanks Robert. Part of what i was trying to do was make it compatible with
V1 and V2. currently my prod servers are all V1 but with V2 on the way im
trying to write any new scripts so that they work on either version.

Thanks
Justin

Mmm since this is the year of data parsing
and charting (and yes Regex is also included)
then perhaps:

FYI

"Log Parser" - Bing
http://www.bing.com/search?q=%22Log+Parser%22

Mmm after all these years of examples
of Windows-based Log parser usage,
perhaps one is parsing the log or file with
Log Parser and storing the parsed data
as one goes along parsing the file or log

( moving data from tool to tool, is after all,
the PowerShell way )

and using this saved (file, array, etc.) parsed data
for perhaps a report for the boss?

Here PowerShell uses Log Parser:

$theDates = LogParser.exe "SELECT
EXTRACT_TOKEN(text,1,' at ')
FROM '$pwd\databaselog.log'
WHERE Text LIKE '* A%' " -i textline -q

# For later usage store the split up line.
$splitFirstLine = $theDates[0].Split(" ")

[DateTime]$start = $theDates[0].Split("on")[0]
[DateTime]$end = $theDates[1]
$start
$end
$diff = $end - $start
" "
$diff

# Perhaps make a report with a chart
# as well as text data for the boss.
$chartData = @"
Hours,Minutes,seconds
$($diff.hours),$($diff.minutes),$($diff.seconds)
"@

$chartTitle = $splitFirstLine[-1] + "`n" +
$splitFirstLine[0] + " " +
$splitFirstLine[1] + " to " +
$theDates[1].Split(" ")[0] + " " +
$theDates[1].Split(" ")[1]

$chartData | LogParser.exe "SELECT hours, minutes, seconds
into testChart.gif
FROM STDIN " -i csv -stats off -o chart `
-chartType ColumnClustered -chartTitle $ChartTitle

invoke-item testChart.gif

" "
"Done!"
" "
Exit

PowerShell 2 RTM
should make one want to include
all these exciting graphics
within one's boss's reports!

As always enjoy the automation
of tools, including graphic tools,
within the Windows-based, .NET aware,
WPF accessible, multi-processes on
the same IP / Port usage,
admin's automation tool,
powershell.exe!

actually, what im doing is pulling in all this data about different jobs
(backups mostly) and dumping it in to a DB to do trending on and i was going
to use log parser (or more likely the web graph addon that it uses) to
create web pages that will show this sort of info... increase of time and
size etc etc

Thanks!
Justin
