Read or parse a numberset within a filename

PowerShell Help
1

I’m using PowerShell to check that certain files are present in a folder location. If they are all present then the script will just state that 0 files are missing and if there are missing files it will tell you which ones are missing.

The files that I’m checking have a date at the end of the filename. I need my script to ignore that part of the filename or read the date part and so long as the rest of the filename is present return no errors.

Filename example: 0106-pos-20170917123002.data

The bit of the filename I’m really interested in is 0106-pos-.data.

Here is my script:

$storenum = Read-Host -Prompt "Store number (include leading zero)"
#$mbo_ip = Read-Host -Prompt "Back office IP"
$missing = 0

$sdc_pump = "\\10.xxx.xxx.xxx\gkretail\sdc\stores\device-pump"
$pos_data_file = $storenum + "-pos-"
$sdc_path = $sdc_pump + "\" + $pos_data_file

"--"
"Device Pump: config\parameter files"
if (-not $(Test-Path $sdc_path\.data)) {
    $missing++; "$sdc_path\.data not present"
}

"=="
"Store $storenum is missing $missing entries"
"=="

if (0) {
}

This is the result I get when I run the script.

Store number (include leading zero): 0106
--
Device Pump: config\parameter files
\\10.201.70.126\gkretail\sdc\stores\device-pump\0106-pos-[1-14]*.data\.data not present
==
Store 0106 is missing 1 entries
==

The reason it states that the file is missing is because it cant read the date omn the end of the filename which will always be changing.
Thanks in advance for any help.

Could you post some more examples of good data and bad data?
Based on your description i’m not fully following.

Some extra info would be nice, what are gooed and bad files.
But shit looks promising:

$pos_data_file = $storenum + "-pos-"
$sdc_path = $sdc_pump + "\" + $pos_data_file

"--"
"Device Pump: config\parameter files"
if (-not $(Test-Path "$sdc_path*.data")) {
    $missing++; "$sdc_path*.data not present"
}
"=="
"Store

I’m not sure i got the question right but here goes.
So i made a testfolder that contains:

    gci -Path C:\temp\pos\ 

    Mode                LastWriteTime         Length Name                                          
    ----                -------------         ------ ----                                          
    -a----       20-09-2017     15:36              0 0106-pos-20170917123002.data                  
    -a----       20-09-2017     15:36              0 0107-pos-20170917123002.data                  
    -a----       20-09-2017     15:36              0 0108-pos-20170917123002.data                  
    -a----       20-09-2017     15:36              0 0109-pos-20170917123002.data                  
    -a----       20-09-2017     15:36              0 0110-pos-20170917123002.data         


    $items  = gci -Path C:\temp\pos\ | Select Name -ExpandProperty Name

    $lookfor = "0111-pos-"
    $found = $null
    foreach($item in $items){
        $r = [REGEX]::Matches($item, '^(\d{4}[-]pos[-])')
    
        if($r.value -match $lookfor){
            write-host $r.value -ForegroundColor green
            $found++
        }
    }
    if($found -lt 1){
            write-host $lookfor "was not found" -ForegroundColor red
        }

$lookfor = “0111-pos-”
Would have the output: 0111-pos- was not found in a red color.

$lookfor = “0106-pos-”
Would output “0106-pos-” in a green color.

Other way to go about it :

   
    $items  = gci -Path C:\temp\pos\ | Select Name -ExpandProperty Name

    $lookfor = "0106-pos-"
    $found = $null
    foreach($item in $items){
    $r = [REGEX]::Matches($item, '^(\d{4}[-]pos[-])')
    if(($r.value -match $lookfor) -eq "true"){
        $r.value
    }
    }
    # This would only show if true. You can change that to false ofc;

Hi guys,
Thanks for the suggestions.
Here’s the script looking for a different set of files.

This is the script with the files I’m looking for, manually entered in at line 12

$storenum = Read-Host -Prompt "Store number (include leading zero)"
#$mbo_ip = Read-Host -Prompt "Back office IP"
$missing = 0

$sdc = "\\10.xxx.xxx.xxx\gkretail\sdc\stores"
$sdc_store = "STORE-SDC-" + $storenum
$sdc_path = $sdc + "\" + $sdc_store


"--"
"SDC: config\parameter files"
if (-Not $(test-path $sdc_path\config\parameter\booking.properties)) {$missing++; "$sdc_path\config\parameter\booking.properties not present"}
if (-Not $(test-path $sdc_path\config\parameter\common.properties)) {$missing++; "$sdc_path\config\parameter\common.properties not present"}
if (-Not $(test-path $sdc_path\config\parameter\device-status.properties)) {$missing++; "$sdc_path\config\parameter\device-status.properties not present"}
if (-Not $(test-path $sdc_path\config\parameter\export-to-netweaver-llp.properties)) {$missing++; "$sdc_path\config\parameter\export-to-netweaver-llp.properties not present"}
if (-Not $(test-path $sdc_path\config\parameter\export.properties)) {$missing++; "$sdc_path\config\parameter\export.properties not present"}
if (-Not $(test-path $sdc_path\config\parameter\external_locations.xml)) {$missing++; "$sdc_path\config\parameter\external_locations.xml not present"}



"=="
"Store $storenum is missing $missing entries"
"=="


if (0) {


}

This is the result when you give it a store number that has all the files listed in the script.

Store number (include leading zero): 0344
--
SDC: config\parameter files
--
SDC: sm-dc-import folders
--
==
Store 0344 is missing 0 entries
==

Here’s the result when a store is missing the files.

These are the results I expect to see
Does this make it any clearer as to what I’m trying to achieve or have is this even more confusing ?

Again, thanks for any time you guys take to have a look at my issue.

It seems like using get-childitem with a wildcard to account for the timestamp would be more effective.

$storenum = Read-Host -Prompt "Store number (include leading zero)"
$missing = 0

$sdc_pump = "\\10.xxx.xxx.xxx\gkretail\sdc\stores\device-pump"
$pos_data_file = $storenum + "-pos-"
$sdc_path = $sdc_pump + "\" + $pos_data_file

"--"
"Device Pump: config\parameter files"
if (-not (Get-ChildItem "$sdc_path*.data")) {
    $missing++
    "$sdc_path.data not present"
}

"=="
"Store $storenum is missing $missing entries"
"=="

Hi Curtis,
I’ve just tried your version of the script and it works…brilliant.
I was trying the wildcard but just could not get it right.

Many thanks Curtis, Chris and Snak3d0c for all your help on this thread.
