преобразовать вывод списка в таблицу (объект)

Question

Из iperf3 я отфильтровал следующий вывод:

& $exe -c my_host | Select-Object -Index (2..12)

[ ID] Interval           Transfer     Bandwidth
[  4]   0.00-1.00   sec  11.4 MBytes  95.4 Mbits/sec                  
[  4]   1.00-2.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   2.00-3.00   sec  11.2 MBytes  94.3 Mbits/sec                  
[  4]   3.00-4.00   sec  11.2 MBytes  94.5 Mbits/sec                  
[  4]   4.00-5.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   5.00-6.00   sec  11.2 MBytes  94.4 Mbits/sec                  
[  4]   6.00-7.00   sec  11.2 MBytes  94.4 Mbits/sec                  
[  4]   7.00-8.00   sec  11.2 MBytes  94.3 Mbits/sec                  
[  4]   8.00-9.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   9.00-10.00  sec  11.2 MBytes  94.5 Mbits/sec                             

как я могу преобразовать его в таблицу / объект в powershell для дальнейшей обработки?

Answer 1

Похоже, у вас уже есть строковый массив в качестве вывода, что приводит к таблице с фиксированной шириной.

Ниже я использую Here-String для имитации этого массива

$output = @"
[ ID] Interval           Transfer     Bandwidth
[  4]   0.00-1.00   sec  11.4 MBytes  95.4 Mbits/sec                  
[  4]   1.00-2.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   2.00-3.00   sec  11.2 MBytes  94.3 Mbits/sec                  
[  4]   3.00-4.00   sec  11.2 MBytes  94.5 Mbits/sec                  
[  4]   4.00-5.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   5.00-6.00   sec  11.2 MBytes  94.4 Mbits/sec                  
[  4]   6.00-7.00   sec  11.2 MBytes  94.4 Mbits/sec                  
[  4]   7.00-8.00   sec  11.2 MBytes  94.3 Mbits/sec                  
[  4]   8.00-9.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   9.00-10.00  sec  11.2 MBytes  94.5 Mbits/sec         
"@ -split '\r?\n'

$result = for ($i = 1; $i -lt $output.Count; $i++) {
    if ($output[$i] -match '^(?<id>.{6})(?<interval>.{19})(?<transfer>.{13})(?<bandwidth>.*)') {
        [PsCustomObject]@{
            'ID' = $matches['id'].Trim('[] ')
            'Interval' = $matches['interval'].Trim()
            'Transfer' = $matches['transfer'].Trim()
            'BandWidth' = $matches['bandwidth'].Trim()
        }
    }
}

# output on screen
$result

#output to CSV file
$result | Export-Csv -Path 'X:\table.csv' -NoTypeInformation

Результат:

ID Interval        Transfer    BandWidth     
-- --------        --------    ---------     
4  0.00-1.00   sec 11.4 MBytes 95.4 Mbits/sec
4  1.00-2.00   sec 11.2 MBytes 94.2 Mbits/sec
4  2.00-3.00   sec 11.2 MBytes 94.3 Mbits/sec
4  3.00-4.00   sec 11.2 MBytes 94.5 Mbits/sec
4  4.00-5.00   sec 11.2 MBytes 94.2 Mbits/sec
4  5.00-6.00   sec 11.2 MBytes 94.4 Mbits/sec
4  6.00-7.00   sec 11.2 MBytes 94.4 Mbits/sec
4  7.00-8.00   sec 11.2 MBytes 94.3 Mbits/sec
4  8.00-9.00   sec 11.2 MBytes 94.2 Mbits/sec
4  9.00-10.00  sec 11.2 MBytes 94.5 Mbits/sec

Answer 2

Использование этой ConvertFrom-SourceTable :

$TextTable = '
[ ID] Interval           Transfer     Bandwidth
[  4]   0.00-1.00   sec  11.4 MBytes  95.4 Mbits/sec                  
[  4]   1.00-2.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   2.00-3.00   sec  11.2 MBytes  94.3 Mbits/sec                  
[  4]   3.00-4.00   sec  11.2 MBytes  94.5 Mbits/sec                  
[  4]   4.00-5.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   5.00-6.00   sec  11.2 MBytes  94.4 Mbits/sec                  
[  4]   6.00-7.00   sec  11.2 MBytes  94.4 Mbits/sec                  
[  4]   7.00-8.00   sec  11.2 MBytes  94.3 Mbits/sec                  
[  4]   8.00-9.00   sec  11.2 MBytes  94.2 Mbits/sec                  
[  4]   9.00-10.00  sec  11.2 MBytes  94.5 Mbits/sec      
'

$TextTable | ConvertFrom-SourceTable -Literal -Omit '[]'

ID Interval        Transfer    Bandwidth
