Mona ke mohlala oa thuso bakeng sa taelo ea Get-Evenlog

PowerShell bakeng sa ba qalang

Haeba liparamente li kentsoe ka masakaneng a lisekoere [], ke tsa boikhethelo.
Ke hore, mohlaleng ona, lebitso la koranta ka boeona le tlamehile, le lebitso la parameter Che. Haeba mofuta oa parameter le lebitso la eona li kentsoe ka masakaneng hammoho, joale parameter ke ea boikhethelo.

Haeba u sheba parameter ea EntryType, u ka bona litekanyetso tse kentsoeng ka har'a li-curly braces. Bakeng sa paramethara ena, re ka sebelisa feela boleng bo boletsoeng esale pele ho li-curly braces.

Re ka bona tlhahisoleseling mabapi le hore na paramente e ea hlokahala tlhalosong e ka tlase lebaleng le Hlokehang. Mohlaleng o ka holimo, tšobotsi ea After ke ea boikhethelo hobane Ho Hlokahala e setetsoe ho fosahetse. Ka mor'a moo re bona sebaka sa Position se shebaneng le se reng E rehiloe. Sena se bolela hore parameter e ka fumanoa feela ka lebitso, ke hore:

Get-EventLog -LogName Application -After 2020.04.26

Kaha parameter ea LogName e ne e e-na le nomoro ea 0 e boletsoeng ho e-na le Lebitso, sena se bolela hore re ka fumana parameter ntle le lebitso, empa ka ho e hlalosa ka tatellano e hlokahalang:

Get-EventLog Application -After 2020.04.26

Ha re nke taelo ena:

Get-EventLog -Newest 5 Application

Alias

E le hore re ka sebelisa litaelo tse tloaelehileng tse tsoang ho console, PowerShell e na le li-alias (Alias).

Mohlala oa lebitso la taelo ea Set-Location ke cd.

Ke hore, sebakeng sa ho bitsa taelo

Set-Location “D:”

re ka sebelisa

cd “D:”

History

Ho sheba nalane ea mehala ea litaelo, o ka sebelisa Get-History

Etsa taelo ho tloha historing Invoke-History 1; Invoke-Histori 2

Hlakola nalane ea nalane e hlakileng

Pipe

Phaephe e ho powershell ke ha sephetho sa tšebetso ea pele se fetisetsoa ho ea bobeli. Mona ke mohlala oa ho sebelisa pipeline:

Get-Verb | Measure-Object

Empa ho utloisisa phaephe hantle, a re nke mohlala o bonolo haholoanyane. Ho na le sehlopha

Get-Verb "get"

Haeba re bitsa thuso ea Get-Help Get-Verb -Full, re tla bona hore paramethara ea Leetsi e amohela tlhahiso ea pipline mme ByValue e ngotsoe ka masakaneng.

PowerShell bakeng sa ba qalang

Sena se bolela hore re ka ngola hape Get-Verb "fumana" ho "fumana" | Fumana-Leetsi.
Ke hore, sephetho sa polelo ea pele ke khoele 'me e fetisetsoa ho Leetsi paramethareng ea Get-Verb taelo ka pipline input ka boleng.
Hape ho kenya pipline e ka ba ByPropertyName. Tabeng ena, re tla fetisa ntho e nang le thepa e nang le lebitso le tšoanang Leetsi.

Mefuta-futa

Liphetoho ha lia ngoloa ka matla 'me li hlalositsoe ka letšoao la $ ka pele

$example = 4

Letšoao la > le bolela ho kenya data
Ka mohlala, $mohlala > File.txt
Ka polelo ena re tla beha data ho tsoa ho $mohlala e fapaneng ho ea faeleng
Hoa tšoana le Set-Content -Boleng $mohlala -Path File.txt

tse fapaneng

Array initialization:

$ArrayExample = @(“First”, “Second”)

Ho qala lethathamo le se nang letho:

$ArrayExample = @()

Ho fumana boleng ka index:

$ArrayExample[0]

Fumana lethathamo lohle:

$ArrayExample

Ho eketsa element:

$ArrayExample += “Third”

$ArrayExample += @(“Fourth”, “Fifth”)

Ho hlophisa:

$ArrayExample | Sort

$ArrayExample | Sort -Descending

Empa sehlopha ka boeona ha se fetohe nakong ea ho hlophisoa hona. 'Me haeba re batla hore sehlopha se be le data e hlophisitsoeng, joale re hloka ho fana ka litekanyetso tse hlophisitsoeng:

$ArrayExample = $ArrayExample | Sort

Ha ho na mokhoa oa 'nete oa ho tlosa ntho ho tsoa ho PowerShell, empa u ka e etsa ka tsela ena:

$ArrayExample = $ArrayExample | where { $_ -ne “First” }

$ArrayExample = $ArrayExample | where { $_ -ne $ArrayExample[0] }

Ho tlosa sehlopha:

$ArrayExample = $null

Loops

Loop syntax:

for($i = 0; $i -lt 5; $i++){}


$i = 0
while($i -lt 5){}


$i = 0
do{} while($i -lt 5)


$i = 0
do{} until($i -lt 5)


ForEach($item in $items){}

Tsoa ho loop ea khefu.

Ho tlohela elemente e tsoelang pele.

Lipolelo tsa maemo

if () {} elseif () {} else

switch($someIntValue){
  1 { “Option 1” }
  2 { “Option 2” }
  default { “Not set” }
}

mosebetsi

Tlhaloso ea Mosebetsi:

function Example () {
  echo &args
}

Mosebetsi oa ho sebetsa:

Example “First argument” “Second argument”

Ho hlalosa mabaka a tshebetso:

function Example () {
  param($first, $second)
}


function Example ($first, $second) {}

Mosebetsi oa ho sebetsa:

Example -first “First argument” -second “Second argument”
