Kana iwe ukatarisa iyo EntryType parameter, unogona kuona kukosha kwakavharirwa mumabhuraketi akamonana. Kune iyi parameter, isu tinogona chete kushandisa zvakafanotsanangurwa kukosha muma curly braces.

Ruzivo rwekuti kana parameter ichidikanwa inogona kuoneka mune tsananguro iri pazasi mundima Inodiwa. Mumuenzaniso uri pamusoro, iyo After hunhu ndeye sarudzo nekuti Inodiwa yakaiswa kuti inhema. Tevere, tinoona nzvimbo yePosition yakatarisana iyo inoti Yakatumidzwa. Izvi zvinoreva kuti iwe unogona kureva parameter chete nezita, kureva:

Get-EventLog -LogName Application -After 2020.04.26

Ndiko kuti pachinzvimbo chekudaidza murairo

Set-Location “D:”

tinogona kushandisa

cd “D:”

History

Kuti uone nhoroondo yekuraira mafoni, unogona kushandisa Get-History

Ita murairo kubva munhoroondo Invoke-History 1; Invoke History 2

Zvakajeka-Nhoroondo

Pipeline

Pombi mupowershell ndipo apo mhedzisiro yebasa rekutanga inopfuudzwa kune yechipiri. Heino muenzaniso uchishandisa pipeline:

Get-Verb | Measure-Object

Zvinyorwa

Zvinosiyana-siyana hazvina kunyorwa zvakasimba uye zvinotsanangurwa ne $ kumberi

$example = 4

Chiratidzo > zvinoreva kuisa data mukati
Semuenzaniso, $muenzaniso > File.txt
Nekutaura uku, isu tichaisa iyo data kubva ku $example inoshanduka kuita faira
Same as Set-Content -Value $example -Path File.txt

Arrays

Array kutanga:

$ArrayExample = @(“First”, “Second”)

Empty array kutanga:

$ArrayExample = @()

Kuwana kukosha nendekisi:

$ArrayExample[0]

Tora hurongwa hwese:

$ArrayExample

Kuwedzera chinhu:

$ArrayExample += “Third”

$ArrayExample += @(“Fourth”, “Fifth”)

Kuronga:

$ArrayExample | Sort

$ArrayExample | Sort -Descending

Asi iyo array pachayo inoramba isina kuchinjika nekurongedza uku. Uye kana tichida kuti hurongwa huve hwakarongeka data, saka tinoda kugovera maitiro akarongwa:

$ArrayExample = $ArrayExample | Sort

Iko hakuna nzira yekubvisa chinhu kubva pane array muPowerShell, asi iwe unogona kuzviita seizvi:

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

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

Kubvisa array:

$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){}

Buda kubva pabreak loop.

Svetuka chinhu chekuenderera mberi.

Mamiriro Ekutaura

if () {} elseif () {} else

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

basa

Tsanangudzo yebasa

function Example () {
  echo &args
}

Basa rekutanga:

Example “First argument” “Second argument”

Kutsanangudza nharo mukuita:

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

function Example ($first, $second) {}
