Quali cose essenziali (funzioni, alias, script di avvio) hai nel tuo profilo?
Risposte:
Spesso mi trovo ad aver bisogno di alcuni aggregati di base per contare / sommare alcune cose., Ho definito queste funzioni e le uso spesso, funzionano davvero bene alla fine di una pipeline:
#
# useful agregate
#
function count
{
BEGIN { $x = 0 }
PROCESS { $x += 1 }
END { $x }
}
function product
{
BEGIN { $x = 1 }
PROCESS { $x *= $_ }
END { $x }
}
function sum
{
BEGIN { $x = 0 }
PROCESS { $x += $_ }
END { $x }
}
function average
{
BEGIN { $max = 0; $curr = 0 }
PROCESS { $max += $_; $curr += 1 }
END { $max / $curr }
}
Per essere in grado di ottenere tempo e percorso con i colori nel mio prompt:
function Get-Time { return $(get-date | foreach { $_.ToLongTimeString() } ) }
function prompt
{
# Write the time
write-host "[" -noNewLine
write-host $(Get-Time) -foreground yellow -noNewLine
write-host "] " -noNewLine
# Write the path
write-host $($(Get-Location).Path.replace($home,"~").replace("\","/")) -foreground green -noNewLine
write-host $(if ($nestedpromptlevel -ge 1) { '>>' }) -noNewLine
return "> "
}
Le seguenti funzioni sono state rubate da un blog e modificate per adattarle ai miei gusti, ma ls with colors è molto carino:
# LS.MSH
# Colorized LS function replacement
# /\/\o\/\/ 2006
# http://mow001.blogspot.com
function LL
{
param ($dir = ".", $all = $false)
$origFg = $host.ui.rawui.foregroundColor
if ( $all ) { $toList = ls -force $dir }
else { $toList = ls $dir }
foreach ($Item in $toList)
{
Switch ($Item.Extension)
{
".Exe" {$host.ui.rawui.foregroundColor = "Yellow"}
".cmd" {$host.ui.rawui.foregroundColor = "Red"}
".msh" {$host.ui.rawui.foregroundColor = "Red"}
".vbs" {$host.ui.rawui.foregroundColor = "Red"}
Default {$host.ui.rawui.foregroundColor = $origFg}
}
if ($item.Mode.StartsWith("d")) {$host.ui.rawui.foregroundColor = "Green"}
$item
}
$host.ui.rawui.foregroundColor = $origFg
}
function lla
{
param ( $dir=".")
ll $dir $true
}
function la { ls -force }
E alcune scorciatoie per evitare attività di filtraggio davvero ripetitive:
# behave like a grep command
# but work on objects, used
# to be still be allowed to use grep
filter match( $reg )
{
if ($_.tostring() -match $reg)
{ $_ }
}
# behave like a grep -v command
# but work on objects
filter exclude( $reg )
{
if (-not ($_.tostring() -match $reg))
{ $_ }
}
# behave like match but use only -like
filter like( $glob )
{
if ($_.toString() -like $glob)
{ $_ }
}
filter unlike( $glob )
{
if (-not ($_.tostring() -like $glob))
{ $_ }
}
Per configurare il mio ambiente di compilazione Visual Studio da PowerShell ho preso il VsVars32 da qui . e usalo tutto il tempo.
################################################ #############################
# Espone le variabili di ambiente in un batch e le imposta in questa sessione PS
################################################ #############################
funzione Get-Batchfile ($ file)
{
$ theCmd = "` "$ file`" & imposta "
cmd / c $ theCmd | Foreach-Object {
$ thePath, $ theValue = $ _. split ('=')
Set-Item -path env: $ thePath -value $ theValue
}
}
################################################ #############################
# Imposta le variabili VS per questa sessione PS da utilizzare
################################################ #############################
funzione VsVars32 ($ version = "9.0")
{
$ theKey = "HKLM: SOFTWARE \ Microsoft \ VisualStudio \" + $ versione
$ theVsKey = get-ItemProperty $ theKey
$ theVsInstallPath = [System.IO.Path] :: GetDirectoryName ($ theVsKey.InstallDir)
$ theVsToolsDir = [System.IO.Path] :: GetDirectoryName ($ theVsInstallPath)
$ theVsToolsDir = [System.IO.Path] :: Combine ($ theVsToolsDir, "Strumenti")
$ theBatchFile = [System.IO.Path] :: Combine ($ theVsToolsDir, "vsvars32.bat")
Get-Batchfile $ theBatchFile
[System.Console] :: Title = "Visual Studio" + $ version + "Windows Powershell"
}
Questo itera attraverso uno script PSDrive e dot-sources tutto ciò che inizia con "lib-".

}
trascrizione iniziale . Questo scriverà l'intera sessione in un file di testo. Ottimo per addestrare i nuovi assunti su come utilizzare Powershell nell'ambiente.
Il mio prompt contiene:
$width = ($Host.UI.RawUI.WindowSize.Width - 2 - $(Get-Location).ToString().Length)
$hr = New-Object System.String @('-',$width)
Write-Host -ForegroundColor Red $(Get-Location) $hr
Il che mi dà un divisore tra i comandi che è facile da vedere quando si scorre indietro. Mi mostra anche la directory corrente senza utilizzare lo spazio orizzontale sulla riga su cui sto digitando.

# Restarts explorer as the user in $UserName
function New-Explorer

Qualche filtro? Credo di si...

filter FileSizeAbove($size){if($_.Length -ge $size){$_}}
Ne ho anche alcuni che non posso ancora pubblicare, perché non sono stati completati, ma sono fondamentalmente un modo per mantenere le credenziali tra le sessioni senza scriverle come file crittografati.

aggiungo questa funzione in modo da poter vedere facilmente l'utilizzo del disco:

($objItem.Size / 1GB).ToString("f3") ($objItem.FreeSpace / 1GB).ToString("f3")
}
}

Conservo un po 'di tutto. Principalmente, il mio profilo imposta tutto l'ambiente (inclusa la chiamata di script per configurare il mio ambiente di sviluppo .NET / VS e Java).
Ridefinisco anche la prompt()funzione con il mio stile ( vedo in azione ), impostato diversi alias per altri script e comandi. e cambia ciò che $HOMEpunta a.

Ne trarrai beneficio se hai mai cercato uno stupido errore di battitura, ad es. output di $ varsometext invece di $ var sometext

Utile per lavorare con xml, come l'output dei comandi svn con --xml.

Questo aggiungerà gli snap-in che hai installato nella sessione di PowerShell. Il motivo per cui potresti voler fare qualcosa del genere è che è facile da mantenere e funziona bene se sincronizzi il tuo profilo su più sistemi. Se uno snap-in non è installato, non vedrai un messaggio di errore.

Se usi Git per clonare il mio repository nella tua cartella Documenti (o qualunque cartella sia sopra "WindowsPowerShell" nella tua variabile $ PROFILE), otterrai tutta la mia bontà.
Il main profile.ps1imposta la sottocartella con il nome Addonscome a PSDrive, quindi trova tutti i file .ps1 sotto quella cartella da caricare.
Mi piace abbastanza il gocomando, che memorizza un dizionario di posizioni stenografiche da visitare facilmente. Ad esempio, go vspmi porterà a C:\Visual Studio 2008\Projects.
Mi piace anche sovrascrivere il Set-Locationcmdlet per eseguire sia Set-LocationeGet-ChildItem .
L'altro mio preferito è essere in grado di fare una mkdircosa Set-Location xyzdopo la corsa New-Item xyz -Type Directory.

Tengo vuoto il mio profilo. Invece, ho cartelle di script che posso navigare per caricare funzionalità e alias nella sessione. Una cartella sarà modulare, con librerie di funzioni e assiemi. Per il lavoro ad hoc, avrò uno script per caricare alias e funzioni. Se voglio eseguire il munge dei registri degli eventi, navigherei in una cartella scripts \ eventlogs ed eseguirò
PS > . .\DotSourceThisToLoadSomeHandyEventLogMonitoringFunctions.ps1
Lo faccio perché ho bisogno di condividere script con altri o spostarli da macchina a macchina. Mi piace poter copiare una cartella di script e assembly e farlo funzionare su qualsiasi macchina per qualsiasi utente.
Ma vuoi una divertente collezione di trucchi. Ecco uno script da cui dipendono molti dei miei "profili". Consente chiamate a servizi Web che utilizzano SSL autofirmato per l'esplorazione ad hoc dei servizi Web in fase di sviluppo. Sì, mischio liberamente C # nei miei script PowerShell.
# Using a target web service that requires SSL, but server is self-signed.
# Without this, we'll fail unable to establish trust relationship.

Ottima domanda. Poiché ho a che fare con diversi host PowerShell diversi, eseguo un po 'di registrazione in ciascuno dei diversi profili, solo per rendere più chiaro il contesto di eventuali altri messaggi. In profile.ps1, attualmente ho solo quello, ma a volte lo cambio in base al contesto:
if ($PSVersionTable.PsVersion.Major -ge 3) {
Write-Host "Executing $PSCommandPath"
}
Il mio host preferito è l'ISE, in Microsoft.PowerShellIse_profile.ps1, ho:
if ($PSVersionTable.PsVersion.Major -ge 3) {
Write-Host "Executing $PSCommandPath"
}
if ( New-PSDrive -ErrorAction Ignore One FileSystem `
(Get-ItemProperty hkcu:\Software\Microsoft\SkyDrive UserFolder).UserFolder) {
Write-Host -ForegroundColor Green "PSDrive One: mapped to local OneDrive/SkyDrive folder"
}
Import-Module PSCX
$PSCX:TextEditor = (get-command Powershell_ISE).Path
$PSDefaultParameterValues = @{
"Get-Help:ShowWindow" = $true
"Help:ShowWindow" = $true
"Out-Default:OutVariable" = "0"
}

Di tutto ciò che non è già elencato, Start-Steroids deve essere il mio preferito, tranne forse Start-Transcript.
