History script powershell

V ukázce bude nové vylepšené start-demo powershell,verze 3.3.3,hlavně ale viz niže, script pro praci s historii,vylepšený export,import atd.

Start-demo mimochodem podporuje vylepšenou automatizaci – autoexecute mode a autospeed parametr a mnoho mnoho dalšího.Je to předělavka původního Jeffrey Snover's original Start-Demo script od Joel "Jaykul" Bennetta.

Jak pracuje start demo a jak si tam vkladat svoje sekvence je popsáno jak na strankach poshcode kde je upravené start-demo ke stažení tak někde,bůhvíkde o hodně přispěvků zpět na tomto blogu.

Na konci videa je ještě ukazka prace s profilem powershellu– jeho uprava ,vlastní alias,vložení funkce,volání funkce.

Slibovaný script pro práci s historií,význam má alespon pro mne je to tak ,pokud je v profilu.Autora a popis si vyhledejte – bude bud na pashcode nebo technet scriptcentru,změnil jsem nazev funkce a maxcount,takže kdo chce původní hodnoty může se po něm mrknout,vzhledem k tomu že ho mam v profilu původní popis scriptu už nemám.Nicmeně vychazet by se mělo z http://www.nivot.org/2009/08/15/PowerShell20PersistingCommandHistory.aspx
