A "tail -f" equivalent command in Powershell to show real time logging A call to SSPI failed A connection to the directory on which to process the request was unavailable. This is likely a transient condition. A fast way to remove duplicated lines from an unsorted text file? a lot of c...
Thewherecommand is a Windowswhichequivalent in a command-line prompt (CMD). In a Windows PowerShell the alternative for thewhichcommand is theGet-Commandutility. In this note i will show how to find paths of executable commands in Windows. Cool Tip:Windowslsusbcommand equivalent in PowerShell!
Use theTee-Objectcmdlet, which sends command output to a text file and then sends it to the pipeline. Use the PowerShell redirection operators. Redirecting the output of a PowerShell command (cmdlet, function, script) using the redirection operator (>) is functionally equivalent to piping toOut...

Runs the pipeline before it in the background, in a PowerShell job. This operator acts similarly to the Unix control operator ampersand (&), which runs the command before it asynchronously in subshell as a job. This operator is functionally equivalent toStart-Job. By default, the background...
database types, you may get back a[dbnull]::Valuewhich is equivalent to$nullwithin the database, but in PowerShell, this was not equal to$nullso you can’t compare it directly. This change fromJoel Sallowallows you to compare both[dbnull]::Valueand[nullstring]::Valueto$nulland get$...

Note: When you use this switch, you can move a database that's currently a seeding source, which cancels the seed operation. Expand table Type: SwitchParameter Position: Named Default value: None Required: False Accept pipeline input: False Accept wildcard characters: False Applies to: Exchan...
If an attacker later compromises a machine that has logged this data, it may provide them with additional information with which to extend their reach. To prevent this dilemma, Windows 10 introduces Protected Event Logging. Protected Event Logging lets participating applications encrypt sensitive data ...
