PowerShell comparison operators compare values. There are four types of comparison operators: match, equality, replace, and containment. The –eq comparison is used to declare variables. Similarly, –lt stands for ‘less than,' –gt stands for ‘greater than,' and –one stands for ‘not equal.'
We use the PowerShell pipeline to connect two statements. In this case, the output of one statement becomes the input of the next.
The get-command in PowerShell is used to retrieve cmdlets. For example, if someone is looking for a cmdlet between E and K, the get-command would be - get-command [ E–K ] *
The following PowerShell commands must be run to map a network drive:
# PowerShell Network Drive Mapping
$( New-Object – ComObject Wscript.Network ) $Net = $( New-Object – ComObject Wscript.Network )
$Net.MapNetworkDrive( "S:", expertmyTectra ) )
The WQL (WMI Query Language) statement is the most basic method. This technique employs the ‘-query' to introduce ‘Select * from'.
In PowerShell, the next method after ‘Select' is Select-String. The matching pattern, phrase, and word are checked by the cmdlet in this scenario.
The final option is to use Select-Object.

The hash table in PowerShell is known as a dictionary. Essentially, it is a series that allows users to store data using a pair association known as "key-value." In this case, both "key" and "value" can be any length and data. To declare a hash table, users must use @ in front of curly braces.
PowerShell Array is a command-line tool for running scripts on remote computers. To create a PowerShell Array, users must first create a variable and then assign the PowerShell Array. PowerShell arrays are represented as a hashtable and are denoted with a “@” symbol.

We can do this in two ways:
get-wmiobject win32_service l where-object {$_name-like “*sql*”}
get-service sql*
where-object $_.name -like "*sql*" get-wmiobject win32 service
sql-get-service*
This can be put to use as follows:
PS C:> $server = gwmi -cl win32_computersystem
PS C:> $server.SystemType X86-based PC
