Powershell get server list from file

You can add more properties if you want, but the ones here are enough for moving forward. This output is not ideal. With some effort, you could get rid of the header information, but then you might face other issues. For example what if your Environment for another server is called Dev and QA. You can perhaps then wrap your properties in single quotes and do other fancy stuff, but very quickly this becomes complex. JSON is the rage among all the kids these days, and this provides a simple and convenient solution.

Notice now you still have three servers, but you have more complete information about them. Save the above file. You could have more useful commands in there, but this shows how you can do different things depending on the environment or version.

If you left off the encapsulation, you would see something like:. This is because PowerShell would expand the entire object and then append the string. Most likely though, you will want to use the same script, but in different environments. Note in the first, there is a new block, which has to be the first block in the file, a param block. You can also assign default values if you wish. This makes it much easier for a new user to know what parameters are required.

As long as you enter the full parameter name as shown below, you can enter parameters in any order you want. This reduces errors. Save the modified script to Server Script with passed in parameter version 2.

The second change made was to pipe the loop through a Where-object cmdlet. This lets you reduce the verbiage a bit. Either this method or the previous one will give the same results, but this shortens the script a bit. I tend to prefer this method. Notice the user of. Environment value since now it is specific to the server in question.

This allows you to run the script against more than one environment at the same time. One caveat is, in this case, you must wrap your list of environments in quotes. You can also store related information control how the scripts run based on the environment or other factors.

Please rate your experience Yes No. Any additional feedback?

Module: Storage. Retrieves file share objects and their properties. Specifies the name of the file share to get. The first command uses the AsByteStream parameter to get the stream of bytes from the file. The Raw parameter ensures that the bytes are returned as a [System. If the Raw parameter was absent, the return value is a stream of bytes, which is interpreted by PowerShell as [System. Specifies that the content should be read as a stream of bytes.

A warning occurs when you use the AsByteStream parameter with the Encoding parameter. The AsByteStream parameter ignores any encoding and the output is returned as a stream of bytes. This parameter is not supported by any providers installed with PowerShell. To impersonate another user, or elevate your credentials when running this cmdlet, use Invoke-Command.

Specifies the delimiter that Get-Content uses to divide the file into objects while it reads. When reading a text file, Get-Content returns a collection of string objects, each of which ends with an end-of-line character. When you enter a delimiter that does not exist in the file, Get-Content returns the entire file as a single, undelimited object. You can use this parameter to split a large file into smaller files by specifying a file separator, as the delimiter.

The delimiter is preserved not discarded and becomes the last item in each file section. Delimiter is a dynamic parameter that the FileSystem provider adds to the Get-Content cmdlet. This parameter works only in file system drives. Currently, when the value of the Delimiter parameter is an empty string, Get-Content does not return anything.

This is a known issue. To force Get-Content to return the entire file as a single, undelimited string. Enter a value that does not exist in the file. Encoding is a dynamic parameter that the FileSystem provider adds to the Get-Content cmdlet.

This parameter is available only in file system drives. When reading from and writing to binary files, use the AsByteStream parameter and a value of 0 for the ReadCount parameter.

A ReadCount value of 0 reads the entire file in a single read operation. The default ReadCount value, 1, reads one byte in each read operation and converts each byte into a separate object, which causes errors when you use the Set-Content cmdlet to write the bytes to a file unless you use AsByteStream parameter.

Beginning with PowerShell 6. For more information, see the. NET documentation for Encoding. As of PowerShell 7. Specifies, as a string array, an item or items that this cmdlet excludes in the operation. The value of this parameter qualifies the Path parameter. Specifies a filter to qualify the Path parameter. The FileSystem provider is the only installed PowerShell provider that supports the use of filters. Filters are more efficient than other parameters, because the provider applies them when the cmdlet gets the objects rather than having PowerShell filter the objects after they are retrieved.

Force will override a read-only attribute or create directories to complete a file path. The Force parameter does not attempt to change file permissions or override security restrictions.

Specifies, as a string array, an item or items that this cmdlet includes in the operation. Wildcard characters are permitted. Specifies a path to one or more locations.

The value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks.

Single quotation marks tell PowerShell not to interpret any characters as escape sequences.
