 ### Example 1: Copy a named blob to another
 ```
-C:\PS> $destBlob = Copy-AzStorageBlob -SrcContainer "sourcecontainername" -SrcBlob "srcblobname" -DestContainer "destcontainername" -DestBlob "destblobname" 
+C:\PS> $destBlob = Copy-AzStorageBlob -SrcContainer "sourcecontainername" -SrcBlob "srcblobname" -DestContainer "destcontainername" -DestBlob "destblobname"
 ```
 
 This command copies a blob from source container to the destination container with a new blob name. 
 
 ### Example 2: Copy blob from a blob object
 ```
 C:\PS> $srcBlob = Get-AzStorageBlob -Container $containerName -Blob $blobName  -Context $ctx 
-C:\PS> $destBlob =  $srcBlob | Copy-AzStorageBlob  -DestContainer "destcontainername" -DestBlob "destblobname"  
+C:\PS> $destBlob =  $srcBlob | Copy-AzStorageBlob  -DestContainer "destcontainername" -DestBlob "destblobname"
 ```
 
 This command copies a blob from source blob object to the destination container with a new blob name.
 
 ### Example 3: Copy blob from a blob Uri
 ```
 C:\PS> $srcBlobUri = New-AzStorageBlobSASToken -Container $srcContainerName -Blob $srcBlobName -Permission rt -ExpiryTime (Get-Date).AddDays(7) -FullUri

+C:\PS> $destBlob = Copy-AzStorageBlob -AbsoluteUri $srcBlobUri -DestContainer "destcontainername" -DestBlob "destblobname"
 ```
 
 The first command creates a blob Uri of the source blob, with sas token of permission "rt". The second command copies from source blob Uri to the destination blob.
