Why only two lines of results for six lines of data? If you're coalescing please explain how. If you're filtering please explain why — roaima.

If that string could appear elsewhere, you need to adapt the script accordingly The following s ubstitute command contains a complex regular expression that is supposed to identify the correct parts you want to extract from the line:.
We are using the read command to input the file path also we are making use of -p argument to pass in a prompt to the user as a text message giving concise information before the user actually types in anything.
After the input has been stored in a preferable variable name we then move towards the actual reading of the file. To read in from a file, we are going to use while loop that reads in from a stream of characters of the file. We used to read and then a variable that stores the current character.
We output the character using echo. But the argument we have passed in to read i. If you want to go by more characters we can increment the -n to any desirable number. Skip to content. Asked yesterday. Active today. Viewed 50 times.

Don't post is as a comment, an image, a table or a link to an off-site service but use text and include it to your original question. Also, as this is not a free coding service, we'd appreciate seeing some attempt first. Thanks — James Brown.
But can you please show what do you have so far? I mean, the script. The below code reads the contents of the fruits. Get-Content reads and stores the content as an array, but how do you know that for sure?
First, save the content to a PowerShell object which you can then examine to determine the type. Each object represents a single line of text. Each item in a collection corresponds to an index number, and PowerShell indexes typically start at zero. The screenshot below shows that there are ten items in the string array. The array indexed the ten items from zero to nine.
You may notice that the Get-Content command is enclosed in a parenthesis. This notation tells PowerShell to run the command enclosed in the parenthesis first before other operations. What if you need to get the content in the last line? Thankfully, you do not need to know the total number of lines. Instead, use [-1] as the index, and Get-Content will display only the last line of the file. Use the TotalCount parameter of Get-Content to retrieve a specified number of lines from a text file.
The TotalCount parameter accepts a long value which means a maximum value of 9,,,,,, As you would expect, the result below displays only the top three lines from the beginning of the text file. In the previous example, you used the PowerShell Get-Content cmdlet to read a text file and limit the top results. It is also possible to achieve the opposite with PowerShell Get-Content.
Use the PowerShell Tail parameter to read a specified number of lines from the end of a file. After running the PowerShell tail command, the expected outcome will be limited to the last four lines of content, as shown in the image below.
