Powershell split file by delimiter

PowerShell uses the Split function to split a string into multiple substrings. The function uses the specified delimiters to split the string into sub strings. The default character used to split the string is the whitespace. Three types of elements are associated with the split function. They are delimiter, the maximum number of substrings and options related to delimiter, either SimpleMatch or Multiline. Delimiter: The default delimiter is whitespace.

Other delimiters such as patterns, tabs, and backspace can also be used. Maximum number of Substrings: By default, the function returns all the possible substrings. We can also limit them using this element. Multiple strings can also be specified. The default delimiter is whitespace including tab and a newline character. The delimiter character is by default omitted in all the substrings, to include them it must be enclosed within parenthesis.

By default, all the possible substrings are generated. If the substrings are more than the specified number, then the leftover substrings are appended to the final substring. Non-negative values are allowed, zero returns all the substrings. It is enclosed within the braces and must evaluate either to true or false. The syntax for options is below and it can only be used when the Max-SubStrings parameter is used.

Split "-". Split ",". Split ". This example will show how to split and generate substring based on regex and to split MAC addresses. The split path is used to return the mentioned part in a path. It can be a parent folder, a file name or a sub folder.

Thus, the article is covered in detail about the split string method in PowerShell.Microsoft Scripting Guy, Ed Wilson, is here. Dude, dude, dude, or dudette, as the case may be I still cannot find my teapot after our move.

It is not a major crisis yet, but I do miss blending my own teas with my own herbs. And of course, my various tins of teas and herbs are sitting here, just waiting for me to locate the teapot. On the bright side, I did pick up some nice tea bags when the Scripting Wife and I were in Europe, so it is not a total loss. In fact, I got a rather nice oolong tea in little triangle sachets that is actually not bad. The Split method from the System. String class is not a static method.

This means that when I have a string, I can gain access to the Split method. But if I do not have a string, I cannot access it. Split Method lists six overloads for this method. So I have a lot of flexibility on how I might want to use the method. I will not discuss all six overloads today, but I will discuss the three main ways of using the method:. One of the cool things about the Split method is that it will accept an array of things upon which to split.

Therefore, I can split on one or more Unicode characters. For example, the right curly brace is [char]0XD. The first thing I need is a string with Unicode characters embedded inside it. So here is my string:. Now I need to create an array of two characters to use to split the string. Here is what I come up with the first time:. And this command works. Here is a screenshot of the string, my split characters, and the associated output:.

What is cool is that I can do this same thing in reverse. Here is an example of reversing the process:. The option to specify an array of strings to use for splitting a string offers a lot of possibilities. The StringSplitOptions enumeration also offers a way to control the return of empty elements.

The first thing I need to do is to create a string.

PowerShell Split String

Here is my string:. Very cool. It also rocks. I mean dude. Now, I need to specify a separator. Now, I need to create my StringSplitOption. There are two options: None and RemoveEmptyEntries.

The first time I run the command, I will remove the empty entries. So here is that command:. When I change the option to NoneI see that there is one extra space at the end of the line.One popular question involving strings with PowerShell involves characters which we can treat as delimiters in strings where multiple instances of those characters may be present, such as a semi-colon in a log error that appears six or seven times in the error message.

Developers may want to parse some parts, such as the first or last part of the message, or middle part of the message from the string. In this tip we look at some methods we can use on strings to return pieces of one string where multiple instances of a character may exist.

PowerTip: Use PowerShell to Read Tab Delimited File

In the first line, we take the substring starting at the 0th character nothing to the first character, returning a c. The substring method requires the starting character and requires the length. The IndexOf method returns the first instance of the character we pass in or reports a negative if the character does not exist. We can use both of these methods to get the left set of characters from the first comma, which we do in line three.

The split method breaks the string into an array where the character we pass in to the method in this case, a comma separates each element in the array. So, the first element of the array is comma one, the second is comma two and the fourth is comma four.

Remember that arrays begin at the 0th character, not the first. We can see another example of this by using a foreach loop and iterating over each element in the array:. When parsing strings, two popular functions we tend to re-use is parsing right or left of a character when used as a delimiter.

Similar to T-SQL, we can use the replace function for measuring a string without characters. In the below examples, we see this being done with semicolons, vertical bars and periods.

We get the length of each of these strings without the chosen characters by using the replace method and length property. We can use the above logic to determine how many of each of these specific characters semicolons, vertical bars, and periods are in a string. We can use this logic to get the right side of a string from a set of delimiters fourth example below thisas this passes in the final delimiter number which allows our Split method to return the final part of the string after the last delimiter.

In using the Length property and Split and Replace methods, we can get the right or left side of a string from a delimiter. We can also use the Split method to get part of a string from a numbered delimiter, like we saw in some of the above examples. We can use these same functions to get strings between two delimiters, which we see below this. Because we may sometimes forget which method to use or want a function that makes it easier to get this information faster for data, the below function allows us to get the below quickly from a line of characters where we want to extract data based on a character.

It requires two parameters, the string and the character and allows us to make a selection with getting everything right or left to a character or parsing the string after a character by entering the Nth number of that character, if there are multiple instances of the character, and finally a possible parameter in case we want to get string between two identical characters.

Note: your email address is not published.Wait, it takes a script block? No way! Could this mean that we can split on two different delimiters? Can we go further? Scriptblocks are great but can we do better? Personally I prefer the second one, brevity wins out overall, plus reading this it just seems easier to understand. Then why are we adding it!!!

However, there is a worry that people cannot be happy within this state. There is a worry that they cannot see the improvements that they have achieved.

But what about if there are multiple databases being actioned in the same job? What about if we are trying to parse the log files and want to get the different database names from these lines? Rate this:. Like this: Like LoadingI want to be able to "split" the line so that the information appears in one column and make a human readable report.

Is it truly tab delimited? Can't tell here as it appears to have spaces between the columns. You may also want to look at the ConvertFrom-Csv cmdlet where you can specify the delimiter and the column headings take a look at example 3. If it's possible to go to comma delimited, that's usually easier to work with. Humans have a hard time differentiating white space. This format is the way the incoming file will be. I have not looked at ConvertFrom-csv yet.

Thank you.

Are the fields a fixed width? If so, do you know which columns the fields start and stop in? There are all sorts of ways to do this in PowerShell. What would be more helpful is if you posted about five lines of data.
