![]() To grab just the employee names from this string, I'll first attempt just to get the syntax right on Select-String.

We've got PowerShell's Select-String cmdlet. The grep utility allows a user to search text using some different options, but this utility doesn't exist in Windows. It doesn’t accept pipeline input and wild card characters are also not allowed.When writing PowerShell code and you need to search for text inside of a single string or an entire text file, where do you turn? If you've used Linux very much, you're probably familiar with the popular grep utility. NotMatch: It is used to find the non-matching occurrence. It accepts pipeline input also, wild card characters are accepted.ġ4. Path: It denotes the path of the files to be searched. It doesn’t accept pipeline input and wild card characters are also not allowed.ġ3. Pattern: This denotes that pattern that needs to be searched for.

No wild card characters are allowed, if the path has special characters it must be enclosed in single quotes. LiteralPath: It denotes the path of the files to be searched. It doesn’t accept pipeline input and wild card characters are also not allowed.ġ0. List: When this is used, only the first instance of matching is considered and returned for each file. It accepts pipeline input whereas wild card characters are not accepted.ĩ. It can either be a variable that holds a text or an expression. ![]() InputObject: It denotes the text to be searched. It can accept wild card characters whereas pipeline input is not allowed.Ĩ. Include: This denotes the list of items that needs to be included for matching. It can accept wild card characters whereas pipeline input is not allowed.ħ. Exclude: This denotes the list of items that needs to be excluded from matching.

If two numbers are mentioned, first number denotes the number of lines before the match and the number of lines after the match is determined by the second number. If only a single number is mentioned, that number determines the lines before and after the match. Context: This captures the number of lines before a match is found and the number of lines that there after the match. It doesn’t accept pipeline input and wild card characters are not accepted.ģ. By default, the matches are case-insensitive. CaseSensitive: It denotes that a case sensitive match must be performed. It doesn’t accept pipeline input and wild card characters are not accepted.Ģ.
