Search for string in text file powershell




















The Context parameter outputs the two lines before the first pattern match and three lines after the last pattern match. This example shows how the AllMatches parameter finds each pattern match in a line of text. By default, Select-String only finds the first occurrence of a pattern in a line of text. This example uses object properties that are found with the Get-Member cmdlet.

The Get-ChildItem cmdlet uses the Path parameter. Select-String uses the Pattern parameter to search each file for the string PowerShell. There's a line that contains two occurrences of the string PowerShell.

Matches property lists the first occurrence of the pattern PowerShell on each line. Length property counts the first occurrence of the pattern PowerShell on each line.

AllMatches finds each occurrence of the pattern PowerShell on each line. Length property increases because for each line, every occurrence of the pattern PowerShell is counted. The ToString result of the piped object isn't the same rich string representation produced by PowerShell's formatting system.

So, you may need to pipe the objects to Out-String first. Piping to Out-String converts the formatted output into a single multi-line string object. This means that when Select-String finds a match it outputs the whole multiline string. Piping to Out-String -String converts the formatted output into a multipel single-line string objects. This means that when Select-String finds a match it outputs only the matching line.

Indicates that the cmdlet searches for more than one match in each line of text. Without this parameter, Select-String finds only the first match in each line of text. When Select-String finds more than one match in a line of text, it still emits only one MatchInfo object for the line, but the Matches property of the object contains all the matches. This parameter is ignored when used in combination with the SimpleMatch parameter.

If you wish to return all matches and the pattern that you are searching for contains regular expression characters, you must escape those characters rather than using SimpleMatch. If you enter one number as the value of this parameter, that number determines the number of lines captured before and after the match. If you enter two numbers as the value, the first number determines the number of lines before the match and the second number determines the number of lines after the match.

For example, -Context 2,3. Unmarked lines are the context. The Context parameter doesn't change the number of objects generated by Select-String. Select-String generates one MatchInfo object for each match. The context is stored as an array of strings in the Context property of the object.

When the output of a Select-String command is sent down the pipeline to another Select-String command, the receiving command searches only the text in the matched line. The matched line is the value of the Line property of the MatchInfo object, not the text in the context lines. As a result, the Context parameter isn't valid on the receiving Select-String command. When the context includes a match, the MatchInfo object for each match includes all the context lines, but the overlapping lines appear only once in the display.

Specifies a culture name to match the specified pattern. The Culture parameter must be used with the SimpleMatch parameter. The default behavior uses the culture of the current PowerShell runspace session. The Culture parameter uses tab completion to scroll through the list of arguments that specify the available cultures. To list all available arguments, use the following command:. For more information about.

NET CultureInfo. Name property, see CultureInfo. Beginning with PowerShell 6. For more information, see the. NET documentation for Encoding. Using -and in the select-string doesnt seem to work. This is what I have so far Quite sure the -or doesn't work.

Any idea how I can do this? So basically I want to be able to do. It does exactly what you say - finds files where one of the first pair of strings is present and one of the second pair. It returns True for all 4 cases. If you want to know more about regular expression the best way to do what you want , take a look :. I believe the topic starter has stricter conditions than ones checked by the RegExp above. Did anyone actually read the question.

The search is for two strings in a file. If both strings are in the file then copy the file. This was introduced in version 3 of PowerShell. Finally, in PowerShell we can also filter out files based upon date and time quite easily. With this information, we can first off target two things. First, show me all Word documents, files only, on the entire C: drive, and keep the error messages to yourself, PowerShell.

This will include everything since AM the morning of that day. Finally we can also specify multiple paths in which we will do the search following, for example, the below command:.

A first method to search text string in files not in filenames we can use the Select-String cmdlet that expects the path as well as the pattern parameter to be strings, so we do not need to use quotation marks for either the pattern or the path. The output of this command will be zero or more lines in the format of file.

In addition to directly using the -Path parameter in the Select-String cmdlet, we can use the Get-Childitem cmdlet for more granular control over the files to be parsed. Luckily, SH, the answer to your question is no, you do not have to write a script to parse a folder full of files for a particular string. In fact, it was a topic that was tested in the Beginner Event 6 in the Scripting Games.

The solution is to use the Select-String cmdlet. One thing to keep in mind is that the Select-String cmdlet reads text files; it cannot read the more complicated file types such as.

When I attempted to search a folder containing the Word documents and pictures that make up a typical Hey, Scripting Guy! Blog post, Windows PowerShell displayed a bunch of gibberish in the console, and then locked up. This is shown in the following figure. The easy way to avoid producing gibberish is to specify the file types you want to search. The nice thing about the Select-String cmdlet is that it expects the path as well as the pattern parameter to be strings, so I do not need to use quotation marks for either the pattern or the path.

If I use the Get-Command cmdlet gcm is an alias for this cmdlet to examine the syntax for the Select-String cmdlet, I see that both the path and the pattern parameters will accept an array of strings. This means that I can use the wildcard character trick with the file extensions to look for multiple files at the same time.

To examine only the syntax of the Select-String cmdlet, I used the Get-Command cmdlet and piped the output to the Select-Object cmdlet select is an alias. I then chose to expand the definition property. The resulting command is shown here:. Because I can supply an array of strings to the path parameter, I can search for both.
