You can use Select-String similar to grep. Select-String searches for text or text patterns in the input string or file. The Select-String cmdlet uses regular expression matching to search for text patterns in input strings and files. Select-String cmdlet in Powershell works similar to grep in UNIX and findstr in PowerShell. Putting this together your command line version should be: ls /some/path/some/dir/ | grep 'some_mask_.*\.txt' | wc -lĪnd the script: iFiles=`ls /some/path/some/dir/ | grep 'some_mask_.*\.txt' | wc -l` PowerShell Grep equivalent cmdlet is Select-String which uses regular expressions to search string in files. Specifies the encoding used for text files. How do I grep text in PowerShell The Select-String cmdlet searches for text and text patterns in input strings and files.

Connect and share knowledge within a single location that is structured and easy to search. In addition you need to write the pattern as a regexp and not as a wildcard match (which bash uses for matching). Does PowerShell have a grep command The Select-String cmdlet searches for text and text patterns in input strings and files. I found a post about users that wanted to use grep in PowerShell. If you want to ensure that the pattern is used by grep then you need to enclose it in single quotes. $reader = New-Object -ArgumentList $pdf.FullNameįor($page = 1 $page -le $reader.The problem here is that grep some_mask_*.txt is expanded by the shell and not by grep, so most likely you have a file in the directory where grep is executed which matches some_mask_*.txtand that filename is then used by grep as a filter. The grep command in Linux is widely used for parsing files and searching for useful data in the outputs of different commands. You can run with this to rename files if matches are found, move them to categorized folders, and the likes.ĮDIT: Github page for itextsharp indicates it is end-of-life and links to Itext7 (dual licensed as AGPL/Commercial software, seems free for non-commercial use.)

As of now I've tried the following: get-childitem -Recurse | where The crucial point here is that the keyword will be in the content (body of a pdf, cell of an excel etc.) and not in the filename. I would like to have a powershell script that basically executes a series of scripts looking for all the files of a certain format containing specific keywords and outputting each list to a separate csv. The idea is that, for a certain format and a certain type, I know what keywords to look for in the file's contents. I'm interested in creating a catalogue by type. The files are in no particular order and might as well be looked at as a single list. ![]() If I use the Get-Command cmdlet ( gcm is an alias for this cmdlet) to examine the syntax.
