![]() ![]() ![]() “get-process | findstr win” executed on average in 635.51057 millisecondsįiltering should always be done as early as possible in your code, the CMDLET will ‘grep’ for you. “gps| Out-String -Stream | sls win” executed on average in 559.78359 milliseconds The ‘proper’ PowerShell way would be to use the ‘Where-Object’ command: Get-Process | Where-Object ” executed on average in 55.802275 milliseconds You’re no longer dealing with a standard PowerShell object, so further piping and processing won’t really work. That’s great for simple stuff, but we’re sort of breaking what PowerShell does. It’s case sensitive though, so you need to use -i for case insensitive results. I say program because ‘findstr’ is not a PowerShell cmdlet, but it’s still native to Windows and works perfectly fine. An easier way would be to use the ‘ findstr‘ program (which also has a bunch of useful swtiches): get-process | findstr foo That works, but it’s still a lot clunkier than what a grep user would expect. ![]() Using the get-process example: get-process | where ProcessName -like "*foo* I had to do some research and asking around on this, because normally I’d filter out the property of the object I was looking at, and work with that. Even if a file has multiple occurrences of the pattern, it’s printed only once by findstr.In unix ps | grep “foo” help! □- Janet February 21, 2017Īs with poor cute cats, there’s more than one way to skin PowerShell. This command searches for the pattern in all *.log files, and then prints only the file names having the pattern. Print only the filenames finstr /M /C:"pattern" *.log ![]() You can add /N switch to the findstr command to print line numbers for the matched lines. Print line numbers for all the matched lines. Print only the lines where the given string is at the end of the line findstr /E /C:windows CLItips.txt You can add /B switch to indicate that the specified string should be in the beginning of the line. Print only the lines where the given string is at the beginning of the line. Adding ‘/M’ option to the command causes to print only the file names. You can customize the findstr command in the script to search in files with other extensions. The above command searches only text files. ‘pattern.txt ‘is the file having the strings(one per line) that need to be searched for. It's not available on Windows however, so you'll have to either use alternatives, or install third-party grep tools to emulate it. If you need to search for multiple strings, then you can do that with the below batch script. Using FindStr Linux's grep utility is a favorite among many sysadmins for its simple searching ability and familiar syntax. To search all the text files in the directory C:\data: findstr /I windows C:\data\*.txt You can use wildcard ‘*” to specify that all the files in a directory should be searched for the given string.įor example, to search for ‘windows’ in all the files in the current directory, you can use the below command. findstr /R *xyz filename.txt Search for text in all the files in a current directory grep-2.5.4-setup.exe grep global search regular expression (RE) and print out the line. Search for the occurrence of all words ending with ‘xyz’ in a file. Here the pattern can be specified using regular expressions. You can use regular expressions with findstr /R switch. C indicates that the search pattern has to be matched literally.įor example, to search for the string “Apple Ball Cat” in file Book.txt, the command would be as below findstr /C:"Apple Ball Cat" Book.txt Search with Regular Expressions Search for pattern with multiple words findstr /C:"word1 word2 word3." filename This command would print a line if it has has either the word ‘Apple’ or the word ‘Orange’ or both the words. Findstr "word1 word2 word3." filename.txt findstr "Apple Orange" fruits.txt Using findstr to grep Search In PowerShell There are a couple different search utilities in PowerShell, each with their own strengths. ![]()
