What is the Windows equivalent of the Linux/Unix command wc -l?
Basically, how do you count the number of lines output from a command on the Windows command line?
4 Answers
The Linux/Unix "line count" command, wc -l, has a Windows equivalent find /c /v "".
How does this work?
According to Raymond Chen of the The Old New Thing, this functions as such since
It is a special quirk of the
findcommand that the null string is treated as never matching.
The inverted (/v) count (/c) thus effectively counts all the lines;
hence, the line count.
Example usage
To count the number of modified files in a subversion working copy:
svn status -q | find /c /v ""
Such a command can be used to mark a build as "dirty" if the count is not 0, i.e. there are uncommitted changes in the working copy.
To obtain a line count of all your Java files:
(for /r %f in (*.java) do @type "%f") | find /c /v ""
The command find /c /v "" can also be added to a batch file if required.
Remember to duplicate the % characters (%%f) in batch files.
PowerShell
A working PowerShell equivalent is Measure-Object -line — some additional formatting is required though, e.g. a directory listing for simplicity:
(ls | Measure-Object -line).Lines

find.exe lives in "Windows\System32" if your Path has another 'find' you will need to profile the path.– ChetSCommented Jun 28, 2021 at 15:20

This worked for me using triple quote as in this answer i.e.
ls | find /c /v """"""– pjpscrivCommented Nov 3, 2022 at 2:31 -
(ls | Measure-Object -line).Lines, exactly what I was looking for ;), and @pjpscriv, for mels | find /c /v """"""does not work since it does not count only files but also all empty lines and tables header around, whileMeasure-Objectmethod actually gives me 28 where I have 28 files,findstrmethod gives me 37 (file lines + extra lines).– gluttonyCommented Aug 11, 2023 at 9:32
In PowerShell, to obtain a line count of all your java files:
type *.java | Measure-Object -line

23Thanks @mic84. The question is about Windows command line. And Microsoft is trying to replace CMD with PowerShell: networkworld.com/article/3143196/windows/… So this is a quite useful answer.– crestorCommented Aug 7, 2018 at 10:41

This inspired me to try adding this to my
Microsoft.PowerShell_profile.ps1file:function wc () { Measure-Object -c -l -w }(it did not work as expected.)– MarkHuCommented Jul 14, 2023 at 22:16
Use "Count":
(Get-AppXPackage|?{!$_.InstallLocation}).Count
(ls).Count

findstr /n /r .
This is a limited regex, so /n shows the line number of the match, and "." is match any char.

8The question isn’t how to display the file with line numbers; the question is how to determine the number of lines in the file. Commented Jul 16, 2019 at 0:29

1Look at the number of the last line, and that's how many lines are in the file. The "find" command works, too, but maybe findstr will be useful in some cases. I have found it to be. Commented Jul 19, 2019 at 19:16

4That’s not a very user-friendly answer, especially given that we’ve received a couple of other answers that are more direct. But, if that’s your answer, then please edit your answer to make it clearer and more complete. Commented Jul 19, 2019 at 19:48

3the point is for automation scripting. No scripts will "look" at the line number to store the number of lines in a variable for further computation. And flooding the screen with unnecessary information lines and wasting CPU cycles are definitely not good– phuclvCommented Jul 26, 2022 at 1:42
