Count total number of lines in a project excluding certain folders or files

Using the command:

wc -l + `find . -name \* -print` 

You can get the total number of lines of all files inside a folder.

But imagine you have some folders (for example li开发者_如何转开发braries), which you don't want to count their lines because you didn't write them.

So, how would you count the lines in a project excluding certain folders?


cloc has always been a great friend whenever I need to count lines of src-code. Using 2.6.29 linux kernel as an example:

$ cloc .

   26667 text files.
      26357 unique files.
          2782 files ignored.

With find, you can also "negate" matching conditions with !. For example, if I want to list all the .java files in a directory, excluding those containing Test:

find . -name "*.java" ! -name "*Test*"

Hope this helps!

Edit:

By the way, the -name predicate only filters file names. If you want to filter paths (so you can filter directories), use -path:

find . -path "*.java" ! -path "*Test*"


you could always exclude them by listing out the files using regular expressions, for example,

*.txt will include only txt files and so on...


I made an NPM package specifically for this usage, which allows you to call a CLI tool and providing the directory path and the folders/files to ignore

it goes like:

npm i -g @quasimodo147/countlines

to get the $ countlines command in your terminal

then you can do countlines . node_modules build dist
