How would I count the total number of lines present in all the files in a git repository?
git ls-files
gives me a list of files tracked by git.
I'm looking for a command to cat
all those files. Something like
git ls-files | [cat all these files] | wc -l
回答1:
xargs
will do what you want:
git ls-files | xargs cat | wc -l
But with more information and probably better, you can do:
git ls-files | xargs wc -l
回答2:
git diff --stat 4b825dc642cb6eb9a060e54bf8d69288fbee4904
This shows the differences from the empty tree to your current working tree. Which happens to count all lines in your current working tree.
To get the numbers in your current working tree, do this:
git diff --shortstat `git hash-object -t tree /dev/null`
It will give you a string like 1770 files changed, 166776 insertions(+)
.

If you want this count because you want to get an idea of the project’s scope, you may prefer the output of CLOC (“Count Lines of Code”), which gives you a breakdown of significant and insignificant lines of code by language.
cloc $(git ls-files)
(This line is equivalent to git ls-files | xargs cloc
. It uses sh
’s $()
command substitution feature.)
Sample output:
20 text files.
20 unique files.
6 files ignored.

You will have to install CLOC first. You can probably install cloc
with your package manager – for example, brew install cloc
with Homebrew.
cloc $(git ls-files)
is often an improvement over cloc .
. For example, the above sample output with git ls-files
reports 471 lines of code. For the same project, cloc .
reports a whopping 456,279 lines (and takes six minutes to run), because it searches the dependencies in the Git-ignored node_modules
folder.

I've encountered batching problems with git ls-files | xargs wc -l
when dealing with large numbers of files, where the line counts will get chunked out into multiple total
lines.
Taking a tip from question Why does the wc utility generate multiple lines with "total"?, I've found the following command to bypass the issue:
wc -l $(git ls-files)
Or if you want to only examine some files, e.g. code:
wc -l $(git ls-files | grep '.*\.cs')

The best solution, to me anyway, is buried in the comments of @ephemient's answer. I am just pulling it up here so that it doesn't go unnoticed. The credit for this should go to @FRoZeN (and @ephemient).
git diff --shortstat `git hash-object -t tree /dev/null`
returns the total of files and lines in the working directory of a repo, without any additional noise. As a bonus, only the source code is counted - binary files are excluded from the tally.
The command above works on Linux and OS X. The cross-platform version of it is
git diff --shortstat 4b825dc642cb6eb9a060e54bf8d69288fbee4904
That works on Windows, too.
For the record, the options for excluding blank lines,
-w
/--ignore-all-space
,
-b
/--ignore-space-change
,
--ignore-blank-lines
,
--ignore-space-at-eol
don't have any effect when used with --shortstat
. Blank lines are counted.

This works as of cloc 1.68:
cloc --vcs=git

I was playing around with cmder (http://gooseberrycreative.com/cmder/) and I wanted to count the lines of html,css,java and javascript. While some of the answers above worked, or
pattern in grep didn't - I found here (https://unix.stackexchange.com/questions/37313/how-do-i-grep-for-multiple-patterns) that I had to escape it
So this is what I use now:
git ls-files | grep "\(.html\|.css\|.js\|.java\)$" | xargs wc -l
回答8:
I use the following:
git grep ^ | wc -l
This searches all files versioned by git for the regex ^
, which represents the beginning of a line, so this command gives the total number of lines!

This tool on github https://github.com/flosse/sloc can give the output in more descriptive way. It will Create stats of your source code:
- physical lines
- lines of code (source)
- lines with comments
- single-line comments
- lines with block comments
- lines mixed up with source and comments
- empty lines
回答10:
I did this:
git ls-files | xargs file | grep "ASCII" | cut -d : -f 1 | xargs wc -l
this works if you count all text files in the repository as the files of interest. If some are considered documentation, etc, an exclusion filter can be added.

: | git mktree | git diff --shortstat --stdin
Or:
git ls-tree @ | sed '1i\\' | git mktree --batch | xargs | git diff-tree --shortstat --stdin
回答12:
Try:
find . -type f -name '*.*' -exec wc -l {} +
on the directory/directories in question
