How can I count all the lines of code in a directory recursively

Question

We ve got a PHP application and want to count all the lines of code under a specific directory and its subdirectories  We don t need to ignore comments  as we re just trying to get a rough idea  wc -l   php   That command works great within a given directory  but it ignores subdirectories  I was thinking this might work  but it is returning 74  which is definitely not the case    find   -name    php    wc -l  What s the correct syntax to feed in all the files

If you need just the total number of lines in, let's say, your PHP files, you can use very simple one line command even under Windows if you have GnuWin32 installed. Like this:

cat `/gnuwin32/bin/find.exe . -name *.php` | wc -l

You need to specify where exactly is the find.exe otherwise the Windows provided FIND.EXE (from the old DOS-like commands) will be executed, since it is probably before the GnuWin32 in the environment PATH and has different parameters and results.

Please note that in the command above you should use back-quotes, not single quotes.

I wanted to check on multiple file types and was to lazy to calculate the total by hand  So I use this now to get the total in one go  find   -name    js  -or -name    php    xargs wc -l   grep  total     awk    SUM     1  print  1  END   print  quot Total text lines in PHP and JS quot  SUM      79351  15318  Total text lines in PHP and JS 94669  This allows you to chain multiple extension types you wish to filter on  Just add them in the -name    js  -or -name    php  part  and possibly modify the otuput message to your liking

You can use a utility called codel  link   It s a simple Python module to count lines with colorful formatting  Installation pip install codel  Usage To count lines of C   files  with  cpp and  h extensions   use  codel count -e  cpp  h  You can also ignore some files folder with the  gitignore format  codel count -e  py -i tests     It will ignore all the files in the tests  folder  The output looks like   You also can shorten the output with the -s flag  It will hide the information of each file and show only information about each extension  The example is below

More common and simple as for me  suppose you need to count files of different name extensions  say  also natives   wc   find   -type f   egrep  quot    h c cpp php cc  quot

WC -L     better use GREP -C    wc -l  Wrong  The wc command counts new lines codes  not lines  When the last line in the file does not end with new line code  this will not be counted  If you still want count lines  use  grep -c    Full example    This example prints line count for all found files total 0 find  path -type f -name  quot   php quot    while read FILE  do        You see  use  grep  instead of  wc   for properly counting      count   grep -c    lt   quot  FILE quot        echo  quot  FILE has  count lines quot       let total total count  in bash  you can convert this for another shell done echo TOTAL LINES COUNTED    total  Finally  watch out for the wc -l trap  counts enters  not lines

If you want to keep it simple  cut out the middleman and just call wc with all the filenames  wc -l  find   -name  quot   php quot    Or in the modern syntax  wc -l   find   -name  quot   php quot    This works as long as there are no spaces in any of the directory names or filenames  And as long as you don t have tens of thousands of files  modern shells support really long command lines   Your project has 74 files  so you ve got plenty of room to grow

First change the directory to which you want to know the number of lines  For example  if I want to know the number of lines in all files of a directory named sample  give  cd sample  Then try the command  wc -l    This will return the number of lines for each file and also the total number of lines in the entire directory at the end

None of the answers so far gets at the problem of filenames with spaces  Additionally  all that use xargs are subject to fail if the total length of paths in the tree exceeds the shell environment size limit  defaults to a few megabytes in Linux   Here is one that fixes these problems in a pretty direct manner  The subshell takes care of files with spaces  The awk totals the stream of individual file wc outputs  so it ought never to run out of space  It also restricts the exec to files only  skipping directories   find   -type f -name    php  -exec bash -c  wc -l  quot  0 quot           awk   s   1  END  print s

A straightforward one that will be fast  will use all the search filtering power of find  not fail when there are too many files  number arguments overflow   work fine with files with funny symbols in their name  without using xargs  and will not launch a uselessly high number of external commands  thanks to   for find s -exec   Here you go  find   -name    php  -type f -exec cat --        wc -l

If using a decently recent version of Bash  or ZSH   it s much simpler   wc -l      php   In the Bash shell this requires the globstar option to be set  otherwise the    glob-operator is not recursive  To enable this setting  issue  shopt -s globstar   To make this permanent  add it to one of the initialization files     bashrc     bash profile etc

You don t need all these complicated and hard to remember commands  You just need a Python tool called line-counter  A quick overview This is how you get the tool   pip install line-counter  Use the line command to get the file count and line count under current directory  recursively     line Search in  Users Morgan Documents Example  file count  4 line count  839  If you want more detail  just use line -d    line -d Search in  Users Morgan Documents Example  Dir A file C c                                             72 Dir A file D py                                           268 file A py                                                 467 file B c                                                   32 file count  4 line count  839  And the best part of this tool is  you can add a  gitignore-like configuration file to it  You can set up rules to select or ignore what kind of files to count just like what you do in   gitignore   More description and usage is here  https   github com MorganZhang100 line-counter
