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

User · Answer

You want a simple for loop  total count 0 for file in   find   -name   php -print  do     count   wc -l  file      let total count  count done echo  quot  total count quot

lines 0   for file in   cpp   h   do lines      lines      wc -l  file   cut -d     -f 1        done   echo  lines

Giving out the longest files first  ie  maybe these long files need some refactoring love    and excluding some vendor directories    find   -name    php    xargs wc -l   sort -nr   egrep -v  libs tmp tests vendor    less

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

Similar to Shizzmo s answer  but uglier and more accurate  If you re using it often  modify it to suit and put it in a script  This example   Properly excludes paths that aren t your code  not traversed at all by find  Filters out compound extensions and other files you wish to ignore Only includes actual files of the types you specify Ignores blank lines Gives a single number as a total  find            -path   lib -o -path   node modules -o -path   vendor -o -path   any other path to skip -o -wholename   not this specific file php -o -name    min js  -o -name    min css     -prune    -type f    -name    php  -o -name    inc  -o -name    js  -o -name    scss  -o -name    css     -print0   xargs -0 cat   grep -vcE      space

You didn t specify how many files are there or what is the desired output  This may be what you are looking for  find   -name    php    xargs wc -l

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

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

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

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 the files are too many  better to just look for the total line count   find   -name    php    xargs wc -l   grep -i   total    awk   print  1

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

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

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

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
