How to Recursively List All Files and Directories

Recursively list all files in a directory including files in symlink directories

The -L option to ls will accomplish what you want. It dereferences symbolic links.

So your command would be:

ls -LR

You can also accomplish this with

find -follow

The -follow option directs find to follow symbolic links to directories.

On Mac OS X use

find -L

as -follow has been deprecated.

How to recursively list all files and directories

How about this:

find . -exec ls -dl \{\} \; | awk '{print $3, $4, $9}'

How to recursively list all the files in a directory in C#?

This article covers all you need. Except as opposed to searching the files and comparing names, just print out the names.

It can be modified like so:

static void DirSearch(string sDir)
{
    try
    {
        foreach (string d in Directory.GetDirectories(sDir))
        {
            foreach (string f in Directory.GetFiles(d))
            {
                Console.WriteLine(f);
            }
            DirSearch(d);
        }
    }
    catch (System.Exception excpt)
    {
        Console.WriteLine(excpt.Message);
    }
}

GONeale mentions that the above doesn't list the files in the current directory and suggests putting the file listing part outside the part that gets directories. The following would do that. It also includes a Writeline line that you can uncomment, that helps to trace where you are in the recursion that may help to show the calls to help show how the recursion works.

            DirSearch_ex3("c:\\aaa");
            static void DirSearch_ex3(string sDir)
            {
                //Console.WriteLine("DirSearch..(" + sDir + ")");
                try
                {
                    Console.WriteLine(sDir);

                    foreach (string f in Directory.GetFiles(sDir))
                    {
                        Console.WriteLine(f);
                    }

                    foreach (string d in Directory.GetDirectories(sDir))
                    {
                        DirSearch_ex3(d);
                    }
                }
                catch (System.Exception excpt)
                {
                    Console.WriteLine(excpt.Message);
                }
            }

How can I recursively find all files in current and subfolders based on wildcard matching?

Use find:

find . -name "foo*"

find needs a starting point, so the . (dot) points to the current directory.

How to list all files of a directory recursively in c

I can't for the life of me think why anybody would want to enumerate directories by calling main() recursively. But, since I can't resist a pointless challenge, here's a version that does. Do I get the prize for "most fruitless waste of ten minutes?" ;)

#include <stdio.h>
#include <string.h>
#include <dirent.h>
#include <errno.h>
#include <stdlib.h>

int main (int argc, char **argv)
  {
  const char *path;
  if (argc != 2) path = "/etc"; /* Set starting directory, if not passed */
  else
    path = argv[1];

  DIR *dir = opendir (path);
  if (dir)
    {
    struct dirent *dp;
    while ((dp = readdir(dir)) != NULL)
      {
      if (dp->d_name[0] != '.')
        {
        char *fullpath = malloc (strlen (path) + strlen (dp->d_name) + 2);
        strcpy (fullpath, path);
        strcat (fullpath, "/");
        strcat (fullpath, dp->d_name);
        if (dp->d_type == DT_DIR)
          {
          char **new_argv = malloc (2 * sizeof (char *));
          new_argv[0] = argv[0];
          new_argv[1] = fullpath;
          main (2, new_argv);
          free (new_argv);
          }
        else
          printf ("%s\n", fullpath);
        free (fullpath);
        }
      }
    closedir(dir);
    }
  else
    fprintf (stderr, "Can't open dir %s: %s", path, strerror (errno));
  return 0;
  }

Recursively list files in Java

Java 8 provides a nice stream to process all files in a tree.

try (Stream<Path> stream = Files.walk(Paths.get(path))) {
    stream.filter(Files::isRegularFile)
          .forEach(System.out::println);
}

This provides a natural way to traverse files. Since it's a stream you can do all nice stream operations on the result such as limit, grouping, mapping, exit early etc.

UPDATE: I might point out there is also Files.find which takes a BiPredicate that could be more efficient if you need to check file attributes.

Files.find(Paths.get(path),
           Integer.MAX_VALUE,
           (filePath, fileAttr) -> fileAttr.isRegularFile())
        .forEach(System.out::println);

Note that while the JavaDoc eludes that this method could be more efficient than Files.walk it is effectively identical, the difference in performance can be observed if you are also retrieving file attributes within your filter. In the end, if you need to filter on attributes use Files.find, otherwise use Files.walk, mostly because there are overloads and it's more convenient.

TESTS: As requested I've provided a performance comparison of many of the answers. Check out the Github project which contains results and a test case.

How to recursively walk through a directory and print all files in C?

Here is a recursive code that does that:

void sprint(char *filename, char * dirToOpen, int level = 0)
{
    DIR *dir;
    struct dirent *entry;
    struct stat s;

    if (!(dir = opendir(dirToOpen)))
        return;
    if (!(entry = readdir(dir)))
        return;

    do
    {
        if(lstat(dirToOpen, &s) == 0 && S_ISDIR(s.st_mode)) /*if it's a directory*/
        {
            char path[1024];
            int len = snprintf(path, sizeof(path)-1, "%s/%s", dirToOpen, entry->d_name); /*makes pathname*/
            path[len] = 0;
            if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) /*if the directory isn't . or ..*/
                continue;
            printf("%*s[%s]\n", level * 2, "", entry->d_name);
            sprint(filename ,path, level + 1);
        }
        else
        {
            if(strcmp(entry->d_name, filename) == 0 || strcmp(filename, ".") == 0) /*if entry name corresponds to filename, print it*/
             printf("%*s- %s\n", 2, "", entry->d_name);
        }
    } while (entry = readdir(dir)); /*while there are more entries to read*/
    closedir(dir);
}

Call it with sprint(".", "."); to recursively walk through a directory and print out all of the files.
