READDIR(3)                 GNU Awk Extension Modules                READDIR(3)

NAME
       readdir - directory input parser for gawk

SYNOPSIS
       @load "readdir"

       BEGIN { PROCINFO["readdir_override"] = any_value }  # optional

DESCRIPTION
       The readdir extension adds an input parser for directories.

       When this extension is in use, instead of skipping directories named on
       the  command line (or with getline), they are read, with each entry re‐
       turned as a record.

       The record consists of three fields separated by forward slash  charac‐
       ters.   The  first  two  are the inode number and the filename, and the
       third field is a single letter indicating the type of the file:  f  for
       file,  d for directory, b for a block device, c for a character device,
       p for a FIFO, l for a symbolic link, or s for a socket.

       On systems where the directory entry contains the file type, the  third
       field  is filled in from that information.  On systems without the file
       type information, the extension falls back to calling stat(2), in order
       to provide the information.  Thus the third field  should  never  be  u
       (unknown).

       Normally,  when  reading  directories,  you should set FS equal to "/".
       However, you may instead chose to  create  PROCINFO["readdir_override"]
       (with  any value). If this element exists when the directory is opened,
       then the extension automatically sets the fields  in  each  record  for
       you.

       By  default,  if  a directory cannot be opened (due to permission prob‐
       lems, for example), gawk will exit.  As with regular files, this situa‐
       tion can be handled using a BEGINFILE rule that checks ERRNO and prints
       an error or otherwise handles the problem.

EXAMPLE
       @load "readdir"
       ...
       BEGIN { FS = "/" }
       { print "file name is", $2 }
