NAME

       readdir - directory input parser for gawk

SYNOPSIS

       @load "readdir"

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 returned as a record.

       The record consists of three fields. The first two are the inode number and the filename, separated by  a
       forward  slash  character.  On systems where the directory entry contains the file type, the record has a
       third field which 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, s for a socket, and u
       (unknown) for anything else.

       On systems without the file type information, the third field is always u.

NOTES

       On GNU/Linux systems, there are filesystems that don't support the d_type entry (see readdir(3)), and  so
       the  file  type  is always u.  You can use the filefuncs extension to call stat() in order to get correct
       type information.

EXAMPLE

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