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

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  re-
       turned 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 de-
       vice, p for a FIFO, l for a symbolic link, s for a socket.

       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.

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