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 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 read‐
       dir(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 }
