.SH NAME

readdir \- directory input parser for gawk

.SH SYNOPSIS

.ft CW

@load "readdir"

.ft R

.SH DESCRIPTION

The

.I readdir

extension

adds an input parser for directories.

.PP

When this extension is in use, instead of skipping directories named

on the command line (or with

.BR getline ),

they are read, with each entry returned as a record.

.PP

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:

.B f

for file,

.B d

for directory,

.B b

for a block device,

.B c

for a character device,

.B p

for a FIFO,

.B l

for a symbolic link,

.B s

for a socket, and

.B u

(unknown) for anything else.

.PP

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

.BR u .

.SH NOTES

On GNU/Linux systems, there are filesystems that don't support the

.B d_type

entry (see

.IR readdir (3)),

and so the file type is always

.BR u .

You can use the

.I filefuncs

extension to call

.I stat()

in order to get correct type information.
