NAME

6       readdir - directory input parser for gawk
7

SYNOPSIS

9       @load "readdir"
10

DESCRIPTION

12       The readdir extension adds an input parser for directories.
13
14       When this extension is in use, instead of skipping directories named on
15       the command line (or with getline), they  are  read,  with  each  entry
16       returned as a record.
17
18       The record consists of three fields. The first two are the inode number
19       and the filename, separated by a forward slash character.   On  systems
20       where  the  directory  entry  contains  the file type, the record has a
21       third field which is a single letter indicating the type of the file: f
22       for  file,  d  for  directory,  b for a block device, c for a character
23       device, p for a FIFO, l for a symbolic link, s  for  a  socket,  and  u
24       (unknown) for anything else.
25
26       On systems without the file type information, the third field is always
27       u.
28

NOTES

30       On GNU/Linux systems, there are  filesystems  that  don't  support  the
31       d_type  entry  (see readdir(3)), and so the file type is always u.  You
32       can use the filefuncs extension to call stat() in order to get  correct
33       type information.
34

EXAMPLE

36       @load "readdir"
37       ...
38       BEGIN { FS = "/" }
39       { print "file name is", $2 }
