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 }
