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. \# .SH BUGS
