make_growfs

NAME

make_growfs - generate directory listings for the GROW filesystem

SYNOPSIS

make_growfs [options] <directory>

DESCRIPTION

make_growfs prepares a local filesystem to be exported as a GROW filesystem which can be accessed by parrot_run(1). Given a directory as an argument, it recursively visits all of the directories underneath and creates files named .__growfsdir that summarize the metadata of all files in that directory.

Once the directory files are generated, the files may be accessed through a web server as if there were on a full-fledged filesystem with complete metadata.

OPTIONS

	-v		Give verbose messages.
	-K		Create checksums for files. (default)
	-k		Disable checksums for files.
	-f		Follow all symbolic links.
	-F		Do not follow any symbolic links.
	-a		Only follow links that fall outside the root. (default)
	-h		Show help text.

EXIT STATUS

On success, returns zero. On failure, returns non-zero.

EXAMPLES

Suppose that your university web server exports the directory /home/fred/www as http://www.somewhere.edu/fred. To create a GROW filesystem, put whatever files and directories you like into /home/fred/www. Then, run the following to generate the GROW data:

% make_growfs /home/fred/www

Now that the GROW data is generated, you can use parrot_run(1) to treat the web address as a read-only filesystem:

% parrot_run bash

% cd /growfs/www.somewhere.edu/fred
% ls -la
