chirp_fuse(1)

NAME

chirp_fuse - create a FUSE mount point with virtual access to remote chirp servers

SYNOPSIS

chirp_fuse [options] <mount path>

DESCRIPTION

You can attach to a Chirp filesystems by using the FUSE package to attach Chirp as a kernel filesystem module. Unlike parrot(1), this requires superuser privileges to install the FUSE package, but will likely work more reliably on a larger number of programs and environments. Using FUSE allows for transparent access to a Chirp server via the local filesystem. This allows user applications to use a Chirp store unmodified.

Once you have installed and permissions to use FUSE, simply run chirp_fuse with the name of a directory on which the filesystem should be mounted.

For complete details with examples, see the Chirp User's Manual.
