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


chirp_fuse [options] <mount path>


You can attach to a Chirp filesystems by using the FUSE package to attach Chirp as a kernel filesystem module. Unlike parrot_run(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.


  • -a,--auth=<flag>
    Require this authentication mode.
  • -b,--block-size=<bytes>
    Block size for network I/O. (default is 65536s)
  • -d,--debug=<flag>
    Enable debugging for this subsystem.
  • -D,--no-optimize
    Disable small file optimizations such as recursive delete.
  • -f,--foreground
    Run in foreground for debugging.
  • -i,--tickets=<files>
    Comma-delimited list of tickets to use for authentication.
  • -m,--mount-options=<option>
    Pass mount option to FUSE. Can be specified multiple times.
  • -o,--debug-file=<file>
    Write debugging output to this file. By default, debugging is sent to stderr (":stderr"). You may specify logs to be sent to stdout (":stdout") instead.
  • -t,--timeout=<timeout>
    Timeout for network operations. (default is 60s)
  • -v,--version
    Show program version.
  • -h,--help
    Give help information.


  • CHIRP_CLIENT_TICKETS Comma delimited list of tickets to authenticate with (same as -i).


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


To create and use a FUSE mount point for access to remote chirp servers:

% cd /tmp/chirp-fuse
% ls
% cd host:port
% cat foo/bar
% exit
