UPSPIN(1) General Commands Manual UPSPIN(1)


upspin - global name space to name all your files


upspin [arguments]


Upspin is an experimental project to build a framework for naming and sharing files and other data securely, uniformly, and globally: a global name system of sorts.

It is not a file system, but a set of protocols and reference implementations that can be used to join things like file systems and other storage services to the name space.

Performance is not a primary goal. Uniformity and security are.


Run upspin --help for more details. Help for individual commands is available using e.g. upspin cp --help.
