184 Use 'tahoe cp' to copy files between a local filesystem and a Tahoe
185 virtual filesystem. Any FROM/TO arguments that begin with an alias
186 indicate Tahoe-side files, and arguments which do not indicate local
187 files. Directories will be copied recursively. New Tahoe-side directories
188 will be created when necessary. Assuming that you have previously set up
189 an alias 'home' with 'tahoe create-alias home', here are some examples:
191 tahoe cp ~/foo.txt home: # creates tahoe-side home:foo.txt
193 tahoe cp ~/foo.txt /tmp/bar.txt home: # copies two files to home:
195 tahoe cp ~/Pictures home:stuff/my-pictures # copies directory recursively
197 You can also use a dircap as either FROM or TO target:
199 tahoe cp URI:DIR2-RO:j74uhg25nwdpjpacl6rkat2yhm:kav7ijeft5h7r7rxdp5bgtlt3viv32yabqajkrdykozia5544jqa/wiki.html ./ # copy Zooko's wiki page to a local file
201 This command still has some limitations: symlinks, special files (device
202 nodes, named pipes), and non-ASCII filenames are not handled very well.
203 Arguments should probably not have trailing slashes. 'tahoe cp' does not
204 behave as much like /bin/cp as you would wish, especially with respect to
