Is there a write opposite to "svn cat"?

Hi all,

The “svn cat” command will read a file from a (in my case local file based) repository to stdout. Is there an equivalent to write into a repository from the svn command line?

First prize from stdin, second prize from a local file on disk.

“svn import” comes close, but cannot be run twice, as the second time the command is run you get the following error:

svn: E150002: Path 'file:///var/lib/svn/postgres/database.sql' already exists

I know that it is possible to autocommit via WebDAV, but this is a local repo.

Regards,
Graham
