rexec

rexec [options] rhost command

Execute commands remotely. This client program connects to a remote host running rexecd, and passes it command. It uses login name and password for authentication. These can be passed on the command line using options below, provided through the $HOME/.netrc file or the environment variables REXEC_USER and REXEC_PASS. If it cannot determine the username and password, it will prompt the user for the information. Because it sends passwords to the remote system in clear text, use rexec only on a secure network. See ssh for a more secure alternative.

Options

-a

Send both error messages and output to standard out.

-b

When received locally, only echo signals SIGINT, SIGQUIT and SIGTERM to the remote process.

-c

Leave remote standard input open when the local input closes.

-d

Debugging mode. Echo commands sent locally.

-l username

Specify a different username for the remote login. Default is the same as your local username.

-p password

Specify the password for the remote account.

-n

Prompt user for name and password even if otherwise provided.

-s

Do not echo any signals to the remote process.
