cu telno [ -t ] [ -s speed ] [ -a acu ] [ -l line ] DESCRIPTION
Cu calls up another UNIX system, a terminal, or possibly a non-UNIX system. It manages an interactive conversation with possible transfers of text files. Telno is the telephone number, with minus signs at appropriate places for delays. The -t flag is used to dial out to a terminal. Speed gives the transmission speed (110, 134, 150, 300, 1200); 300 is the default value. The -a and -l values may be used to specify pathnames for the ACU and communications line devices. They can be used to override the fol- lowing built-in choices: -a /dev/cua0 -l /dev/cul0 After making the connection, cu runs as two processes: the send process reads the standard input and passes most of it to the remote sys- tem; the receive process reads from the remote system and passes most data to the standard output. Lines beginning with `~' have special meanings. The send process interprets the following: ~. terminate the conversation. ~EOT terminate the conversation ~<file send the contents of file to the remote system, as though typed at the terminal. ~! invoke an interactive shell on the local system. ~!cmd ... run the command on the local system (via sh -c). ~$cmd ... run the command locally and send its output to the remote system. ~%take from [to] copy file `from' (on the remote system) to file `to' on the local system. If `to' is omitted, the `from' name is used both places. ~%put from [to] copy file `from' (on local system) to file `to' on remote system. If `to' is omitted, the `from' name is used both places. ~~... send the line `~...'. The receive process handles output diversions of the following form: ~>[>][:]file zero or more lines to be written to file ~> In any case, output is diverted (or appended, if `>>' used) to the file. If `:' is used, the diversion is silent, i.e., it is written only to the file. If `:' is omitted, output is written both to the file and to the standard output. The trailing `~>' terminates the diver- sion. The use of ~%put requires stty and cat on the remote side. It also requires that the current erase and kill characters on the remote sys- tem be identical to the current ones on the local system. Backslashes are inserted at appropriate places. The use of ~%take requires the existence of echo and tee on the remote system. Also, stty tabs mode is required on the remote system if tabs are to be copied without expansion. FILES

Exit code is zero for normal exit, nonzero (various values) otherwise. BUGS
The syntax is unique. CU(1C)

RSH(1)							    BSD General Commands Manual 						    RSH(1)

rsh -- remote shell SYNOPSIS
rsh [-Kdnx] [-k realm] [-l username] host [command] DESCRIPTION
Rsh executes command on host. Rsh copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard error of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rsh normally termi- nates when the remote command does. The options are as follows: -K The -K option turns off all Kerberos authentication. -d The -d option turns on socket debugging (using setsockopt(2)) on the TCP sockets used for communication with the remote host. -l By default, the remote username is the same as the local username. The -l option allows the remote name to be specified. Kerberos authentication is used, and authorization is determined as in rlogin(1). -n The -n option redirects input from the special device /dev/null (see the BUGS section of this manual page). If no command is specified, you will be logged in on the remote host using rlogin(1). Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote machine. For example, the command rsh otherhost cat remotefile >> localfile appends the remote file remotefile to the local file localfile, while rsh otherhost cat remotefile ">>" other_remotefile appends remotefile to other_remotefile.

rlogin(1), kerberos(3), krb_sendauth(3), krb_realmofhost(3) HISTORY
The rsh command appeared in 4.2BSD. BUGS
If you are using csh(1) and put a rsh in the background without redirecting its input away from the terminal, it will block even if no reads are posted by the remote command. If no input is desired you should redirect the input of rsh to /dev/null using the -n option. You cannot run an interactive command (like rogue(6) or vi(1)) using rsh; use rlogin(1) instead. Stop signals stop the local rsh process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain here. Linux NetKit (0.17) August 15, 1999 Linux NetKit (0.17)
