Getting the exit status of a remote command
Hi to everyone.
How can I get the exit status from a remote command executed with rexec?
machine A has RedHat Linux 9 and the remote machine B has SCO UNIX.
Code:
rexec -l user -p password host sh /u/files/scripts/seq_cal.sh 2006 08
I want the exit status returned by seq_cal.sh not the one returned by rexec. It always return 0, that means its execution was okay.
Thanks

rexec(3x) rexec(3x)
Name
rexec - return stream to a remote command
Syntax
rem = rexec(ahost, inport, user, passwd, cmd, fd2p);
char **ahost;
u_short inport;
char *user, *passwd, *cmd;
int *fd2p;
Description
The subroutine looks up the host *ahost using returning -1 if the host does not exist. For further information, see Otherwise *ahost is
set to the standard name of the host. If a username and password are both specified, then these are used to authenticate to the foreign
host. If all this fails, the user is prompted for the information.
The port inport specifies which well-known DARPA Internet port to use for the connection; it will normally be the value returned from the
call ``getservbyname("exec", "tcp")''. For further information, see The protocol for connection is described in detail in
If the call succeeds, a socket of type SOCK_STREAM is returned to the caller and given to the remote command as stdin and stdout. If fd2p
is nonzero, then an auxiliary channel to a control process will be set up, and a descriptor for it will be placed in *fd2p. The control
process will return diagnostic output from the command (unit 2) on this channel and will also accept bytes on this channel as being UNIX
signal numbers, to be forwarded to the process group of the command. If fd2p is 0, then the stderr (unit 2 of the remote command) will be
made the same as the stdout and no provision is made for sending arbitrary signals to the remote process, although you may be able to get
its attention by using out-of-band data.
