STDERR output
Hi,
Need some help here on a script I'm writing. I know that STDERR is normally done is this manner:
script 2>stderr.out
However, if I wanted to output the stderr from a rsh command how do I do that?
Example:
su - username -c "rsh $hostname /opt/gilberteu/scriptname" 1>stdout 2>stderr
If the scriptname doesn't exist, an error will be shown on the screen instead of it going to the stderr file.
Any ideas?

Hi everyone,
KSH question: I know you can 'tee' STDOUT to have the output go to multiple targets; can you do the same with STDERR?
For example:
ls |tee /tmp/file.txt
Will redirect STDOUT to both the screen and the '/tmp/file.txt' file. Is there a way of doing the same thing for... (5 Replies)

Is there a way to send the syslog output for a given facility to stderr or stdout?
I do not want to use the "tail" command to achieve this, I would like it to go directly to stderr.
Thanks in advance (1 Reply)

RSH(1) General Commands Manual RSH(1)
NAME
rsh - remote shell
SYNOPSIS
rsh [-n] [-l username] host [command]
host [-n] [-l username] [command]
DESCRIPTION
Rsh connects to the specified host, and executes the specified command. 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 terminates when the remote command does.
The remote username used is the same as your local username, unless you specify a different remote name with the -l option. This remote
name must be equivalent (in the sense of rlogin(1)) to the originating account; no provision is made for specifying a password with a com-
mand.
If you omit command, then instead of executing a single command, 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. Thus the command
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the localfile localfile, while
rsh otherhost cat remotefile ">>" otherremotefile
appends remotefile to otherremotefile.
OPTIONS
-l username
Specify the remote user name.
-n Connect standard input of the remote command to /dev/null. Do this if rsh should not inadvertently read from standard input.
SEE ALSO
rcp(1), rlogin(1), rhosts(5).
BUGS
You cannot run an interactive command (like rogue(6) or vi(1)); use rlogin(1).
