How can we redirect std err and std ouput in KSH

[jaigs_27]

I am working on Shell script but on Solaris server (/bin/ksh is default) and not able to redirect the Std Err and Std Output to a file..following is my code

ssh hostname | grep "omega" /home/ >& test.log

nothing is going in test.log

Try this:

ssh hostname | grep "omega" /home/ 1> test.log 2>&1

still not writing in a file

Have you considered the possibility that you're not getting any output at all?

[jaigs_27]

test.log file has to be created at runtime and I am able to see error message on the screen but it should store in to the test.log.

error message was "connection refused"

That's output of the ssh command. It's failing before you can even get to directing the output to a logfile. The command I gave you will direct standard out and standard error of the grep command to test.log.

Ohhh sorry misunderstood.

But is there any way so that I can store that output too in a log file?

[Thrillhouse]

I guess you could try the following:

ssh hostname 1> test.log 2>&1 | grep "omega" /home/ 1>> test.log 2>&1

to get all error and output from both commands into the log but I'm not sure if that will work. I don't have ssh installed on the machine I test ksh with so I can't test it. Maybe one of the scripting gurus will chime in.

Now that I think about it, my last recommendation won't work as the output will be written to the log file. Do you have to authenticate to this machine or is it public key auth?

ssh hostname | grep "omega" /home/ >& test.log

What is it you're expecting this to do? i.e. Explain your intentions.

As written: ssh'ing to a hostname (which is interactive, BTW)... piping the output to grep to capture a pattern... then /home/ is tacked on for some reason.
