Full Discussion: Output of ssh command from localhost - direct to local file.
Top Forums UNIX for Dummies Questions & Answers Output of ssh command from localhost - direct to local file. Post 302897384 by bakunin on Monday 14th of April 2014 01:02:29 AM

Omit the remote redirection and use a local one, then use a loop to go through the list of remote hosts. Here is a sketch:

Code:
CMD="ps | grep http | wc -l"
for host in list_of_remote_hosts ; do
     ssh -q "$host" "bash -s $CMD" >> /path/to/logfile
done

I hope this helps.

trace-cmd-listen

TRACE-CMD-LISTEN(1)													       TRACE-CMD-LISTEN(1)

NAME

       trace-cmd-listen - listen for incoming connection to record tracing.

SYNOPSIS

       trace-cmd listen -p port [OPTIONS]

DESCRIPTION

       The trace-cmd(1) listen sets up a port to listen to waiting for connections from other hosts that run trace-cmd-record(1) with the -N
       option. When a connection is made, and the remote host sends data, it will create a file called trace.HOST:PORT.dat. Where HOST is the name
       of the remote host, and PORT is the port that the remote host used to connect with.

OPTIONS

       -p port
	   This option will specify the port to listen to.

       -D
	   This options causes trace-cmd listen to go into a daemon mode and run in the background.

       -d dir
	   This option specifies a directory to write the data files into.

       -o filename
	   This option overrides the default trace in the trace.HOST:PORT.dat that is created when a remote host connects.

       -l filename
	   This option writes the output messages to a log file instead of standard output.

SEE ALSO

       trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-reset(1),
