verbose remote ssh (with echo)

January 20 2012 : posted under linux bash ssh sysadmin

I usually manage website deployment with bash scripts that run remote commands on the servers

In order that I can see what is going on and debug any errors verbose output is useful.

Running “bash -ex” causes each line to be output as it progresses and halt on any error so that you don’t miss it.

within the remote command “set -x” cause bash to echo all commands

#!/bin/bash -ex
ssh -T user@server << EOF
set -x
echo foo > /dev/null
EOF
