verbose remote ssh (with echo)

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" cuase bash to echo all commands

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

The drush script which provides comman line acceess to drupal functionality emits an error message when run as a cron job

tput: No value for $TERM and no -T specified

# If it is not exported determine and export the number of columns.
if [ -z $COLUMNS ]; then
  export COLUMNS=$(tput cols)
fi

I presume drush uses this information to calculate layout of output.

However when running as a cron job COLUMNS is not set and tput gives the above error.
