-When running Drush in a terminal, the number of columns will be automatically determined by Drush by way of the tput command, which queries the active terminal to determine what the width of the screen is. When running Drush from cron, there will not be any terminal set, and the call to tput will produce an error message. Spurrious error messages are undesirable, as cron is often configured to send email whenever any output is produced, so it is important to make an effort to insure that successful runs of cron complete with no output.
