How to log drush commands

Here's a way I came up with for logging drush commands. This might be useful for troubleshooting server slowness.

Add the following block of code to the start of the drush command:

# Rangi: Log all drush commands
LOG_STR=`date --rfc-3339=seconds`
LOG_STR="$LOG_STR drush"
PARAMS=""
for a in ${BASH_ARGV[*]} ; do
  PARAMS="$a $PARAMS"
done
LOG_STR="$LOG_STR $PARAMS (`whoami`)"
echo $LOG_STR >>/var/log/drush

This will add lines like this to /var/log/drush:

  • Enable mod_rewrite for Apache
    # a2enmod rewrite
  • Add AllowOverride within the default website configuration
    # vi /etc/apache2/sites-available/000-default.conf
