What Others Think

You really could simplify ... there is no need for so many pipes. I don't have an exim_mainlog so can't run the command against some input but as awk can do more than 'print' you could exclude 'grep' and 'grep -v' by using awk to match the pattern, eg: awk '!/var/spool/ && /cwd/{print $2}' You could also probably avoid setting the field to 'cwd=' and the double awk by refining the expression or using 'gsub' to crop the required string.
