The following script makes it a no-brainer:
% NEXT_YEAR=2015; ag -l 'Copyright.*Wiegley' \
| xargs sed -i '' -e "s/\(Copyright.*\)-20[0-9]\{2\}/\1-${NEXT_YEAR}/"
The --group-by option allows for most reports to be split up into
sections based on the varying value of EXPR. For example, to see
register subtotals by payee, use:
ledger reg --group-by=payee -s
This works for separated balances too:
ledger bal --group-by=payee
Another interesting possibility is seeing a register of all the accounts
affected by a related account:
ledger reg -r --group-by=payee
The option --group-title-format can be used to add a separator bar to
the group titles. The option --no-titles can be used to drop titles
altogether.
