# Script adapted from suggestions on https://unix.stackexchange.com/a/527004/1925

|
# Passed a ledger file, this will:
|
|
# 1. Sort accretion postings before deductions
|
|
# 2. Sort postings by account alphabetically
|
|
# 3. Merge 1 set of postings with the same account and direction by clearing
|
|
# the amount field. Note all posting meta data must also match to merge.
|
|
#
|
|
# Suggested usage:
|
|
# $ sortandmergepostings journal.ledger | hledger -f - print -x
|
|
#
|
|
# Given that each run will only merge and recalculate amounts on one account per
|
|
# transaction it may need to be run multiple times to fully normalize a ledger.
