# Script to remove commands from an AOF. Writes trimmed down AOF
# to standard out. Progress report is written to standard error.
#
# Usage: redis-trim-aof.rb <appendonly.aof> [regexp ...]
# Example: redis-trim.aof.rb myaof.aof ^user:\\d+ > newaof.aof
#
# Note: make sure to provide enough escape characters for special
# characters inside the regexp (because a regular shell also does
# escaping of characters).
