man bro-cut (1): parse bro logs

SYNOPSIS

bro-cut [options] [<columns>]

DESCRIPTION

Extracts the given columns from an ASCII Bro log on standard input. If no columns are given, all are selected. By default, bro-cut does not include format header blocks into the output.

OPTIONS

-c: Include the first format header block into the output.
-C: Include all format header blocks into the output.
-d: Convert time values into human-readable format (needs gawk).
-D <fmt> Like -d, but specify format for time (see strftime(3) for syntax).
-F <ofs> Sets a different output field separator.
-n: Print all fields *except* those specified.
-u: Like -d, but print timestamps in UTC instead of local time (needs gawk).
-U <fmt> Like -D, but print timestamps in UTC instead of local time (needs gawk).

ENVIRONMENT

BRO_CUT_TIMEFMT: For the time conversion, the format string can also be specified by setting an environment variable $BRO_CUT_TIMEFMT
