NAME
evmsort - Sorts events
SYNOPSIS
evmsort [-s sort_spec] [filename | -]
OPTIONS
-s sort_spec
The alternate sort specification. By default events are sorted into
ascending timestamp order. See the DESCRIPTION section for the syntax
of the sort_spec.
OPERANDS
filename
Reads event sources from filename. If filename is omitted, or is
specified as -, event sources are read from stdin.
DESCRIPTION
The evmsort command reads a stream of events and sorts them according to
the supplied criteria. By default events are read from stdin, and are
sorted into ascending timestamp order.
The -s flag specifies sort_spec as an alternate sort specification. The
specification is a character string of the following form:
@key_item[+|-] [ :@key_item[+|-] ]
The key_item is the name of any EVM standard data item and the @ character
is optional. The optional trailing + or - character indicates ascending
(+) or descending (-) sort. By default, items are sorted in ascending
order. Multiple items can be specified in the string by separating them
with colon characters (:). The left-most key_item in the specification is
the most significant key.
RESTRICTIONS
The evmsort command rejects attempts to output raw events to a terminal
device.
EXAMPLES
The following example retrieves all events with a priority of 300 or
greater, sorts them into descending order of priority (most urgent first)
and then ascending order of time (oldest first), and displays them:
evmget -f '[priority >= 300]' | evmsort -s "@priority-:@timestamp" |
evmshow -t "@priority @timestamp @@"
The following example yields a list of all events, sorted latest first
within name:
evmget | evmsort -s "@name:@timestamp-" |
evmshow -t "@name @timestamp @@"
EXIT VALUES
The following exit values are returned:
0 Successful completion
not 0
An error occurred
