NAME

lltsv - List specified keys of LTSV (Labeled Tab Separated Values)

SYNOPSIS

lltsv [global options] command [command options] [arguments...]

lltsv [ --key value] [ -k value] [ --no-key ] [ -K ] [ --ignore-key value] [ -i value] [ --filter value] [ -f value] [ --expr value] [ -e value] [ --help ] [ -h ] [ --version ] [ -v ]

DESCRIPTION

lltsv is a command line tool to list specified keys of LTSV (Labeled Tab Separated Values) text with colorized output to a terminal. It supports to filter with some comparing operators (arithmetic expression or regular expression)

OPTIONS

--key value

keys to output (multiple keys separated by ,)

--no-key , -K

output without keys (and without color)

--ignore-key value, -i value

ignored keys to output (multiple keys separated by ,)

--filter value, -f value

filter expression to output

--expr value, -e value

evaluate value by expression to output

--help , -h

show help

--version , -v

print the version

EXAMPLES

Example1:

$ echo "foo:aaa\tbar:bbb" | lltsv -k foo,bar
foo:aaa bar:bbb

The output is colorized as default when you outputs to a terminal. The coloring is disabled if you pipe or redirect outputs.

Example2:

$ echo "foo:aaa\tbar:bbb" | lltsv -k foo,bar -K
aaa bbb

Eliminate labels with "-K" option.

Example3:

$ lltsv -k foo,bar -K file*.log

Specify input files as arguments.

Example4:

$ lltsv -k resptime,status,uri -f ’resptime > 6’ access_log
$ lltsv -k resptime,status,uri -f ’resptime > 6’ -f ’uri =˜
ˆ/foo’ access_log

Filter output with "-f" option. Available comparing operators are:

	•		>= > == < <= (arithmetic (float64))
	•		== ==* != !=* (string comparison (string))
	•		=˜ !˜ =˜* !˜* (regular expression (string))

The comparing operators terminated by * behave in case-insensitive. You can specify multiple -f options (AND condition).

Example5

$ lltsv -k resptime,upstream_resptime,diff -f ’diff = resptime - upstream_resptime’ access_log
$ lltsv -k resptime,upstream_resptime,diff_ms -e ’diff_ms =
(resptime - upstream_resptime) * 1000’ access_log

Evaluate value with "-e" option. Available operators are: + - * / (arithmetic (float64))
