# lltsv
A CLI tool to list specified keys of LTSV (Labeled Tab Separated Values)
# Description
`lltsv` is a command line tool written in golang to list specified keys of LTSV (Labeled Tab Separated Values) text.
Example 1:
```bash
$ echo "foo:aaa\tbar:bbb\tbaz:ccc" | 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.
Example 2:
```bash
$ echo "foo:aaa\tbar:bbb\tbaz:ccc" | lltsv -k foo,bar -K
aaa bbb
```
Eliminate labels with `-K` option.
Example 3:
```bash
$ lltsv -k foo,bar -K file*.log
```
Specify input files as arguments.
**How Useful?**
LTSV format is not `awk` friendly (I think), but `lltsv` can help it:
```bash
$ echo -e "time:2014-08-13T14:10:10Z\tstatus:200\ntime:2014-08-13T14:10:12Z\tstatus:500" \
| lltsv -k time,status -K | awk '$2 == 500'
2014-08-13T14:10:12Z 500
```
Useful!
## Usage
```
$ lltsv -h
