taily

Taily tails teh logz. Now with colors!

What does it do?

It takes all files set in ~/.taily.json and tails them. As soon as any file updates, it shows the output in terminal for you. In single terminal. Not 50.

Installation

Locally

npm install taily

or Globally

npm install taily -g

Usage

taily [options]

Options:

-h, --help                output usage information
-V, --version             output the version number
-g, --grep [regex]        Grep the results of the output. Accepts multiple arguments sepparated by comma,
 						  for example, "foo|baz,bar" will match all lines containing (foo OR baz) AND bar.
-b, --backlog             Output ALL lines, and continue with tailing. Useful with -g.
-s, --server [host:port]  Run pretty web ui
--init                    Create blank .taily.json.dist in $HOME
-e, --edit                Launch $EDITOR to edit .taily.json.dist

Configuration

In your home, create file called .taily.json. In that file put something like this:

{
    "files": {
        "syslog": {
            "file": "/var/log/syslog",
            "color": "blue",
            "filters": [],
            "lineSeparator": "\n"
        }
    },
    "server": {
        "host": "127.0.0.1",
        "port": 9800,
        "preserve": 100
    }
}

File paths

File paths can be ordinary paths, like /var/log/syslog and can also be glob's, like /var/log/*. In later case Taily will append basename of the file to the entry key in output, and it will look something like this:

syslog>Xorg.1.log: [151362.142] X Protocol Version 11, Revision 0

Allowed colors:

black, red, green, yellow, blue, magenta, cyan, white

Filters

Filters are OR combined conditions to filter the output of a log. For example, you can set this to ["foo","bar"] to only see line containing foo OR bar.

Web ui

Web ui provides simple output of taily via web. Bear in mind, there is no authentication or anything of the kind. If you want to run this as a daemon, it will be best if you put it behind, for example, Nginx proxy and/or firewall. Security folks will, of course, adore this.

P.S.

filters and lineSeparator is optional.
