# remtail

tail out log files from multiple remote hosts

![Image of example command](/remtail.png)

#  [![NPM version][npm-image]][npm-url][![Build Status](https://travis-ci.org/NickCarneiro/remtail.svg)](https://travis-ci.org/NickCarneiro/remtail)

# install!

```

npm install -g remtail

```

# basic usage

Connect to as many hosts as you want.

```

remtail trillworks.com:/var/log/nginx/access.log okpedro.com:/var/log/apache2/other_vhosts_access.log

```

Specify multiple files on the same host by repeating the hostname.

```

remtail trillworks.com:/var/log/nginx/access.log trillworks.com:/var/log/nginx/error.log

```

grep-like functionality with highlighting.

Only print lines containing "Comment", with "Comment" shown in red.

```

  remtail --grep "Comment" trillworks.com:/var/log/apache2/other_vhosts_access.log

```

For case insensitive search, use --grepi.

```

remtail --grepi "Comment" trillworks.com:/var/log/apache2/other_vhosts_access.log

```

You have full support for JavaScript regular expressions, so you can search for multiple strings like this:

```

remtail --grepi "GET|POST" trillworks.com:/var/log/apache2/other_vhosts_access.log

```

# advanced usage

To avoid typing in passwords for every host,

[copy your public key](http://askubuntu.com/questions/4830/easiest-way-to-copy-ssh-keys-to-another-machine)

to the remote servers. Then add entries in your ssh config. (~/.ssh/config). Here is the format:

    Host trillworks

        HostName trillworks.com

        User burt

        IdentityFile ~/.ssh/id_rsa

Specify an alternate ssh config with -s.

If you want to live dangerously, you can throw your passwords in a json credentials file (~/.remtail.json).

*WARNING: This is deprecated and will be removed in version 1.0.*

        "user": "woody",

    ]

Specify an alternate credentials file path with -c.
