SYNOPSIS ^

For reducing the amount of typing needed to access frequently-needed server locations. e.g. if you often need to get to the /var/log directory of the server at example.com you should be able to reach it as simply as

    g2 ex log

instead of having to go the normal route of

    ssh example.com
    cd /var/log

Requires config file in either/both of:

    /etc/g2rc   ~/.g2rc

In the format:

    [hosts]
    localhost   = 127.0.0.1
    first       = firstserver
    second      = secondserver
    szzzzz      = szzzzzserver
    [commands]
    log = 'cd /var/log/{{mod}} && bash'
    top = 'top'
    [first_commands]
    top = 'htop'

Usage:

    g2 l            => ssh 127.0.0.1
    g2 l log        => ssh 127.0.0.1 -t 'cd /var/log/ && bash'
    g2 l log/syslog => ssh 127.0.0.1 -t 'cd /var/log/syslog && bash'
    g2 l top        => ssh 127.0.0.1 -t 'top'
    g2 f top        => ssh firstserver -t 'htop'
    g2 s            => ssh secondserver
    g2 sz           => ssh szzzzzserver

CONVENTIONS ^

The hostname passed in at the command line can be the shortest possible string needed to correctly identify the correct server; commands are optional but must be supplied in full.

When a supplied hostname is ambiguous, such as 's' in the above examples, g2 will always use the first version according to Perl's sorting logic.

When anything is specified in both the /etc and the user's own config file, the user's version will always be used.

An optional modifier can be supplied to any command by putting a placeholder, '{{mod}}', into the config file's command string; then adding the modifier to the command string on execution, separated by a '/' - see the 'syslog' example above. The strings {{nick}} and {{host}} also exist, to populate the command with your own nickname for the server and its actual hostname.

Server-specific commands may be specified, which can either be unique, or with the same name as a generic command, which it will over-ride.
