goto

Change to a directory and list its content using an alias. Aliases are defined as environment variables, hence auto-completed by default.

What's the point? Sometimes projects with complex directory structure have key places from which you run build/tests/you name it. It's very convenient to be able to jump there from any point of the tree.

Why not cd instead? You can always use cd over goto with defined aliases (remember it's only a variable). The goto's added value is its ability to manage the aliases. If you are like me, you tend to forget, a lot, so goto has a command that reminds you what aliases you already have.

Installation

# Clone the repository
$ git clone https://github.com/antagon/goto

# Copy the script in your home directory
$ cp goto/goto.sh ~/.goto

# Put bootstrap code in your .bashrc
$ cat goto/setup.sh >> ~/.bashrc

# Reload .bashrc
$ source ~/.bashrc

Usage

Add directory aliases

$ goto_edit
git="~/git"
git_goto="$git/antagon/goto"
desktop="~/Desktop"
downloads="~/Downloads"
images="~/Images"

The command will open default EDITOR (as defined in environment variable $EDITOR) and reloads the file after it's closed. Aliases are defined as environment variables.

List existing aliases

$ goto_list
$desktop         ~/Desktop
$downloads       ~/Downloads
$git             ~/git
$git_goto        ~/git/antagon/goto
$images          ~/Images

The command lists defined directory aliases.

Go to directory

$ goto $desktop
total 0
-rw-r--r-- 1 user user 0 Jun  6 13:59 readme.txt

The command will switch to ~/Desktop directory and list its content.

Reload directory aliases

$ goto_reload

The command will reload alias file. This is useful when you have edited the file without use of goto_edit.

Shorthand commands

In setup.sh there are default aliases for your shell that you may find useful when using goto. If you do not want to use them, either delete them from setup.sh, or your ~/.bashrc.

A shorthand for goto.

$ g $desktop
total 0
-rw-r--r-- 1 user user 0 Jun  6 13:59 readme.txt

A shorthand for goto_list.

$ gl
$desktop         ~/Desktop
$downloads       ~/Downloads
$git             ~/git
$git_goto        ~/git/antagon/goto
$images          ~/Images

$alias/path support

Since variables ($alias) is expanded to its value, before being passed to goto, it's perfectly fine to use:

$ g /etc/ssh

# Switch to home dir
$ g ~

# Combine $alias with arbitrary strings (switch to ~/git/dockerfiles)
$ g $git/dockerfiles
