My Dotfiles

These are my dot files. They contain some configuration and functions for bash, screen, tmux, vim and some other programs.

Installation

First of all you have to clone the git repository. Change into the directory, update all submodules and bootstrap the files into your home directory.

git clone https://github.com/HaraldWeber/dotfiles.git 
cd dotfiles
git submodule update --init --recursive
./bootstrap.sh

Updating

If you have already cloned the repository you can just run the update.sh to update all submodules and bootstrap the files.

cd dotfiles
./update.sh

Commands

I have added some handy commands.

calc

calc is a calculator for the command line. It uses bc for the calculation. If you use some special characters you have to use apostrophes.

Examples:

$ calc 1+2
3
$ calc '(1+3)*2'
8

cpuq netq ioq

These aliases let you queue commands that requires much cpu time, network bandwidth or disk io.

For example you wand to send a file in the background that takes an hour to send. After a minute you want to send more files. If you send them parallel it would take ages to complete the first file. To avoid this you can use the alias netq_.

$ netq scp some.file remote:/tmp/
0
$ netq scp other.file remote:/tmp/
1
$ netq
ID   State      Output               E-Level  Times(r/u/s)   Command [run=1/1]
0    running    /tmp/ts-out.cEwzhE                           scp some.file remote:/tmp/
1    queued     (file)                                       scp other.file remote:/tmp/

This will run the first command immediately and queues the second. Run netq to show the queue.
For more information run netq -h.

install-key

This program installs your public ssh key to the specified server.

$ install-key <remote_host> [ssh_port] [public_key_file]

formatJSON

This alias formats json syntax using pythons json.tool. Python is required for this alias.

$ cat unformatted.json | formatJSON > formatted.json
$ curl http://json.com/unformatted.json | formatJSON
{
 jsontext: "Some formatted json"
}

open

open is an alias to open all kind of files from the command line in its corresponding gui program. Its behavior is like the open command on OSX.

open some.pdf

This will open the pdf in your standard pdf reader.

tmux

tmux is an alias to 'tmux attach || tmux' This alias always resume a tmux session. If there is no session just start tmux.

tmux-remote

This is a script to easily create a shared tmux session.
One user creates a sessions with the command tmux_remote and the other user executes tmux_remote attach.
The user who wants to attach a session gets a menu with open tmux sessions to choose from.

tunnel

Opens a ssh tunnel and executes the optional command. If no command is given the program waits until CTRL + d is pressed.

$ tunnel <port> <remote_host> [command]
$ tunnel <sourcePort> <destinationPort> <remote host> [command]

bat

bat is an alias to show some battery infos

$ bat 
    state:               discharging
    time to empty:       2,9 hours

backup

A script to wrap duplicity. Make backups simple. Execute backup to show the usage.

$ backup

Directory Structure

Each program has its own directory. Some files are symlinked to to the home directory (e.g. .bashrc).

.bash

This directory contains all files for the bash.

• .bashrc just calls .bash_profile
• .bash_profile first sets a few options for the bash.
  Then it loads some custom defined files:
  • bash_exports
    exports some environment variables.
  • bash_path
    builds up the PATH variable.
  • bash_aliases
    sets up some aliases.
  • bash_completion
    loads custom completion functions.
  • bash_prompt
    builds up the bash prompt.

Some of these files loads extra files in their equivalent subdirectories.

For example bash_aliases loads all files in aliases.
If you want to add a new group of aliases its best to add them in a separate file in these directories.

For customizations the filenames should end with .custom.bash. Then git will ignore these files.

The .bash/bin directory includes some executable scripts. This directory is added to the PATH variable in the bash_path file.

.screen

Contains the configuration for screen.

.tmux

For tmux.

.vim

Contains the configuration and plugins for vim. .vimrc is symlinked from the home directory.

<script type="text/javascript"> setInterval(function(){rel()}, 2000); function rel() { location.reload(true); } </script>
