# brethil's dotfiles #
|
||||||
|
|
||||||
|
|
||||||

## Description ##
|
||||||
|
|
||||||
|
1. brethil_dotfile.sh: main file sourced by ~/.bash_profile
|
||||||
|
2. aliases.sh: contains alias definitions (sources ~/.bash_aliases)
|
||||||
|
3. functions.sh: contains function definitions (sources ~/.bash_functions)
|
||||||
|
4. colors.sh: contains color definitions
|
||||||
|
5. install.sh: run to install brethil's dotfiles
|
||||||
|
|
||||||
|
## Installation ##
|
||||||
|
Copy the dotfiles folder to the location where you want to keep it and then run install:
|
||||||
|
|
||||||
|
$ cd dotfiles && bash install.sh
|
||||||
|
|
||||||
|
Installs oh-my-zsh and sources aliases.sh, functions.sh and colors.sh, as well as installing
|
||||||
|
a a few utilities (see `install.sh`)
|
||||||
|
|
||||||
|
### Installed programs ###
|
||||||
|
|
||||||
|
0. oh-my-zsh (zsh config)
|
||||||
|
1. byobu (wrapper/config for tmux, a screen multiplexer)
|
||||||
|
2. grc (generic colourizer, colours output of any command)
|
||||||
|
3. bmon (bandwidth monitor, shows graphs for bandwith usage)
|
||||||
|
3. rmate remote for Textmate (can be called with `mate`/`rmate`)
|
||||||
|
|
||||||
|
### Available Commands ###
|
||||||
|
|
||||||
|
1. Quickly edit/reload profile (`esource`/`resource`)
|
||||||
|
2. `ramdisk` (only on OSX) create a RAM disk. Default size: 1GB
|
||||||
|
` ramdisk 4`
|
||||||
|
creates a 4GB RAM disk
|
||||||
|
3. `color` to print colored text (see 3. in the Misc section):
|
||||||
|
color red "This will be printed in red"
|
||||||
|
4. `mecp` to copy files back to the machine from wich you are ssh-ing.
|
||||||
|
For this to work an ssh tunnel with Remoteforward is needed:
|
||||||
|
ssh -R 22:localhost:2222 YOURHOSTNAMEHERE
|
||||||
|
or specify this in ~/.ssh/config:
|
||||||
|
Host YOURHOSTNAMEHERE
|
||||||
|
Remoteforward 2222 localhost:22
|
||||||
|
You might have to manually edit the username in the mecp definition in functions.sh if this is
|
||||||
|
different between the two machines. mecp copies by default on the local machine on ~/Desktop/
|
||||||
|
5. Many more. Type "list_functions" to list defined functions and a small description
|
||||||
|
|
||||||
|
|
||||||
|
### Files/Folders ###
|
||||||
|
1. `~/bin`, `~/python`, `~/projects` folders
|
||||||
|
2. ssh config (`~/.ssh/config`):
|
||||||
|
* Create ssh keys if not defined already
|
||||||
|
* Keep connections alive by increasing timeout time
|
||||||
|
* Include multiplexer to allow quick multiple connections to the same host
|
||||||
|
* (Optional: Compression, this should allow more responsive shells with slow connections,
|
||||||
|
but will slow things down when copying large files. My suggestion is to have compression enabled
|
||||||
|
on a by-host basis in `~/.ssh/config`)
|
||||||
|
3. brethil.zsh-theme, theme for oh-my-zsh, installed in ~/.oh-my-zsh/themes/
|
||||||
|
4. ~/.dotfiles_functions, ~/.dotfiles_aliases are sourced by this dotfiles, allowing for custom functions/aliases
|
||||||
|
5. useful_commands contains a list of useful commands (the first rule of the tautology club...)
|
||||||
|
### Misc ###
|
||||||
|
|
||||||
|
1. Colored output for `ls`/`grep`/`man`
|
||||||
|
2. Easy names for ANSI color escapes (Black, Red, Green, Yellow, Blue, Cyan, Purple, White, CLEAR),
|
||||||
|
for example:
|
||||||
|
`echo -e "${Green}This text will be green${CLEAR}"`
|
||||||
|
will result in green text. Use `$CLEAR` to clear previous escale sequences add B before the variable
|
||||||
|
name to use **bold** and U to underline (examples: $BRed, $UBlack for bold red and underlined black)
