====== Configuration of some software ======
===== Linux =====

==== Your own locale ====

Maybe you don't like any predefined locale ; it was my case.

[[http://crteknologies.fr/wiki/lib/exe/fetch.php?media=linux:en_fr_euro.txt|Here]] you can find a "en_FR@euro" locale that I have defined :

  * English messages (because french messages are often strangely translated, and there is less information on the internet)
  * "yyyy/mm/dd hh:mm:ss" date format, because it is logical, and alphanumerical sort is date sort !
  * "." as decimal separator, because even French people do not write "," with a keyboard ...
  * " " (space) as thousands separator, because it is the French standard, and not so bad
  * French monetary (except decimal and thousands separators)
  * French for other features (telephone, address, measurement etc)

Rename the file to "en_FR@euro", and copy it in ''/usr/share/i18n/locales'' (you will find there all other locales, and you can look at it to make your own locale).

Add "en_FR@euro ISO-8859-15" (or UTF8) to ''/etc/locale.gen'', and run ''locale-gen''.

Now you can use the ''en_FR@euro.ISO-8859-15'' locale by exporting LC_ALL environment variable in your bashrc or zshrc or zshenv file, or even in ''/etc/env.d/02locale'' to set it for all users.

===== ZSH =====
==== Config files ====

As for all shells, there are several configuration files, loaded in the order :
<code>
.zshenv    --> always loaded, first
.zprofile  --> loaded if login shell
.zshrc     --> loaded if interactive shell
.zlogin    --> loaded when a user logins
.zlogout   --> loaded when a user logouts
</code>



==== Prompt ====

A nice prompt which prints only the two first and two last folder names of the current path (instead of the whole path or only the last folder) :

<code bash>
if [ "`id -u`" -eq 0 ]; then
# root prompt : blue
  export PS1="%{^[[33;39;1m%}%T%{^[[0m%} %{^[[33;34;1m%}%n%{^[[0m^[[33;34;1m%}@%{^[[33;39;1m%}%m %{^[[33;34;1m%}%(5~|%-2~..%2~|%~)%{^[[0m^[[33;34;1m%}%#%{^[[0m%} "
else
# user prompt : red
  export PS1="%{^[[33;39;1m%}%T%{^[[0m%} %{^[[33;31;1m%}%n%{^[[0m^[[33;31;1m%}@%{^[[33;39;1m%}%m %{^[[33;31;1m%}%(5~|%-2~..%2~|%~)%{^[[0m^[[33;31;1m%}%#%{^[[0m%} "
fi
</code>

It gives something like :
<code>
17:59 cyril@cyrilr /mnt/fat..5_Archi/annales%
</code>

==== Use the directory stack ====

Zsh permits to use the directory stack very easily, in ''zshrc'' :
<code bash>
alias d='popd'            # simple alias
setopt auto_pushd         # auto pushd with cd
setopt pushd_ignore_dups  # ignore double names of the same directory
setopt pushd_silent       # don't print the directory when popd or pushd
</code>

Then you can type ''d'' as many times you want to move back all ''cd'' you've done.

==== History size ====

It is always painful to lose what you have typed in your shell 20 lines above. You can tune it in ''zshrc'' :

<code>
export HISTORY=500
export HISTSIZE=500
export SAVEHIST=500
</code>


==== Key bindings ====

In order to use //navigation// keys, still in ''zshrc'' :

<code>
bindkey '^A'    beginning-of-line       # Home
bindkey '^E'    end-of-line             # End
bindkey '^D'    delete-char             # Del
bindkey '^[[3~' delete-char             # Del
bindkey '^[[2~' overwrite-mode          # Insert
bindkey '^[[5~' history-search-backward # PgUp
bindkey '^[[6~' history-search-forward  # PgDn

bindkey '\e[7~' beginning-of-line       # Home mrxvt
bindkey '\e[8~' end-of-line             # End mrxvt

bindkey '^[[1~' beginning-of-line       # Home rxvt
bindkey '^[[4~' end-of-line             # End rxvt

bindkey '^[[H'  beginning-of-line       # Home xterm
bindkey '^[[F'  end-of-line             # End xterm
</code>




==== Aliases ====

Still in ''zshrc'' :

<code bash>
### ls
alias ll='ls -l'
alias la='ls -a'
alias lla='ls -la'

### misc
alias c='clear'
alias less='less --quiet'
alias s='cd ..'
alias d='popd'

### df & du
alias df='df --human-readable'

# sorted du in one pass
alias du='du -a -x --max-depth=1 --human-readable > /mnt/ram/dunosort ;
 cat /mnt/ram/dunosort | grep -v -E "^[0123456789\.]+[KMG]\>" | sort -n > /mnt/ram/dusort ;
 cat /mnt/ram/dunosort | grep -E "^[0123456789\.]+[K]\>" | sort -n >> /mnt/ram/dusort ;
 cat /mnt/ram/dunosort | grep -E "^[0123456789\.]+[M]\>" | sort -n >> /mnt/ram/dusort ;
 cat /mnt/ram/dunosort | grep -E "^[0123456789\.]+[G]\>" | sort -n >> /mnt/ram/dusort ;
 cat /mnt/ram/dusort'

# sorted du in two pass
#alias du='du -a -x --max-depth=1 -b > /mnt/ram/duab.list; 
# du -a -x --max-depth=1 --human-readable > /mnt/ram/dua.list;  
# paste /mnt/ram/duab.list /mnt/ram/dua.list | sort -n | cut --fields=3,4'
</code>


===== MRXVT =====
==== History size ====

It is always painful to lose what you have typed in your shell 20 lines above. You can tune it in ''mrxvtrc'' :

<code>
mrxvt.saveLines:        10000
</code>

==== Appearence ====

<code>
mrxvt.showMenu:         False
mrxvt.background:       black
mrxvt.foreground:       white
mrxvt.scrollbarStyle:   plain
mrxvt.itabBackground:   grey
mrxvt.scrollColor:      white
mrxvt.troughColor:      grey
mrxvt.tabBackground:    white
</code>

==== Shortcuts ====

<code>
Mrxvt.macro.Shift+Left: GotoTab -1
Mrxvt.macro.Shift+Right:   GotoTab +1
Mrxvt.macro.Primary+Shift+Return:       Esc \ec
Mrxvt.macro.Ctrl+t:   NewTab
Mrxvt.macro.Ctrl+Shift+w:  Close 0
</code>

==== Other tunings ====

<code>
mrxvt.syncTabTitle:     False
mrxvt.syncTabIcon:      False
</code>
