Z Shell

Z Shell

ZSH és un shell dissenyat per a un ús interactiu, tot i que també és un llenguatge de script molt potent. Moltes de les característiques útils de bash, ksh i tcsh es van incorporar a zsh; es van afegir moltes funcions originals.

Una de les característiques que té ZSH és que ens podem loguejar en entrar.

Per saber si estem loguejats caldrà escriure el següent codi:

    if [[ -o login ]]; then
      print yes
    else
      print no
    fi

Si la resposta és no, doncs no estarem loguejats.

Fitxers de configuració:

/etc/zshenv

Corre sempre per cada zsh.

~/.zshenv

Normalment s’executa per cada zsh.

/etc/zprofile

Executar per iniciar la sessió.

~/.zprofile

Executar per iniciar la sessió.

/etc/zshrc

Executar per iniciar la interactivitat del shell.

~/.zshrc

Executar per iniciar la interactivitat del shell.

/etc/zlogin

Executar per obtenir shells d’inici de sessió.

~/.zlogin

Executar per obtenir shells d’inici de sessió.

Per què és bo ZSH:

  • Per editar en línia de comandaments
  • Globalment es extremadament potent
  • Per escriure múltiples redireccions
  • Per utilitzar moltes opcions
  • Per expandir els directoris (=foo -> /usr/bin/foo)
  • Per adaptar missatges
  • Per cridar els directoris
  • Per operar de forma comprensiva
  • Per manipular arrays
  • Per associar arrays (clau-valor hashes)
  • Per corregir errors de sintaxi

A l’arxiu .zshrc afegirem aquest codi:


# Path to your oh-my-zsh installation.
export ZSH="/home/alfons/.oh-my-zsh"

# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
ZSH_THEME="robbyrussell"

# Set list of themes to pick from when loading at random
# Setting this variable when ZSH_THEME=random will cause zsh to load
# a theme from this variable instead of looking in ~/.oh-my-zsh/themes/
# If set to an empty array, this variable will have no effect.
# ZSH_THEME_RANDOM_CANDIDATES=( "robbyrussell" "agnoster" )

# Uncomment the following line to use case-sensitive completion.
# CASE_SENSITIVE="true"

# Uncomment the following line to use hyphen-insensitive completion.
# Case-sensitive completion must be off. _ and - will be interchangeable.
# HYPHEN_INSENSITIVE="true"

# Uncomment the following line to disable bi-weekly auto-update checks.
# DISABLE_AUTO_UPDATE="true"

# Uncomment the following line to automatically update without prompting.
# DISABLE_UPDATE_PROMPT="true"

# Uncomment the following line to change how often to auto-update (in days).
# export UPDATE_ZSH_DAYS=13

# Uncomment the following line if pasting URLs and other text is messed up.
# DISABLE_MAGIC_FUNCTIONS=true

# Uncomment the following line to disable colors in ls.
# DISABLE_LS_COLORS="true"

# Uncomment the following line to disable auto-setting terminal title.
# DISABLE_AUTO_TITLE="true"

# Uncomment the following line to enable command auto-correction.
# ENABLE_CORRECTION="true"

# Uncomment the following line to display red dots whilst waiting for completion.
# COMPLETION_WAITING_DOTS="true"

# Uncomment the following line if you want to disable marking untracked files
# under VCS as dirty. This makes repository status check for large repositories
# much, much faster.
# DISABLE_UNTRACKED_FILES_DIRTY="true"

# Uncomment the following line if you want to change the command execution time
# stamp shown in the history command output.
# You can set one of the optional three formats:
# "mm/dd/yyyy"|"dd.mm.yyyy"|"yyyy-mm-dd"
# or set a custom format using the strftime function format specifications,
# see 'man strftime' for details.
# HIST_STAMPS="mm/dd/yyyy"

# Would you like to use another custom folder than $ZSH/custom?
# ZSH_CUSTOM=/path/to/new-custom-folder

# Which plugins would you like to load?
# Standard plugins can be found in ~/.oh-my-zsh/plugins/*
# Custom plugins may be added to ~/.oh-my-zsh/custom/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
plugins=(git)
