Bash aliases

Tick the usual shortcuts, add your own, and paste the block into your configuration. The options of ls or df differ between Linux and macOS: the tool writes those of your system.

System
Your aliases

    The command is written between single quotes: $HOME or $(date) are only replaced when you use the alias.

    Good to know
    
    
    
      
    \rm, command rm
    
      
    Bypass an alias for once and run the real command.
    
      
    alias, unalias ll
    
      
    List the aliases in force; remove one until the terminal closes.
    
      
    In scripts
    
      
    Aliases only work in an interactive shell: a script never sees them. For something reusable in scripts, write a function or a small script in ~/bin.

    The block is written in your browser, by the scripts listed below. Nothing you type leaves this page.
    
    
    
      
    Enforced by your browser
    
      
    This page's Content Security Policy allows a single destination, the site's audience measurement (connect-src https://stats.r-no.fr, see below), and forbids any form submission (form-action 'none'), so even a bug could not send what you type anywhere. You can read the policy at the top of the page source.
    Audience measurement
    Like every page of the site, this one counts its visit with Umami, installed on R-no’s own server (stats.r-no.fr). It receives the address of the page, without parameters or anchor, the site you came from (its domain only), your browser, system, language and screen size, and the country, region and city deduced from your IP address, which is not kept. It never receives what you type, nor the result of the tool. No cookie, nothing stored in your browser; if your browser asks not to be tracked (Do Not Track), nothing is measured. The data is erased after 25 months.
    • /commun/mesure.js: the filter applied before each sending, written for R-no Toolbox. 1.4 kB

    • https://stats.r-no.fr/m.js: Umami’s tracker, open source (MIT), served by the measurement server. Its fingerprint is not shown here: it changes with each version of Umami, and you cannot check from your browser that it is the published code. For that part, you have to trust R-no.
    

      
    What is stored
    
      
    No cookie, and nothing in the address. What you type is never stored: it disappears when you reload or close the page. Your language is given by the address itself (/en/ or /fr/): nothing is stored to remember it. Like any website, the server records the download of the page and its files in its access logs (IP address, date and time, address requested, browser name). It never receives what you type.

    Before you paste
    
      
    This page only writes text: it runs nothing, neither here nor on your machine. What you paste into a terminal or a configuration file runs with your rights, so read it first. The code it writes downloads nothing and calls no outside service.
    

      
    How it was checked
    
      
    The whole catalogue, for Linux and for macOS, plus aliases full of quotes and $, was loaded into bash 5.2 and passes ShellCheck; alias then shows each command exactly as written.
    

      
    Check it yourself
    
      
    Download a script and compare its fingerprint with the one above:
    curl -s https://r-no.fr/bash/aliases/app.js | shasum -a 256
    

      
    Limits
    
      
    Bash only: zsh (the default shell of macOS since 2019) reads the same alias lines, but from ~/.zshrc. On macOS, “Linux only” aliases are left out (free, ip, coloured diff). The tool does not know which commands exist on your machine: an alias to a missing program simply fails when used.
