What is Tails

-** Tracking measures ** can (probably) the strongest OS --All data can be deleted after use --By default, only tor browser can be used, and torproxy is set. --The Mac address will be changed automatically at startup. --Logs and all files are deleted and initialized except for Pesistant volume data. --No root password has been set. Set on the welcome screen at login.

usb installation (Mac)

The usb for booting was created on Mac. tails --Download the img file --After adding the chrome extension, click Verify Tails --Download balenaEtcher on Mac, launch it and select the img file. If you select a USB file here, it will be written. --Start from blue screen

Persistant volume (directory where data is not deleted when the power is turned off)

Personally, I have two things that I want as soon as the development environment is initialized. --The terminal is at least easy to see. This time I made Solarized dark the default. ) --Minimum bashrc and vimrc.

Automate the minimum required settings at startup with bash

I want you to achieve the minimum level when using it as an OS, but I wrote a simple shell script because it is troublesome to set it every time.

`initial.bash`


#!/bin/bash
mkdir ~/.vim
cp ~/Persistent/vimrc ~/.vim/vimrc
cp ~/Persistent/bashrc ~/.bashrc
source ~/.bashrc
git clone https://github.com/sigurdga/gnome-terminal-colors-solarized.git
cd gnome-terminal-colors-solarized/
./install.sh

By running this shell script, I put bashrc and vimrc in the right places. bashrc

`bashrc`


# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

export HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

Impressions used

This time, I automated the minimum settings, but I felt stressed that I couldn't use it immediately after starting it. Also, updating the newly discovered bashrc and vimrc settings on the main OS is quite troublesome. It made me think again that the trade-off between privacy and convenience is difficult.

Try using [Tails], a purveyor of hackers (?), By USB booting.
