在没有sudo和root权限的机器上配置应用

basic idea: 全部符号链接到 ~/bin/

ls -s ~/bin/app /path/to/app
1

原因: 环境变量是易于配置的.

bash_profile && bashrc

PATH=$PATH:~/bin/

A shell can be interactive or non-interactive.
An interactive shell can be either login or non-login shell.

• A login shell is invoked when a user login to the terminal either remotely via ssh or locally, or when Bash is launched with the --login option.
• An interactive non-login shell is invoked from the login shell, such as when typing bash in the shell prompt or when opening a new Gnome terminal tab.

.bash_profile is read and executed when Bash is invoked as an interactive login shell, while .bashrc is executed for an interactive non-login shell.
Use .bash_profile to run commands that should run only once, such as customizing the $PATH environment variable.

以上是比较规范的做法, 实际上可以

# .bash_profile
source ~/.bashrc
1
2

离线配置 oh-my-zsh neovim

ohmyzsh zsh-autosuggestions zsh-syntax-highlighting 获取

github 下载 master, 即

• ohmyzsh-master.zip
• zsh-autosuggestions-master.zip
• zsh-syntax-highlighting-master.zip

ohmyzsh 离线安装

修改 $ZSH/tools/install.sh

1. 删去 git clone
2. 删去 if [ -d “$ZSH” ]; then 判断

进一步配置 .zshrc

提示: 无unicode的ohmyzsh主题: ys

因为没有chsh的权限 在 .bashrc 末尾添加

• echo ‘\033[91minto zsh\033[0m’
• zsh

zsh-autosuggestions zsh-syntax-highlighting 离线安装

直接解压到 $ZSH/custom/plugin

离线安装 neovim

github 下载 release (linux x86_64 .tar.gz), 直接解压获取二进制, 符号链接到 ~/bin/nvim

alias结束战斗

• alias vim=“nvim”
• alias vi=“nvim”
• alias ipy=“python -m IPython” # alias ipy2=“python -m IPython”

感谢

shell无疑是无拘无束的

只要我们有稳定的 scripts/binary

就能仅通过shell通过配置让他们一键运行

python2指南

python3的重要改进

1. 抛出异常必须是BaseException的子类
2. map filter 必须是迭代器
3. print repr 必须是函数调用
4. unicode天然支持 无需指明u"…"
5. 整数类型 && 整数除法语义
6. __init__.py

python 重要命令行参数: -m

示例

python2.7 -m IPython

虽然不够丰富,但是!cmd %magic等基本feature可以使用
