home-manager

注意 jeakin 是我的用户名,需要替换 home 脚本内的

#自己的用户名和路径
home.username = "jeakin";
home.homeDirectory = "/Users/jeakin";

# 初次使用
nix run nixpkgs#home-manager switch -- --flake .#jeakin
# 安装完 home-manager 以后
home-manager switch --flake .#jeakin

1. Run home-manager generations to determine which generation you wish to rollback to:

   $ home-manager generations
   2018-01-04 11:56 : id 765 -> /nix/store/kahm1rxk77mnvd2l8pfvd4jkkffk5ijk-home-manager-generation
   2018-01-03 10:29 : id 764 -> /nix/store/2wsmsliqr5yynqkdyjzb1y57pr5q2lsj-home-manager-generation
   2018-01-01 12:21 : id 763 -> /nix/store/mv960kl9chn2lal5q8lnqdp1ygxngcd1-home-manager-generation
   2017-12-29 21:03 : id 762 -> /nix/store/6c0k1r03fxckql4vgqcn9ccb616ynb94-home-manager-generation
   2017-12-25 18:51 : id 761 -> /nix/store/czc5y6vi1rvnkfv83cs3rn84jarcgsgh-home-manager-generation
   …

2. Copy the Nix store path of the generation you chose, e.g.,

   /nix/store/mv960kl9chn2lal5q8lnqdp1ygxngcd1-home-manager-generation

   for generation 763.

3. Run the activate script inside the copied store path:

   $ /nix/store/mv960kl9chn2lal5q8lnqdp1ygxngcd1-home-manager-generation/activate
   Starting home manager activation
   

4. 清理 generations

   home-manager expire-generations '-30 minutes'
   nix-collect-garbage

# 包管理
nix-env -qa <name>  # 查询包
nix-env -i <name>   # 安装包
nix-env -e <name>   # 移除包
nix-env -u <name>   # 升级包
nix-env -u          # 升级所有包

# 用户profile版本管理
nix-env --list-generations     # 列出所有版本
nix-env --switch-generation x  # 选择某个版本
nix-env --rollback             # 回退倒上一个版本

# 垃圾回收
nix-env --delete-generations [+5|14d|old]  # 删除旧profile版本
nix-store --gc          # 垃圾回收，引用计数源头在 /nix/var/nix/gcroots
nix-collect-garbage -d  # 删除所有旧版本并执行一次垃圾回收
