 You can also install it to `/opt`:
 ```
 sudo xmake i -o /opt/goldfish --root

 For uninstallation, just:

+### Subcommands
+
+Goldfish Scheme uses subcommands for different operations:
+
+| Subcommand | Description |
+|------------|-------------|
+| `help` | Display help message |
+| `version` | Display version information |
+| `eval CODE` | Evaluate Scheme code |
+| `load FILE` | Load Scheme file and enter REPL |
+| `repl` | Enter interactive REPL mode |
+| `run TARGET` | Run main function from target |
+| `test` | Run tests |
+| `fix PATH` | Format Scheme code |
+| `FILE` | Load and evaluate Scheme file directly |
+
+### Display Help
+Without any command, it will print the help message:

---version       display version
--e              -e '(+ 1 2)'

-FILE            Load the scheme code on path and print the evaluated result

+Commands:

+  eval CODE          Evaluate Scheme code
+  load FILE          Load Scheme code from FILE, then enter REPL
+  ...
 ```
 
-### Version Option
-`--version` will print the Goldfish Scheme version and the underlying S7 Scheme version:
+### Display Version
+`version` subcommand will print the Goldfish Scheme version and the underlying S7 Scheme version:
 ```
-> bin/goldfish --version
-Goldfish Scheme 17.10.0 by LiiiLabs
-based on S7 Scheme 10.11 (2-July-2024)
+> bin/gf version
+Goldfish Scheme 17.11.30 by LiiiLabs
+based on S7 Scheme 11.5 (22-Sep-2025)
 ```
 
-### Mode Option
-`-m` helps you specify the standard libray mode.
-
-+ `default`: `-m default` is the equiv of `-m liii`
-+ `liii`: Goldfish Scheme with `(liii oop)`, `(liii base)` and `(liii error)`
-+ `scheme`: Goldfish Scheme with `(liii base)` and `(liii error)`
-+ `sicp`: S7 Scheme with `(scheme base)` and `(srfi sicp)`
-+ `r7rs`: S7 Scheme with `(scheme base)`
-+ `s7`: S7 Scheme without any extra library
-
-### Other Options
-`-e` helps you evaluate the scheme code on the fly:
+### Evaluate Code
+`eval` subcommand helps you evaluate Scheme code on the fly:
 ```
-> bin/goldfish -e "(+ 1 2)"
+> bin/gf eval "(+ 1 2)"
 3
-> bin/goldfish -e "(begin (import (srfi srfi-1)) (first (list 1 2 3)))"
+> bin/gf eval "(begin (import (srfi srfi-1)) (first (list 1 2 3)))"
 1
-> bin/goldfish -e "(begin (import (liii sys)) (display (argv)) (newline))" 1 2 3
-("bin/goldfish" "-e" "(begin (import (liii sys)) (display (argv)) (newline))" "1" "2" 3)
-#\newline
+> bin/gf eval "(begin (import (liii sys)) (display (argv)) (newline))" 1 2 3
+("bin/gf" "eval" "(begin (import (liii sys)) (display (argv)) (newline))" "1" "2" "3")
 ```
 
-`-l` helps you load the FILE:
+### Load File
+`load` subcommand helps you load a Scheme file and enter REPL:
 ```
-> bin/goldfish -l tests/demo_error.scm 
-
-;car argument, (), is nil but should be a pair
-;    (list)
-;    tests/demo_error.scm, line 1, position: 10
-; (list)
-
-> bin/goldfish -l tests/demo_no_error.scm
-> bin/goldfish -l tests/demo_argv.scm 1 2 3
-("bin/goldfish" "tests/demo_argv.scm" "1" "2" "3")
+> bin/gf load tests/goldfish/liii/base-test.scm
+; load the file and enter REPL
 ```
 
-If no options provided, it will load the FILE and print the eval result:
+### Run File Directly
+You can also load and evaluate a Scheme file directly:
+```
+> bin/gf tests/goldfish/liii/base-test.scm
+; *** checks *** : 1973 correct, 0 failed.
 ```
-> bin/goldfish  tests/demo_no_error.scm 
-tests/demo_no_error.scm => 3
-> bin/goldfish  tests/demo_error.scm 
 
-;car argument, (), is nil but should be a pair
-;    (list)
-;    tests/demo_error.scm, line 1, position: 10
-; (list)
+### Mode Option
+`-m` or `--mode` helps you specify the standard library mode:
 
-tests/demo_error.scm => wrong-type-arg
-> bin/goldfish tests/demo_argv.scm 1 2 3
-("bin/goldfish" "tests/demo_argv.scm" "1" "2" "3")
-tests/demo_argv.scm => #\newline
-```
-Notice, the FILE and the eval result are separated by ` => `.
++ `default`: `-m default` is the equiv of `-m liii`
++ `liii`: Goldfish Scheme with `(liii oop)`, `(liii base)` and `(liii error)`
++ `scheme`: Goldfish Scheme with `(liii base)` and `(liii error)`
++ `sicp`: S7 Scheme with `(scheme base)` and `(srfi sicp)`
++ `r7rs`: S7 Scheme with `(scheme base)`
++ `s7`: S7 Scheme without any extra library

+# [200_41] 更新 README.md 中的命令引用
+
+## 任务相关的代码文件
+- README.md
+
+## 如何测试
+验证命令示例正确性：
+```bash
+bin/gf version
+bin/gf eval "(+ 1 2)"
+bin/gf load tests/goldfish/liii/base-test.scm
+bin/gf tests/goldfish/liii/base-test.scm
+```
+
+## 2026-03-21 更新命令引用从 bin/goldfish 到 bin/gf
+
+### What
+1. 将所有 `bin/goldfish` 引用更新为 `bin/gf`
+2. 将版本号更新为 `17.11.30`
+3. 将 S7 Scheme 版本更新为 `11.5 (22-Sep-2025)`
+4. 重写 Commandlinefu 章节，将旧选项风格 (`-e`, `-l`, `--version`) 更新为子命令风格 (`eval`, `load`, `version`)
+5. 更新文件示例路径（移除不存在的 demo_*.scm）
+
+### Why
+之前 CLI 重构已经将 `goldfish` 重命名为 `gf`，并将选项风格改为子命令风格，但 README.md 中的文档示例仍然使用旧的命令名和选项风格，需要保持文档与实际命令一致。
