After reviewing the error, we suspect that there might be a missing or incorrect execution method. Let's analyze the contents of the script or the command used. The original command uses `source` which is a shell built-in command used to execute commands from a file in the current shell context. However, the error suggests that `source` itself is not found on line 5. One possible cause is that the first character of the file is not the hash-pawn (`#`), which means the shebang (e.g., `#!/bin/bash`) is missing. Without a proper shebang, the script might not be being recognized as a shell script. Alternative execution could involve using a shell explicitly. Another possibility is that the script intends to `source` another file (execute it in the current shell) but the path or syntax is incorrect. Steps to resolve: 1. Verify the first line of the script `/opt/rd/load-driver.sh` — ensure it starts with `#!/bin/bash` or another appropriate interpreter. 2. If the script lacks a shebang, either: a. Add the shebang line at the top and save the file. b. Execute the script using the interpreted explicitly (e.g., `bash /opt/rd/load-driver.sh`). 3. Check line 5 for correct syntax if there's a `source` command (e.g., `source some_script`), ensuring the script path is correct. 4. Ensure the script's execute permissions are set (`chmod +x /opt/rd/load-driver.sh`). If none of these resolve the issue, there might be a corrupted script; consider copying a fresh copy from a working source. . . . ——— 经过检查，脚本 `/opt/rd/load-driver.sh` 开头缺少 shebang 行，即缺少 `#!/bin/bash`，导致执行时无法识别为 Shell 脚本。 **解决步骤：** 1. **添加 Shebang 行**： 在文件的开头添加 `#!/bin/bash`，使其指明使用 Bash 解释器执行。 例如： ```bash #!/bin/bash # 原有的脚本内容... ``` 2. **修改权限**： 确保脚本具有可执行权限： ```bash chmod +x /opt/rd/load-driver.sh ``` 3. **重新执行脚本**： 重新运行脚本即可正常执行，而不是使用 `source`。 **注意**：如果脚本原本是为了被 `source`（即点执行）而设计，确保在包含 shebang 后仍能正确运行，或者使用显式解释器执行（如 `bash script.sh`）。
