## 项目历史与用法

ssh-copy-id is the small OpenSSH-adjacent shell utility that installs a user's public SSH key into a remote account's authorized_keys file.

### 项目历史

OpenSSH itself began in 1999 when OpenBSD developers forked the free SSH 1.2.12/OSSH lineage, cleaned up licensing and portability issues, and shipped OpenSSH 1.2.2 with OpenBSD 2.6 on December 1, 1999. The portable OpenSSH tree was split out almost immediately for Linux and other Unix systems.

The ssh-copy-id script in the OpenSSH portable repository carries Philip Hands copyright from 1999 onward and describes itself as a shell script to install public keys on a remote machine. Over time it gained contributions for options such as force mode, dry-run mode, SFTP mode, alternate target paths, SSH config files, and port handling.

### 采用历史

ssh-copy-id became common Unix CLI glue because it automates the manual public-key setup described by ssh documentation: place a public key in the remote user's authorized_keys file. Homebrew packages it separately from the main OpenSSH formula for macOS users, while the input facts also list Nix and winget package names.

### 使用方式

The usual workflow is to run ssh-copy-id [-i identity_file] [user@]host. The script selects public keys from ssh-agent or from ${HOME}/.ssh/id*.pub, checks which keys are not already accepted, and appends the selected public keys to the remote .ssh/authorized_keys path unless a different target path is requested.

### 为什么软件包爱好者会关心

ssh-copy-id is package-manager folklore: a tiny shell script that saves users from remembering the exact ssh, mkdir, chmod, and cat incantation for public-key login setup. It is also a reminder that small contrib utilities can become first-class packages when operating systems omit them or users want them independently.
