sshpass - Go Rewrite Version

This is a Go language rewrite of the sshpass tool, providing full compatibility with the original version's command-line interface and functionality.

Features

• ✅ Fully compatible command-line options with original sshpass
• ✅ All password input methods (-f, -d, -p, -e, default stdin)
• ✅ Detailed error handling and help information
• ✅ Cross-platform support (Windows, macOS, Linux)
• ✅ No external dependencies (pure Go implementation)

Installation

go install github.com/ai-help-me/sshpass@latest

Usage

Basic Syntax

sshpass [-f|-d|-p|-e] [-hV] command parameters

Options

• -f filename - Read password from file
• -d number - Use specified file descriptor for password
• -p password - Provide password directly (insecure)
• -e - Get password from environment variable SSHPASS
• -P prompt - Set password prompt string (default: password)
• -v - Verbose output mode
• -h - Display help information
• -V - Display version information

Examples

1. Provide password from command line

sshpass -p mypassword ssh user@host

2. Get password from environment variable

export SSHPASS=mypassword
sshpass -e ssh user@host

3. Read password from file

echo "mypassword" > pass.txt
sshpass -f pass.txt ssh user@host

4. Use verbose mode

sshpass -v -p mypassword ssh user@host

5. Execute remote command

sshpass -p mypassword ssh user@host "ls -la"

6. Use scp to transfer files

sshpass -p mypassword scp file.txt user@host:/remote/path/

Compatibility with Original Version

This implementation is fully compatible with the original sshpass. All command-line options and behaviors remain consistent, allowing seamless replacement of existing sshpass usage scenarios.

Security Notes

• Providing password directly in command line (-p option) is insecure as it appears in process listing
• Recommended to use file (-f) or environment variable (-e) methods for password input
• Password files should have appropriate permissions (e.g., 600) to protect password security

Build Requirements

• Go 1.16 or higher
