sgpt "nginx default config file location" 
# -> The default configuration file for Nginx is located at /etc/nginx/nginx.conf.shellsgpt "mass of sun" # -> 1.99 × 10^30 kgshellsgpt "1 hour and 30 minutes to seconds" # -> 5,400 seconds


sgpt "mass of sun"
# -> = 1.99 × 10^30 kg


sgpt "1 hour and 30 minutes to seconds"
# -> 5,400 seconds

With ShellGPT, you can access information and obtain answers without the need for extensive internet searches or referring to cheat sheets.

2. Summarization and Analyzing

ShellGPT offers the flexibility to accept prompts from both standard input (stdin) and command-line arguments. This versatility allows you to choose the most convenient input method based on your preferences. You can use ShellGPT to summarize and analyze text, making it particularly useful when you need to process file content or pipe output from other commands. For example:

git diff | sgpt "Generate git commit message, for my changes"
# -> Commit message: Implement Model enum and get_edited_prompt()

You can also analyze logs from various sources by passing them through stdin or as command-line arguments, along with a user-friendly prompt. This feature enables you to quickly identify errors and receive suggestions for possible solutions. For instance:

docker logs -n 20 container_name | sgpt "check logs, find errors, provide possible solutions" 
# ...

By leveraging ShellGPT's summarization and analysis capabilities, you can streamline your data management and troubleshooting processes.

3. Shell Commands

ShellGPT acts as a handy reference for common shell commands. With the --shell or -s option, you can quickly search for and execute shell commands directly in your terminal. For example:

sgpt --shell "make all files in current directory read only"
# -> chmod 444 *
# -> [E]xecute, [D]escribe, [A]bort: e
...

ShellGPT is aware of your operating system and the shell you are using, ensuring that it provides relevant commands for your specific setup. Whether you are using Linux, macOS, or Windows with popular shells such as PowerShell, CMD, Bash, Zsh, or Fish, ShellGPT has got you covered.

You can also use ShellGPT to describe suggested shell commands. It provides concise explanations of what each command does, helping you understand their functionalities. For instance:

sgpt --shell "make all files in current directory read only"
# -> chmod 444 *
# -> [E]xecute, [D]escribe, [A]bort: e
...

ShellGPT empowers you to execute shell commands efficiently, eliminating the need for constant internet searches or referring to documentation.

4. Shell Integration

ShellGPT offers seamless integration with your terminal through hotkeys. This feature, currently available for Bash and Zsh, allows you to have ShellGPT completions in your shell history and edit suggested commands on the fly.

To install shell integration, run the following command:

sgpt --install-integration
# Restart your terminal to apply changes.

Once installed, you can use a hotkey (e.g., Ctrl+l by default) to invoke ShellGPT, replacing your current input line with a suggested command. You can then edit the command as needed and press Enter to execute it.

Shell integration enhances your productivity by providing quick access to ShellGPT's suggestions and enabling interactive editing of commands.

5. Generating Code

ShellGPT excels at generating code snippets to assist in your development tasks. By using the --code parameter, you can query ShellGPT to generate code based on a specific prompt. For example:

sgpt --code "Solve classic fizz buzz problem using Python"

The result:

for i in range(1, 101):
    if i % 3 == 0 and i % 5 == 0:
        print("FizzBuzz")
    elif i % 3 == 0:
        print("Fizz")
    elif i % 5 == 0:
        print("Buzz")
    else:
        print(i)

You can redirect the output to a file for further use:

sgpt --code "solve classic fizz buzz problem using Python" > fizz_buzz.py
python fizz_buzz.py
# 1
# 2
# Fizz
# 4
# Buzz
# Fizz
# ...

ShellGPT also supports piped input for code generation. For example:

cat fizz_buzz.py | sgpt --code "Generate comments for each line of my code"

The result:

# Loop through numbers 1 to 100
for i in range(1, 101):
    # Check if number is divisible by both 3 and 5
    if i % 3 == 0 and i % 5 == 0:
        # Print "FizzBuzz" if number is divisible by both 3 and 5
        print("FizzBuzz")
    # Check if number is divisible by 3
    elif i % 3 == 0:
        # Print "Fizz" if number is divisible by 3
        print("Fizz")
    # Check if number is divisible by 5
    elif i % 5 == 0:
        # Print "Buzz" if number is divisible by 5
        print("Buzz")
    # If number is not divisible by 3 or 5, print the number itself
    else:
        print(i)

ShellGPT's code generation capabilities empower you to quickly obtain code snippets tailored to your requirements, enhancing your development workflow.

6. Chat Sessions

ShellGPT supports chat sessions, allowing you to engage in interactive conversations with the GPT models. You can start a chat session using the --chat option, providing a unique session name and a prompt. For example:

sgpt --chat number "please remember my favorite number: 4"
# -> I will remember that your favorite number is 4.
sgpt --chat number "what would be my favorite number + 4?"
# -> Your favorite number is 4, so if we add 4 to it, the result would be 8.

Chat sessions enable iterative improvements by providing additional clues to the GPT models. You can refine the results and engage in dynamic conversations to obtain more accurate and relevant responses.

7. REPL (Read–Eval–Print Loop) Mode

ShellGPT offers a REPL mode for interactive chatting with the GPT models. To start a chat session in REPL mode, use the --repl option followed by a unique session name. For example:

sgpt --repl temp
Entering REPL mode, press Ctrl+C to exit.
>>> What is REPL?
REPL stands for Read-Eval-Print Loop. It is a programming environment ...
>>> How can I use Python with REPL?
To use Python with REPL, you can simply open a terminal or command prompt ...

REPL mode allows you to interactively chat with the GPT models, receiving immediate responses and refining your queries as you go. It is a convenient way to explore the capabilities of ShellGPT and obtain real-time assistance.
