AutoSudo

Press Esc Esc to instantly prepend sudo to your current command line — no retyping, no copy-paste.

$ apt update        ← you type this
$ sudo apt update   ← after pressing Esc Esc

---

Requirements

• bash 3.0+ (the script does not support sh, zsh, fish, or other shells)
• A Unix-like system (Linux, macOS, WSL)

---

Installation

The installer will:

1. Verify you are running bash.
2. Create ~/.bashrc if it does not exist.
3. Back up your existing ~/.bashrc to ~/.bashrc.autosudo.bak.
4. Append the AutoSudo block, clearly delimited by markers, to ~/.bashrc.

One-liner (curl)

curl -sSL https://raw.githubusercontent.com/insanerask77/bash_sudo_funtion/main/install.sh | bash

One-liner (wget)

wget -qO- https://raw.githubusercontent.com/insanerask77/bash_sudo_funtion/main/install.sh | bash

Manual

git clone https://github.com/insanerask77/bash_sudo_funtion.git
cd bash_sudo_funtion
bash install.sh

Activate

After installation, reload your shell configuration:

source ~/.bashrc

Or simply open a new terminal.

---

Usage

1. Type any command in your terminal.
2. Press Esc twice.
3. sudo is prepended and your cursor is repositioned after it.

Before	After Esc Esc
apt update	sudo apt update
systemctl restart nginx	sudo systemctl restart nginx
nano /etc/hosts	sudo nano /etc/hosts

If the command already starts with sudo, pressing Esc Esc has no effect.

How it works

The installer appends the following block to ~/.bashrc:

# BEGIN AUTOSUDO - DO NOT EDIT THIS BLOCK
_autosudo() {
    if [[ "$READLINE_LINE" != sudo\ * ]]; then
        READLINE_LINE="sudo $READLINE_LINE"
        READLINE_POINT=$(( READLINE_POINT + 5 ))
    fi
}
bind -x '"\e\e": _autosudo'
# END AUTOSUDO - DO NOT EDIT THIS BLOCK

bind -x maps the double-Escape sequence (\e\e) to the _autosudo shell function. The function modifies READLINE_LINE (the current input buffer) and advances READLINE_POINT (the cursor) by 5 characters — the length of "sudo ".

---

Uninstallation

The uninstaller removes the AutoSudo block from ~/.bashrc using the delimiters written at install time.

One-liner (curl)

curl -sSL https://raw.githubusercontent.com/insanerask77/bash_sudo_funtion/main/uninstall.sh | bash

One-liner (wget)

wget -qO- https://raw.githubusercontent.com/insanerask77/bash_sudo_funtion/main/uninstall.sh | bash

Manual

bash uninstall.sh

Then reload your shell:

source ~/.bashrc

Manual uninstallation (fallback)

Open ~/.bashrc in any editor and delete the block between:

# BEGIN AUTOSUDO - DO NOT EDIT THIS BLOCK

and:

# END AUTOSUDO - DO NOT EDIT THIS BLOCK

including both marker lines. To restore the backup created at install time:

cp ~/.bashrc.autosudo.bak ~/.bashrc
source ~/.bashrc
