Why Does copaw app Open Infinite Terminal Windows? A Complete Diagnosis and Fix

You just installed CoPaw, typed copaw app into your terminal with excitement, and watched in horror as dozens — maybe hundreds — of terminal windows exploded across your screen with no sign of stopping. Your computer isn’t broken, and CoPaw isn’t fundamentally flawed. What you’re dealing with is a classic infinite self-calling loop triggered by an installation script, and there’s a single command that fixes it completely.

What’s Actually Happening?

To understand why this happens, it helps to know how macOS resolves a command when you type it in the terminal.

When you type copaw, your shell searches through the directories listed in the $PATH environment variable — in order, from left to right — until it finds an executable file with that name. The first match wins. Everything else is ignored.

After a normal CoPaw installation, a real launcher script is placed in ~/.copaw/bin/, and your ~/.zshrc gets one line added to it:

export PATH="$HOME/.copaw/bin:$PATH"

That part is completely fine and causes no problems on its own.

The problem comes from a different script entirely. Bundled with CoPaw is a file called setup_copaw_shortcut_user.sh, whose stated purpose is to create a desktop shortcut for launching CoPaw without needing sudo privileges. But in doing so, it creates a fake copaw file inside ~/bin/ that contains this:

#!/bin/bash
osascript -e 'tell application "Terminal" to activate' \
          -e 'tell application "Terminal" to do script "cd ~/.copaw && copaw"'

In plain English: use AppleScript to open a new Terminal window and run copaw inside it.

Here’s where the loop begins:

You type:  copaw
  → Shell finds ~/bin/copaw first  (the fake one)
  → Fake copaw opens a new Terminal window and runs copaw
  → New window finds ~/bin/copaw again  (still the fake one)
  → Opens another Terminal window and runs copaw
  → Opens another...
  → And another...
  → Until your Mac runs out of resources

That’s the entire root cause. One fake file with the wrong name in the wrong place.

Why Does the Fake File Take Priority?

This comes down to the order of directories in $PATH.

If ~/bin appears before ~/.copaw/bin in your $PATH, the shell finds the fake copaw file first and executes it — never reaching the real one. This behavior is known as command shadowing, and it’s one of the more common sources of mysterious terminal misbehavior.

You can check which copaw your shell is actually running with:

which copaw

If the output is:

/Users/your-username/bin/copaw

You’re running the fake one. The correct output should be:

/Users/your-username/.copaw/bin/copaw

Step 1: Stop the Runaway Terminals

Before doing anything else, shut down the cascade of windows that’s already open.

Option A: Press Command + Q to force-quit Terminal.app entirely. This closes all open terminal windows at once.

Option B: Open Activity Monitor (search for it in Spotlight with Command + Space), search for Terminal or osascript, select the processes, and click the force-quit button (the × icon in the top-left).

Option C: If you still have a working terminal window, run:

pkill -f osascript
pkill Terminal

Step 2: The One-Line Fix

Once the chaos is stopped, open a fresh terminal window (do not type copaw yet) and run:

rm ~/bin/copaw

That’s it. This removes the fake copaw file from ~/bin/. The real CoPaw installation — located in ~/.copaw/venv/bin/ and accessed through ~/.copaw/bin/copaw — is completely untouched.

Step 3: Verify the Fix

After deleting the fake file, confirm that copaw now points to the right place:

which copaw

You should see:

/Users/your-username/.copaw/bin/copaw

Then inspect the real launcher script to make sure it looks correct:

cat ~/.copaw/bin/copaw

A healthy ~/.copaw/bin/copaw looks like this:

#!/usr/bin/env bash
# CoPaw CLI wrapper — delegates to the uv-managed environment.
set -euo pipefail

COPAW_HOME="${COPAW_HOME:-$HOME/.copaw}"
REAL_BIN="$COPAW_HOME/venv/bin/copaw"

if [ ! -x "$REAL_BIN" ]; then
    echo "Error: CoPaw environment not found at $COPAW_HOME/venv" >&2
    echo "Please reinstall: curl -fsSL <install-url> | bash" >&2
    exit 1
fi

exec "$REAL_BIN" "$@"

Notice what’s not in there: no osascript, no new terminal windows, no recursive calls. It simply checks that the Python virtual environment exists, then hands off execution to the real CoPaw binary. Clean and straightforward.

Full Environment Audit: What Else to Check

If you want to make sure there are no other lingering issues, here’s a thorough walkthrough.

Scan Your Shell Config Files for CoPaw References

grep -rn "copaw" ~/.bashrc ~/.zshrc ~/.bash_profile ~/.profile ~/.config/ 2>/dev/null

Under normal circumstances, you should only see one result — the PATH entry in ~/.zshrc:

/Users/your-username/.zshrc:5:export PATH="$HOME/.copaw/bin:$PATH"

This line is harmless and should stay exactly as it is.

Inspect the CoPaw Directory Structure

ls ~/.copaw/

A properly installed CoPaw directory looks like this:

Review config.json for Unexpected Settings

cat ~/.copaw/config.json

Focus on two sections: channels and agents. By default, only the console channel has "enabled": true. All other channels — iMessage, Discord, Feishu, DingTalk, Telegram, QQ — are disabled out of the box and won’t affect your setup unless you’ve intentionally configured them.

Confirm Your PATH Order

echo $PATH | tr ':' '\n'

This prints each directory in your $PATH on its own line, in priority order. ~/.copaw/bin should be present. After the fix, even if ~/bin still appears in the list, it no longer contains a fake copaw file, so the loop cannot re-trigger.

The Bigger Picture: Why Installation Scripts Can Cause This

What happened here is a textbook case of command shadowing — a situation where a file with the same name as an existing command appears earlier in $PATH, causing the shell to execute the wrong one.

The setup_copaw_shortcut_user.sh script was designed with good intentions. On macOS, creating a user-level command shortcut in ~/bin/ is a common pattern for giving users a convenient, no-sudo way to launch tools globally. The script even includes instructions for binding the shortcut to a keyboard combination in System Settings.

The oversight is that the shortcut was named copaw — identical to the real command — and implemented using osascript to open a new Terminal window. That works fine as a desktop launcher. But when called from an existing terminal session, it creates a loop: each copaw invocation opens a new window, and each new window runs copaw again, ad infinitum.

The lesson here applies broadly: after installing any command-line tool, always run which command-name to confirm you’re executing what you think you are. It takes two seconds and can save you from a lot of confusion down the road.

What If copaw Returns “Command Not Found” After the Fix?

In rare cases, if ~/bin happened to be the only copaw in your $PATH (meaning ~/.copaw/bin was never properly added), deleting the fake file might leave you with no copaw at all.

First, check whether the PATH entry exists in your shell config:

grep "copaw" ~/.zshrc

If the line export PATH="$HOME/.copaw/bin:$PATH" is missing, add it manually:

echo 'export PATH="$HOME/.copaw/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

Then verify:

which copaw

FAQ

My terminal is already flooded with windows and I can’t do anything. What first?

Press Command + Q to quit Terminal.app entirely. This force-closes all windows at once. Once everything is shut down, open a single fresh terminal window and follow Step 2 above.

I ran setup_copaw_shortcut_user.sh intentionally. Is it safe to delete ~/bin/copaw?

Yes. Deleting ~/bin/copaw only removes the AppleScript-based launcher wrapper. The actual CoPaw installation in ~/.copaw/ is completely separate and unaffected. You’ll lose the ability to use a keyboard shortcut via System Settings to launch CoPaw in a new window, but the core tool works normally.

Will deleting ~/bin/copaw break anything in CoPaw itself?

No. CoPaw’s real runtime lives in ~/.copaw/venv/bin/copaw, accessed through the wrapper at ~/.copaw/bin/copaw. The file you’re removing is a redundant convenience script that only exists to support a desktop-shortcut workflow. Removing it has zero effect on CoPaw’s functionality.

Why did the installation script create this problem in the first place?

The script was designed to give users a no-sudo global shortcut. Using osascript to open a new Terminal window and launch the app is a reasonable macOS pattern — it mimics what clicking a .app icon does. The issue is that naming the shortcut copaw creates a name collision with the real command, and the osascript approach only makes sense when triggered by a keyboard shortcut or dock icon, not from within a terminal session.

How do I avoid this kind of issue with future tools?

Make it a habit: after installing any CLI tool, run which tool-name and inspect the output. If the path looks unfamiliar, run cat $(which tool-name) to see exactly what the file does before you execute it. This is especially useful whenever an installation script modifies your ~/bin/ or adds aliases to your shell config.

Do I need to change anything in config.json?

Not unless you’re intentionally setting up integrations with platforms like Discord, Telegram, or Feishu. The default configuration — with only the console channel enabled — is all you need to use CoPaw normally from the command line.

Summary

The infinite terminal window problem comes down to one thing: a fake copaw file in ~/bin/ that opens a new Terminal window and re-invokes itself every time it runs. It was placed there by setup_copaw_shortcut_user.sh, a bundled shortcut-creation script that works fine as a desktop launcher but causes an unintended recursion loop when called from the command line.

The fix is a single command:

rm ~/bin/copaw

After that, which copaw should point to ~/.copaw/bin/copaw, and everything runs as expected. If you want to double-check your environment, use grep -rn "copaw" ~/.zshrc to confirm only the PATH entry remains, and cat ~/.copaw/bin/copaw to verify the real launcher script looks clean.

One fake file. One command to remove it. Done.
