What's Wrong?

The Bash tool doesn't seem to work -- every instance of Claude trying to call Bash results in no output and the generic error "Error: Exit code 1". Platform: Linux (Fedora 43, kernel 6.17.7).

Example output:

● Bash(echo "Hello from Bash")
  ⎿  Error: Exit code 1

● Bash(pwd)
  ⎿  Error: Exit code 1

This happens across multiple types of invocations -- in the VSCode integrated terminal, in my native Konsole terminal, using the VSCode extension, etc. Running !bash commands from within Claude Code fails similarly.

I've tried installing Claude Code natively, then uninstalled and reinstalled using NPM, and finally used claude migrate-installer to switch to a local install. I've tried both enabling and disabling sandbox mode. I've also tried disabling SELinux, as well as specifically enabling all Bash usage in Claude's permissions.

What Should Happen?

Bash commands should return with valid output and exit code 0. For example, Bash(echo "Hello from Bash") should return Hello from Bash and a success error code.

Error Messages/Logs

I see the following in the Claude debug logs, not associated with running the actual Bash commands but with creating shell snapshots:

Trouble running `/usr/bin/env bash` would certainly explain the issue! But that command works just fine in a regular terminal.

Steps to Reproduce

I can reproduce this with any request to Claude to use the Bash tool, but I don't think others will be able to. It seems specific to my environment somehow, although I haven't yet determined how.

Is this a regression?

Additional Information

I'm not clear whether this is a bug in Claude Code on Linux, or just some sort of issue with my local configuration. I'm posting here because after much troubleshooting, I was directed to do so by the Fin support agent:

Since you've completed the standard troubleshooting steps and the debug file isn't accessible here, you can use the /bug command within Claude Code to report this Bash tool issue directly to our team. This will send the relevant technical details including your debug information.

I'm attaching a debug file from a session using claude --debug:
