What's Wrong?

I am unable to run claude code as CLI in my HPC environment.

This seems to be when it is scanning files, but I'm not entirely certain. I can move to a clean dir and start claude, but after saying i trust the files, the banner shows, and a short (1-2 sec) time later it silently drops to the shell. Exit code 0.

I have tried clearing my .claude and .claude.json and everything I can think of.

I can run the print mode (echo "hello" | claude -p) and it seems fine.

This is version 2.0.50, and I don't have node installed, appears to be using bundled version v24.3.0.
(This has also failed on several earlier versions)

Debug logs are unhelpful. They just end without any indication of failure.
Trying to track this down using the claude web interface, we thought it was getting too many files in ripgrep, but this happens even in brand new dir.

Looking at strace with claude web, it suggested that the terminal is exiting gracefully - unclear why.

Tried this in gnu screen, same issue.

I am in ssh session to HPC environment (RHEL/CentOS based, WekaFS filesystem) (but also fails in /tmp/claude-test)

This happens in my own instances, not login head node.

Note that this HPC uses symlinks for /home, which means the physical and logical directories don't match.

I am able to run the vs code extension using an ssh session, but I had to make a symlink inside of ~/.claude/projects to get claude to see my project history.

$ ll
total 17
lrwxrwxrwx 1 kqt4tu users    52 Nov 23 21:20 -home-kqt4tu-src-mydir -> -sfs-gpfs-tardis-home-kqt4tu-src-mydir
drwx--S--- 2 kqt4tu users 16384 Nov 23 21:53 -sfs-gpfs-tardis-home-kqt4tu-src-mydir

This /home symlink seems to be the source of endless fun, and it wouldn't be surprising if that's related.

What Should Happen?

claude cli should not silently drop to shell.
