What's Wrong?

When running a bash command that contains both a pipe (|) and a path with a tilde and space (e.g., ~/test/hello\ world/), tilde expansion fails and the command returns "No such file or directory".

Steps to reproduce:
#Ask claude code to run this, it works
ls -la ~/test/hello\ world/

#Ask claude code to run this, it fails
ls -la ~/test/hello\ world/ | head -15
#Error: ls: ~/test/hello world/: No such file or directory

The root cause issue after claude code debugged cli.js (which had the same issue):

For piped commands, the NJK function parses the command into tokens using shell-quote, then quotes each token individually before reassembling. When a path contains a space, shell-quote wraps it in single
quotes: '~/test/hello world/'. This traps the tilde inside single quotes, preventing shell expansion.

The final command passed to eval becomes:
eval "ls -la '~/test/hello world/' < /dev/null | cat"

Since tilde expansion doesn't occur inside single quotes in bash, the literal ~/test/hello world/ path is used instead of the expanded /Users/name/test/hello world/.

What Should Happen?

the bash command should do tilde expansion correctly and list the folder contents
