Checklist

• I have read through the manual page (man fzf)
• I have searched through the existing issues
• For bug reports, I have checked if the bug is reproducible in the latest version of fzf

Output of fzf --version

0.73.1 (ce4bef7)

OS

• Linux
• macOS
• Windows
• Etc.

Shell

• bash
• zsh
• fish
• nushell

Problem / Steps to reproduce

The shell configuration update check still assumes there are only 3 supported shells (bash, zsh, and fish). Since nushell support was added, the condition is outdated.

if [[ ${#shells} -lt 3 ]]; then
  echo "No shell configuration to be updated."
  exit 0
fi

Proposed Solution

Update the count from 3 to 4

if [[ ${#shells} -lt 4 ]]; then
  echo "No shell configuration to be updated."
  exit 0
fi
