Bash config文件在源于Perl脚本时抛出错误

有一行perl代码,在它发出消息后调用bash包装器函数 .bash_profile

system ('source ~/.bash_profile; osascript -e \'quit app "Chromium"\'');

/Users/me/.bashrc: line 9: syntax error near unexpected token `<'
/Users/me/.bashrc: line 9: `  done < <(find -L "$1" -type f -not -name *.swp -print0 | LC_COLLATE=C sort -dz)'

这是函数中的问题 .bashrc 文件:

source_dir() {
  while IFS= read -r -d $'\0' file; do
    source_file "$file"
  done < <(find -L "$1" -type f -not -name *.swp -print0 | LC_COLLATE=C sort -dz)
}

我运行的是bash 5.0.2版。
