Methods which process the output from "ls -la" are prone to spurious matches and problems with filenames containing space characters. None of the examples posted so far really work.

Another approach. Find all the files in the directory which were created after midnight. The filenames are available in the centre of the do-done loop if you need to do further processing.

Code:
YYYYMMDD="`date +%Y%m%d`"       # Reversed date yyyymmdd
REFERENCE=/var/tmp/reference.${YYYYMMDD}.$$
touch -t ${YYYYMMDD}0000 ${REFERENCE}
#
ls -1d * 2>/dev/null | while read FILENAME
do
     if [ -f "${FILENAME}" -a "${FILENAME}" -nt "${REFERENCE}" ]
     then
           echo "${FILENAME}"
     fi
done 
#
rm ${REFERENCE}

There is a better method using just "find" but we don't know whether your directory has subdirectories.

LEARN ABOUT NETBSD

info

INFO(1) 							   User Commands							   INFO(1)

NAME

       info - read Info documents

SYNOPSIS

       info [OPTION]... [MENU-ITEM...]

DESCRIPTION

       Read documentation in Info format.

OPTIONS

       --apropos=STRING
	      look up STRING in all indices of all manuals.

       -d, --directory=DIR
	      add DIR to INFOPATH.

       --dribble=FILENAME
	      remember user keystrokes in FILENAME.

       -f, --file=FILENAME
	      specify Info file to visit.

       -h, --help
	      display this help and exit.

       --index-search=STRING
	      go to node pointed by index entry STRING.

       -n, --node=NODENAME
	      specify nodes in first visited Info file.

       -o, --output=FILENAME
	      output selected nodes to FILENAME.

       -R, --raw-escapes
	      output "raw" ANSI escapes (default).

       --no-raw-escapes
	      output escapes as literal text.

       --restore=FILENAME
	      read initial keystrokes from FILENAME.

       -O, --show-options, --usage
	      go to command-line options node.

       --subnodes
	      recursively output menu items.

       -w, --where, --location
	      print physical location of Info file.

       --vi-keys
	      use vi-like and less-like key bindings.

       --version
	      display version information and exit.

       The first non-option argument, if present, is the menu entry to start from; it is searched for in all `dir' files along INFOPATH.  If it is
       not present, info merges all `dir' files and shows the result.  Any remaining arguments are treated as the names of menu items relative	to
       the initial node visited.

EXAMPLES

       info   show top-level dir menu

       info emacs
	      start at emacs node from top-level dir

       info emacs buffers
	      start at buffers node within emacs manual

       info --show-options emacs
	      start at node with emacs' command line options

       info -f ./foo.info
	      show file ./foo.info, not searching dir
