print summary of directory, and group all symbolic links
I am trying to get a summary of filetypes in a directory, but the total count of symbolic links is not working. I am stuck at the results of the file command. I have used the find command to confirm my expectations, but my bash function is not giving the results I want.

Here is my function:
Code:
function summ ()
{
	echo					# intentional blank line
	echo -en "[${HOSTNAME}:${PWD}]"; echo
	for FILE in * ; do			# intentionally not recursive
		FILETYPE=`file "$FILE" | cut -d ":" -f 2`
		echo $FILETYPE >> /tmp/.dir_summary 
	done
	cat /tmp/.dir_summary | sort | uniq -c
	\rm /tmp/.dir_summary		# skip alias='rm -Iv'
	echo -en "$[Total == "`/bin/ls $@|wc -l`" @"\
		`du -h --max-depth=0 2>/dev/null | cut -c -4`"]"; echo
	}

And here is my find command to confirm the number of symbolic links:
Code:
find . -maxdepth 1 -mindepth 1 -type l | wc -l

Result:
Code:
16

Here is my actual output of /etc:
Code:
[lap-fedora13:/etc]
      1 ASCII C program text
      1 ASCII C++ program text
     43 ASCII English text
      1 ASCII English text, with escape sequences
      2 ASCII Pascal program text
     51 ASCII text
      1 ASCII text, with very long lines
      2 data
    119 directory
      9 empty
      9 regular file, no read permission
      1 symbolic link to `../boot/grub/grub.conf'
      2 symbolic link to `fedora-release'
      1 symbolic link to `rc.d/init.d'
      1 symbolic link to `rc.d/rc'
      1 symbolic link to `rc.d/rc0.d'
      1 symbolic link to `rc.d/rc1.d'
      1 symbolic link to `rc.d/rc2.d'
      1 symbolic link to `rc.d/rc3.d'
      1 symbolic link to `rc.d/rc4.d'
      1 symbolic link to `rc.d/rc5.d'
      1 symbolic link to `rc.d/rc6.d'
      1 symbolic link to `rc.d/rc.local'
      1 symbolic link to `rc.d/rc.sysinit'
      1 symbolic link to `../sbin/rmt'
      1 symbolic link to `/usr/share/icons/hicolor/16x16/apps/fedora-logo-icon.png'
      1 timezone data, version 2, 5 gmt time flags, 5 std time flags, no leap seconds, 235 transition times, 5 abbreviation chars
      1 UTF-8 Unicode English text
[Total = 256 @ 26M ]

And the expected text:
Code:
[lap-fedora13:/etc]
      1 ASCII C program text
      1 ASCII C++ program text
     43 ASCII English text
      1 ASCII English text, with escape sequences
      2 ASCII Pascal program text
     51 ASCII text
      1 ASCII text, with very long lines
      2 data
    119 directory
      9 empty
      9 regular file, no read permission
     16 symbolic link 
      1 timezone data, version 2, 5 gmt time flags, 5 std time flags, no leap seconds, 235 transition times, 5 abbreviation chars
      1 UTF-8 Unicode English text
[Total = 256 @ 26M ]

I know that both file and du are reading the entire directory once apiece, so I am trying to avoid a third read (with find).

I have given some thought to pipe the output to a second /tmp/file, and somehow use the cut -d (delimiter) option to group the symbolic links, and then uniq -c (gasp) again, but in the example above, there are 2 symbolic links to `fedora-release' and my count would be off.
