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.

You could replace
Code:
cut -d ":" -f 2

with
Code:
sed 's/[^:]*://; s/^ symbolic link to.*/ symbolic link/'

In all cases, it removes everything up to the first colon, inclusive. In the case of symbolic link, it'll strip away everything beginning with the space after "symbolic link".

Except for deleting the target of a symbolic link, it should yield output identical to your cut approach so that subsequent commands require no modification.
