I don't want to plagerize so I give credit to Dale Dougherty and Arnold Robins who wrote "sed and awk" which I mentioned in my previous post (you really should buy it). It may not be exactly what you want but should be really close:

#!/bin/sh
ls -sl $* | awk'
#filesum: list files and total size in bytes
#input: long listing produced by "ls -l"

#1 output column headers
BEGIN { print "BYTES", "\t", "FILE" }

#2 test for 9 fields; files begin with "-"
NF == 9 && /^-/ {
sum += $5 # accumulate size of file
++filenum # count number of files
print $5, "\t", $9 # print size and filename
}

#3 Test for 9 fields; directory begins with "d"
NF == 9 && /^d/ {
print "<dir>", "\t", $9 #print <dir> and name>
}

#4 test for ls -lR line .dir:
$1 ~ /^\..*:$/ {
print "\t" $0 #print that line proceeded by a tab
}

#5 once all is done,
END {
#print total file size and number of files
print "Total: ", sum, "bytes (" filenum " files)"
}'


This will count the total number of files and their total combined size. I highly recommend the sed and awk book. I actually carry it in my briefcase all the time because it is just such a good reference book and awk is such a powerfull tool. It is well worth the time to learn the ins and outs of awk.

shtool-path

SHTOOL-PATH.TMP(1)					      GNU Portable Shell Tool						SHTOOL-PATH.TMP(1)

NAME

       shtool-path - GNU shtool command dealing with shell path variables

SYNOPSIS

       shtool path [-s|--suppress] [-r|--reverse] [-d|--dirname] [-b|--basename] [-m|--magic] [-p|--path path] str [str ...]

DESCRIPTION

       This command deals with shell $PATH variables. It can find a program through one or more filenames given by one or more str arguments.  It
       prints the absolute filesystem path to the program displayed on "stdout" plus an exit code of 0 if it was really found.

OPTIONS

       The following command line options are available.

       -s, --suppress
	   Supress output. Useful to only test whether a program exists with the help of the return code.

       -r, --reverse
	   Transform a forward path to a subdirectory into a reverse path.

       -d, --dirname
	   Output the directory name of str.

       -b, --basename
	   Output the base name of str.

       -m, --magic
	   Enable advanced magic search for ""perl"" and ""cpp"".

       -p, --path path
	   Search in path. Default is to search in $PATH.

EXAMPLE

	#   shell script
	awk=`shtool path -p "${PATH}:." gawk nawk awk`
	perl=`shtool path -m perl`
	cpp=`shtool path -m cpp`
	revpath=`shtool path -r path/to/subdir`

HISTORY

       The GNU shtool path command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken
       over into GNU shtool.
