LS -R --ignore directories?

[rm-rfme]

Hi. Trying to use ls to list all files in a directory and sub-directories, but not show the actual directories. I have written a small script to count the # of lines within these files, but because of the way ls -R works, the script counts sub directories as a line.

the below is to be used either alone (keyboard entered lines counted) or have some input redirected to it.

#script lc
if [ "$1" != "" ]
        then
                echo "Error: no arguments allowed."
                exit
fi

linecount=0
while read input
do
        linecount=$((linecount+1))
done

this is "rtlc", which is to get some files in the dir, and subdirs, and then call lc to count the lines. args requirement is a directory

echo $1

ls -R $1 | ./lc


#if [ -f $file1 ] ##test for file / dir.

I can't make this thing not count the sub directories as lines. Am I missing an ls option or char that can eliminate these? Scope does not allow for any external commands (like grep out the directories or use find)

[techstress]

can you pipe the ls into grep and use the following switch

-v
--invert-match
Invert the sense of matching, to select non-matching lines.

I wish. Project specs say no external commands are to be used aside from LS. I can do ls -Rp to show / in the directory names, maybe output to a file, loop iterate the file and skip lines containing "/", but this of course uses external commands as well.

Thoughts?

Do you get to edit the "lc" script? That would be a place to reject directory names. Also to reject blank lines, which accompany each directory name.

Otherwise I think you have a "you can't get there from here" project spec.

You could build from the following to reject all directory names (ending by /) and descriptions (ending by without using any external commands, it's essentially parsing the output of ls.

l=$(ls -R -1 ~/tmp)
for f in $l;do
 ln=${#f}
 ln=$((ln-1))
#GET THE LAST CHAR
 lst=${f:$ln}
 [ "$lst" != ":" ] && [ "$lst" != "/" ] && echo $f && linecount=$((linecount+1))
done
