csh script for listing files and directories

I am trying to create a script in UNIX that will list the files in the
current directory. Also, if there is a another directory within the
current directory it will list its contents. I am fairly new to csh. I
was able to get the first part where the contents of the current
directory is printed. I am having trouble with how to go to the next
directory and print its contents.

Here is a sample of what I have so far:

foreach file (*)
if (-d $file) then
echo $file "(directory)"
else if (-e $file) then
echo $file "(file)"
end

The output would look something like this:

a(file)
b(directory)
c(file)

Hi Matt,
I hope the below script will do for u.

#!/usr/bin/csh
foreach abc (`find . -name "*"`)
set ab=`echo $abc | wc -c`
if ( $ab > 2 ) then
if ( -d $abc ) then
set File=`echo $abc | cut -c3-$ab`
echo " Directory :: $File"
else if ( -e $abc ) then
set File=`echo $abc | cut -c3-$ab`
echo " File :: $File"
endif
endif
end

Thanks,
dattu

Modified one ...

#!/usr/bin/csh
foreach abc (`find . -name "*" -exec basename {} \;`)
if ( -d $abc ) then
echo " Directory :: $abc"
else if ( -e $abc ) then
echo " File :: $abc"
endif
end

Thanks,
Dattu

You have been given a couple of answers, but before you spend too
much time learning csh, you should read these:

In the Bourne shell (/bin/sh),
you can even have a recursive routine,
that will find/list the entire directory tree:

#!/bin/sh
readdir(){
for file in "$1"/*
do
if [ -f "$file" ]; then
echo "$file (file)"
elif [ -d "$file" ]; then
echo "$file (directory)"
readdir "$file"
fi
done
}
readdir "."

But in C-Shell you cannot do such things.

I would use find (GNU find, actually):
find . -type f -printf '%p (file)\n' -o -type d -printf '%p (directory)\n'
