I know about the sort command with -u option and that it works

What i meant to say that the command which you have given is not the total solution for the question posted above. But that is again what i think, you may be right as well.

This is what I got from your command
Quote:
$cat abc.txt
v b s a e
r
t
g
hg gf v s

$sort -u abc.txt | wc
5 12 28
but as per my understanding the output should have been 10 and not 12

ok i was working with the first idea. here is what i have so far. but for some reason this is not working, the command works but i think there is a problem with the input.

Code:
#!/bin/csh

echo "Please enter a filename: "
set filename = $<

set dif = `tr -d '.:"$(),-' < $filename | tr '[A-Z]' '[a-z]' | tr ' ' '\n' | sort | uniq | wc -l`
set num = `wc -l`

echo "Thank you, your file has $num words and $dif different words."

echo " "

maybe someone can catch it..

got that but the thing is in the command you have wriiten in the script to set num you have forgotten to mention the name of the file

set num = `wc -l filename`

Ok this is the output im getting, why is the echo statement messed up.
Please enter a filename:
testfile.txt
words.ou, your file has 239 words and 159

heres the code:
Code:
#!/bin/csh

echo "Please enter a filename: "

set filename = $<

set num = ` wc -w $filename | awk '{ print $1 } ' `
set dif = `tr -d '.:"(),-' < $filename | tr '[A-Z]' '[a-z]' | tr ' ' '\n' | sort | uniq | wc -l`

echo "Thank you, your file has $num words and $dif different words."

echo " "
