counts the number of distinct words

[Net-Man]

I'm looking to write a sample shell script that counts the number of distinct words in a text file given as Argument.
Remark: White space characters are spaces, tabs, form feeds, and new lines.

JUST with this commands tr, sort, grep. wc.

Thanks.

That's a pretty arbitrary limitation, but it sure makes for a good assignment. It tests your ability to come to a conclusion with limited resources.

When does your instructor say this assignment is due?

Hi,

No this not HW and second i try many times and then i posted here to get a help and that is my try to solve it:

grep -c | sort -u test.txt | tr -d "\t \v \f [unct:] [:upper:] "

but actually i don't know how i can sort this commands ??

Why are you restricted to using tr, sort, grep, and wc?

Because just this commands i can work with them clearly and plus ther is many references i found it on the net explain how i can used, so now i know how i can use this commands but i don't know how i can combine them.

Sounds to me like all you need is wc. Take the file you get in the command line and run it through that.

Depends on what he means by "distinct".
