Write a shell script named displayargs that prints FOUR lines. The first line tells the name that was used to invoke the script, the second line tells how many parameters there were, the third line tells what the last parameter was, and the fourth line tells what the first parameter was.
For example:
$ displayargs a b c
My name is displayargs.
There were 3 parameters.
The last one was c.
The first one was a.
Jump to PostYou need to use $0 - $3 (and $#, etc) in your code. Try again. And then post your code. No one here is just going to give it to you.
Jump to PostDid you include a "#!" line in the script (if you don't know what I mean, that means you didin't)?
If not, what is your shell?
If yes, what shell did you use (hopefully a bourne based and not a c based)?

i tried this but but the output is different from the one above?
echo "My name is $0"
echo "There were $# parameters"
echo "The last is ${!#}"
echo "The first is $1"

Works for me, but it wouldn't for you if you were using a c-based shell (csh, tcsh, maybe others). That's why I asked, since you said it wasn't "working".
How does the output differ from what's expected?
this the output i got which is not the same with the above? isn't?should i change something?
my name is ./display
there were 0parameters
the last is ./dispaly args
the first is
It looks as though you executed the script without any arguments.
I.E.
./displayinstead of
./display a b cit works for me thank u so much brother..
