would anyone know what is the difference in these two commands?
$ cat xyz[12]
$ cat xyz[1-2]

[secondmouse]

The results of these two commands (in this case) are identical. You can refer to A Brief Introduction to Regular Expressions for more info.

$ grep -c ill memo

$ grep -n ill memo

[secondmouse]

man grep
then in the man page, enter
/-c,
for explanation of option c;
then
/-n,
for explanation of option n

thanks what about this script - im stuck!

Write a script that will prompt for the user’s first name and store it in a variable. Then prompt for the last name and store it in a variable. Finally, display the stored information in the format “You entered lastname, firstname” and ask the user for confirmation. If the answer is “y” or “yes” then say “Thank you!” if the answer is “n” or “no” then start again with the prompts.

#!/bin/bash
declare FName
read -p "Enter First Name : " FName

declare LName
read -p "Enter Last Name : " LName
echo "you entered" $FName $LName

read -p "Is that correct?"
if [[ $YesNo = "Y,Yes" ]]
then
echo "Thankyou"

else
[[ $YesNo = "N,No" ]]

I'm pretty sure there are more than one way to accomplish this, here's one

#!/bin/bash
ans=''
while [ "$ans" !=  'Y' -a "$ans" != "YES" ]; do
    read -p "Enter First Name: " FName
    read -p "Enter Last Name: " LName
    echo "you entered: $FName $LName"
    read -p "Is that correct? (Y/N)" ans
    ans=`echo $ans|tr "[:lower:]" "[:upper:]"`
    case $ans  in
        Y|YES)
            echo "Thank you $FName $LName."
            ;;
        *)
            echo "Let's try again"
            ;;
    esac
done
