Right following our conversation:

This is a if statement I did which doesn't seem to work?

Code:
if [ -s /bin/bash ]
then 
     echo "file /bin/bash exists"
else
     echo "file /bin/bash exists"
fi

If I do a search ./test -s mylist1.html

it displays files exists

but the if I type ./test -s mylist14.html

still says the same

1. You tell it to print the same thing whether the test succeeds or fails.

2. You don't use the command-line argument anywhere. You are always testing for /bin/bash.

Code:
case $1 in
     -s) searchstring=$2 ;;
esac

if [ -s "$searchstring" ]
then
  echo  "file $searchstring exists"
else
  echo  "file $searchstring does not exist"
fi

Thanks for correction!

Now, if I only run ./test in the terminal to create my .html files it shows the echo message "file does not exists" even though I didn't pass in the '-s' argument!

Did you fix your wget statement? The one you posted has no URL.

Yup!

Code:
wget -tl -E -e robots=off - - awGet.log -T 200 -H -Priserless -O mylist1.html -U "Mozilla" "http://www.google.co.uk/search?classical+music&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a"

Okay, my script is basically on the first page.

Now, if I make another .html file and type into the terminal to run my script like this:
Quote:
kevin@ubuntu:~/Documents/Practice$: ./test
The output is:
Quote:
kevin@ubuntu:~/Documents/Practice$: ./test
file does not exists
kevin@ubuntu:~/Documents/Practice$: ./test
Basically my .html are being created but the message file does not exists is displayed. Although if I run ./test -h, it displays echo help
as expected.

Its only displaying file does not exists if i run the file as ./test without passing any argument.

Also since I dont pass the searchphrase, message shouldn't be displayed!
