The error you get is because bash is looking for the end of the if block and can't find it before the end of the file, that's why the error is for line 45.

Now, you have various syntax errors, first of all, an if block looks like this:

if [ test something ]

then

    do something

fi

The keywords then and fi are needed. Then, you should quote the variables and strings inside the [ ] test construct, and you should also be aware that your script will break on spaces and unexpected input.

A working version of your script would be:

#!/bin/bash 

clear 



echo "Hello Sir How are you? These are some of my features

date

picture"



read word



if [ "$word" = "picture" ]

then

echo "These are the following pictures I have at my disposel: 

Dog"

fi





if [ "$word" = "date" ]

then

    w

fi



read word



if [ "$word" = "dog" ]

then

echo "

Note that you still have design problems, this is not a well written script, apart from not handling any errors, you also don't exit if any of the choices are entered which means that no matter what I do, I will eventually get to the dog printing. Even if I enter date, you might want to add some exit calls in there.
