"syntax error: unexpected end of file"

this is the test program
******************

read num
echo "Enter the choice of you want to see "
echo "1. 1message"
echo "2. 2message"

Change the "if" line to this: Note there the spaces after the "[" and before the "]" are required. Also, to access the value of a variable in shell, prefix the variable with a "$" sign. Use "fi" to close the "if" statement.

Code:

if [ $choice -eq 1 ] then
echo "This is reading the first choice"
fi

You can clean up your code by using a "select case" which will build the menu for you. Here is the syntax (note that the ";;" must end every case.)

Code:

select NUM in 1 2 3 quit
do
   case $NUM in
      1)  echo "This is reading the first choice"
           ;;
      2)  echo "This is reading the second choice"
           ;;
      3)  echo "This is reading the third choice"
           ;;
    quit) echo "Goodbye"
           exit;;
   esac
done

Lastly, to fancy it up a bit, use the builtin variable PS3 to set your prompt string for the menu (Add it just before the "select case" statement)

Code:

PS3="Make a Selection From the Following List"

Neither of the suggestions will work for the OP as he is using a csh base shell. I'm pretty rusty on csh but I think it should be something like

Code:

echo " enter number"
read num
echo "Enter the choice of you want to see "
echo "1. 1message"
echo "2. 2message"
echo "3. 3message"
read choice
if ( $choice == 1 ) then
    echo "This is reading the first choice"
endif
