   Ok niggers i wrote a shellscript to help with kernel managementm i 'fi'd` all my `ifs` i `esac'd` call my cases and i did all my `done'a`.
   
   

   
   #!/bin/bash
   
   if [[ "$EUID" -ne 0 ]]; then
      echo "This script must be run as root" 1>&2
      exit 1
   fi
   
   function logo()
   {	printf " _____             _____         "
   	printf "|  |  |___ ___ ___|     |___ ___ "
   	printf "|    -| -_|  _|   | | | | .'|   |"
   	printf "|__|__|___|_| |_|_|_|_|_|__,|_|_|"
   	printf "\nKernMan - Kernel Management Assistant.\n"}  
   	
   logo	
   
   function usage()
   {	printf "\nKernMan is a script written for the purpuse of simplyfying Kernel Managenemt.
   	
   	Select the option 'List' to display all installed kernels/ Se;ect the option 'Purge' to display 
   	all kernels that can be removed and subsequently do so"}
   	
   	
   	
   PS3='Please enter your choice: '
   options=("Usage" "List" "Purge" "Quit")
   select opt in "${options[@]}"
   do
       case $opt in
           "Usage")
   	    usage
               ;;
           "List")
               `dpkg -l linux-image-\* | grep ^ii`
               ;;
           "Purge")
               kernelver=$(uname -r | sed -r 's/-[a-z]+//')
               dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve $kernelver
               
               printf "\nThese items will be deleted.\n"
               read -p 'Continue? Y/n ' choice
               
               if [[ $choice == "y" ]]; then
   		sudo apt-get purge $(dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve "$(uname -r | sed -r 's/-[a-z]+//')")
   	    else
   		echo "Aborted"
   		break
   		exit 1
   	    fi
               ;;
           "Quit")
               break
               ;;
           *) echo invalid option;;
       esac
   done
   

   
   
   Why then do i get an unexpected end of file error?

   That's funny, but not really helpful.

   If your closing brace for a function is on the same line as a command it needs to be preceded by a semicolon. Personally I'd just move the closing braces for logo and usage to the next line.

   also since `foo()` is not call syntax the keyword function isn't necessary, you generally choose between `function foo {...` and `foo() {...`, the former is arguably better style since there are no named arguments in bash the parens were mostly added just to make C programmers feel more at home.
