There are no labels and jumps in shell. The best you can do is use conditionals.

foo() {
commands
}

bar() {
commands
}

if [ $somecondition = 1 ]; then
foo
else
bar
fi

Here is some good documentation on bash (which is probably the shell
you're using):

As Dan already pointed out, there are no direct replacements for labels 
and goto.  However, I think that you will find functions and conditional 
statements much more powerful than the goto command once you use them a 
few times.  Here is your example.bat in example.sh:

=
#!/bin/sh
# Begin /home/dj/bin/example.sh

# this is a function for the label you used above
end(){
 some ending command
 # the exit command takes an optional return
 # value to pass back to the shell errorlevel
 # in DOS is $? in shell (the return vlaue)
 exit 0
}

# This is where your script actually starts
some command
some command
# if the previous command was successful then end
# or continue on to the next command
if [ $? == 0 ]
then
 end
fi

another command
another command
end

# End /home/dj/bin/example.sh
=

Feel free to throw a couple more small examples this way if you need 
more help with it.
