[ale] Shell scripting with bash

[Ken Nagorski]

Hi there,

	I have a little problem using bash. I usually use bash for real
simple stuff no more than 3-4 lines of code however I have a script that
lends itself to bash. It's for making boot disks that use lilo. It works
fine except for the part where I call a function. 

	The code is below however, this is what I wanna do. I want to set
it up so that the user enters the kernel they want on the boot disk. If
that doesn't exsist - ask agian. I seem to be having a bit of a problem
making use of functions in bash....

get_kern
{
 echo "Please enter the full path of the kernel you wish to use"
 read kernel
}

if [ -e $kernel ]
 then
  cp $kernel /mnt/floppy/vmlinuz
  lilo -v -C /mnt/floppy/lilo.conf -f /mnt/floppy
  exit 0
 else
  get_kern
fi


	It works the first time I call it from the program but then it
complains if I try to call it agian. Any suggestions. I looked at the bash
programing howto and I couldn't find anything about calling functios cept
the simple little example. I also checked the web. Nothing helped there
either.

Thank you
Ken
