Imagine
i kissed a girl
Thriller
animals
hallelujah
paint it black
psychosocial
Oi to the world
Zombie Zoo
song that never ends

The part of my script I'm having trouble with is as follows:

Code:
while read title
do
  title=$(echo $title | tr '[A-Z' '[a-z]')
  find /mnt/music -iname "*$title*" >> top10.lst
done < top10song.tm2

I've confirmed that every title in the top10song.tm2 list exists somewhere in /mnt/music. Running /find /mnt/music -iname "*paint it black*" from the command line returns a positive match, for example. But in the script? Nothing.

Also, is there a way to get find to stop after the first match?

Thanks in advance!
Try this:
for title in $(<top10song.tm2)
do
title=$(echo $title | tr '[A-Z' '[a-z]')
find /mnt/music -iname "*$title*" >> top10.lst
done

dh_metainit

DH_METAINIT(1)						User Contributed Perl Documentation					    DH_METAINIT(1)

NAME

       dh_metainit - install metainit files into package build directories

SYNOPSIS

       dh_metainit [debhelper options] [--name=name] [-n] [-o]

DESCRIPTION

       dh_metainit is a debhelper program that is responsible for installing metainit files (for further creation of initscripts via the update-
       metainit facility) into package build directories.

       It also automatically generates the postinst and postrm and prerm commands needed to create the appropriate initscripts for the init system
       employed on the user machine.

       Important: If generated postinst script finds /etc/init.d/ or /etc/default files with the same name as the shipped metainit files, and
       these are conffiles from non-installed packages (probably earlier version of this package) they are removed (or renamed if the user has
       modified them). This works only if the name of the new metainit is the same as the name of the old init.d and default file, otherwise you
       will have to remove these files yourself. See http://wiki.debian.org/DpkgConffileHandling for that.

       If a file named debian/package.metainit exists, then it is installed into etc/metainit/package in the package build directory, with "pack-
       age" replaced by the package name.

OPTIONS

       -n, --noscripts
	   Do not modify postinst/postrm/prerm scripts.

       -o, --onlyscripts
	   Only modify postinst/postrm/prerm scripts, do not actually install any metainit files. May be useful if the init script is shipped
	   and/or installed by upstream in a way that doesn't make it easy to let dh_metainit find it.

       --name=name
	   Install the metainit script using the filename name instead of the default filename, which is the package name. When this parameter is
	   used, dh_metainit looks for and installs files named debian/package.name.metainit, instead of the usual debian/package.init.

       --error-handler=function
	   Call the named shell function if running the init script fails. The function should be provided in the prerm and postinst scripts,
	   before the #DEBHELPER# token.

NOTES

       Note that this command is not idempotent. "dh_clean -k" should be called between invocations of this command. Otherwise, it may cause mul-
       tiple instances of the same text to be added to maintainer scripts.

SEE ALSO

       This program is a part of debhelper.
