quoting question
hi guys, i have a question related to quoting but i am not sure how to formulate it...

lets say we want to simulate the following shell actions
Code:
cd ~/project-dir
ctags /home/work/folder1/*.sh  /home/work/folder2/*.sh  /home/work/folder3/*.sh

so i make the following script

buidtags.sh
Code:
directory="~/project-dir"
file_locations="/home/work/folder1/*.sh  /home/work/folder2/*.sh  /home/work/folder3/*.sh"

ctags_command=ctags "$file_locations"

(cd "$directory" && $ctags_command )

but it doesn't work...
i think the reason is that it skips file globbing, and considers *.sh to be a file, that (of course) can't be found! How can i make file globbing and double quotes coexist? in other words how can i make this example work?

thanks in advance for your time,
nicolas

PS: in quoting as a reference i use chap7 from "learning the bash shell 3rd edition" but i am relatively new to shell scripting.Is there any other good reference for bash?

NAME

       page_util_quote - page character quoting utilities

SYNOPSIS

       package require page::util::quote  ?0.1?

       package require snit

       ::page::util::quote::unquote char

       ::page::util::quote::quote'tcl char

       ::page::util::quote::quote'tclstr char

       ::page::util::quote::quote'tclcom char

_________________________________________________________________

DESCRIPTION

       This package provides a few utility commands to convert characters into various forms.

API

       ::page::util::quote::unquote char
	      A  character,  as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
	      their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the  result
	      of the command.

       ::page::util::quote::quote'tcl char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
	      regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.

       ::page::util::quote::quote'tclstr char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl  parser  and
	      will generate a human readable representation of the character in question.  The string is returned as the result of this command.

	      The  string  does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
	      with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.

       ::page::util::quote::quote'tclcom char
	      This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser  when
	      used within a Tcl comment. The string is returned as the result of this command.
