You have single quote within double quote, does not work. cmd1="$( sed -n '1p' cmd)"

Space after the $ gives problem disk1="$ (sed -n '1p' disk)"
This have one back ticks not two comm="$cmd1 $disk1"`

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. BUGS, IDEAS, FEEDBACK This document, will undoubtedly contain bugs and other problems.
