Bug Shell script that generates another shell script

If there's a file called example.txt with contents:
Foo
Bar
Baz
Goo

then I need to generate a shell script that has commands to reconstruct example.txt on another machine:

Code:
echo "Foo" >> example.txt
          echo "Bar" >> example.txt
          echo "Baz" >> example.txt
          echo "Goo" >> example.txt

I use for i in * to search a directory and conduct the above operation on every file that's not binary. Suppose i points to example.txt now, as the above example shows. I used sed to extract the contents of the files line by line. The question is how to use the result extracted by sed as the argument of echo?

I tried:
Code:
number=`wc -l < $i`
          count=1
          while [ $count -le $number ]
          do
          tmp=`sed -n "$count,1p" $i`
          echo ' echo "$tmp" >> $i ' >> bundle.sh
          done

Here tmp is the content of each line, but $tmp didn't evaluate in echo.

Actually the purpose of doing so is to transfer a directory containing various files and subdirectories which also contain files to another machine through simple email. Only bundle.sh needs to be transferred. So when the shell script bundle.sh is run on the other machine, the whole directory will be constructed there. I'm writing a script that can generate the bundle.sh script. And of course this needs to be done recursively since there're subdirectories, but ignore it for now. Thanks.

NAME
exit, return, goto - shell built-in functions to enable the execution of the shell to advance beyond its sequence of steps SYNOPSIS
sh exit [n] return [n] csh exit [ ( expr )] goto label ksh *exit [n] *return [n] DESCRIPTION
sh exit will cause the calling shell or shell script to exit with the exit status specified by n. If n is omitted the exit status is that of the last command executed (an EOF will also cause the shell to exit.) return causes a function to exit with the return value specified by n. If n is omitted, the return status is that of the last command exe- cuted. csh exit will cause the calling shell or shell script to exit, either with the value of the status variable or with the value specified by the expression expr. The goto built-in uses a specified label as a search string amongst commands. The shell rewinds its input as much as possible and searches for a line of the form label: possibly preceded by space or tab characters. Execution continues after the indicated line. It is an error to jump to a label that occurs between a while or for built-in command and its corresponding end. ksh exit will cause the calling shell or shell script to exit with the exit status specified by n. The value will be the least significant 8 bits of the specified status. If n is omitted then the exit status is that of the last command executed. When exit occurs when executing a trap, the last command refers to the command that executed before the trap was invoked. An end-of-file will also cause the shell to exit except for a shell which has the ignoreeof option (See set below) turned on. return causes a shell function or '.' script to return to the invoking script with the return status specified by n. The value will be the least significant 8 bits of the specified status. If n is omitted then the return status is that of the last command executed. If return is invoked while not in a function or a '.' script, then it is the same as an exit. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari- able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed. ATTRIBUTES
