enhanced substitution

Dear

I have a problem on which I turn araound since hours.
Hope you could help me.

I have a bash script, which activates with "nohup ./script2 params & " several subscripts.

In my main script, I have set lot's of variables, which I would pass into script 2.

My idea is now to create a file with parameter content, like:
envCode="X"
envPath="../temp/X"
...

Then I just pass over this parameter path & filename and execute it then in the subscripts.

So far this works well.

Here my questions:
1) Is there a possibility to create the parameter file more dynamically, e.g. by all parameters defined in main script when parameter file is created ? (like env but for script variables only..)

2) When I have a list of variable names I want to pass, how could I dynamically fill the parameter file.
E.g.

Code:

cat my_file_with_parameternames.txt
  envCode
  envPath

echo $envCode
  X

echo $envPath
  ../temp/X

for k in `cat my_file_with_parameternames.txt`
do
    echo $k=<value of $k variable>"  >> my_parameter_file.sh
done

cat my_parameter_file.sh
  envCode=X
  envPath=../temp/X

Maybe it's not the first time this question is asked, but to be honest, I'm google since hours... Most probably I do not know the correct words to search for ;-(

Any help would be great.

many thanks in advance
Wolfgang

gzexe

GZEXE(1)						      General Commands Manual							  GZEXE(1)

NAME

       gzexe - compress executable files in place

SYNOPSIS

       gzexe [ name ...  ]

DESCRIPTION

       The  gzexe  utility  allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
       penalty in performance).  For example if you execute ``gzexe /bin/cat'' it will create the following two files:
	   -r-xr-xr-x  1 root  bin   9644 Feb 11 11:16 /bin/cat
	   -r-xr-xr-x  1 bin   bin  24576 Nov 23 13:21 /bin/cat~
       /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file.  You can remove /bin/cat~ once  you  are	sure  that
       /bin/cat works properly.

       This utility is most useful on systems with very small disks.

OPTIONS

       -d     Decompress the given executables instead of compressing them.

SEE ALSO

       gzip(1), gznew(1), gzmore(1), gzcmp(1), gzforce(1)

CAVEATS

       The  compressed	executable  is a shell script. This may create some security holes. In particular, the compressed executable relies on the
       PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep).

BUGS

       gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually  in  some  cases,
       using chmod or chown.
