I have a script that generates a new template script. I have no problems passing variables from the generating script to the template script by prefixing said variables with \, i.e. AA1="\$LINENO" However, when I attempt to pass the following variable it is expanded regardless of any restriction that I use to restrict the expansion:
message=`cat /error_messages/test_msg.txt`

The template script is expanded to:
message=This is a test of an error message.

The result I am looking for is:
message=`cat /error_messages/test_msg.txt`

Thank you for your assistance.

I'm not sure I understand the problem? Why can't you just quote it:

Can you provide more detail?

I have tried message='`cat /error_messages/test_msg.txt`' and get the following result:
message='This is a test of an email error message. ', the variable "message" is an expansion of the path.

Since the code is within a function I tested it outside of the function and the results are the same.

The following code does not result in expansion: message=/error_messages/test_msg.txt. So the problem as I see it, is when the code is back quoted and cat is inserted as a command the script that generating the template code executes cat. I believe what is required is to isolate `cat ......` so that the generating script does not execute cat. I use kate as an editor. I can can see that cat is being treated as a command in the generating script.

Thank you for your assistance.

have you tried:
Alternatively, please can you provide a larger piece of sample code so that we can try things out.

Disillusionist,

Your code resolved the problems, I knew that there was a solution just could not figure it out.

Thank you!!!

Just to have that sorted. everythign between ` and ` is run in a subshell. ` IS NO QOTATION in bash. Use ' or " to quote things.
' takes everything between two of them as it is. " allows for interpretation like $variable.

P.S
to differ between ` and ' use $(your command to run). This does the same like `your command to run`

This explanation is the best that I have encountered. An example or two might help others better understand the concept.

Okay but just some quick ones I'am having migraine headache For further explanations look at :

Quotation in shell (BASH)
There are two kinds of quotation marks one is ' and the other is " They should always come in pairs say start of quotation and end of quotation else the shell will not be happy and provide a < as a prompt (after hitting enter).
examples:
'example'
"example"

Diffrence between the two is how they esacpe special shell characters like $ * ?. ' escapes everything. So no evaluation is done. With " everything will get expanded
example:
prints
prints
Prepare to not mix up ` and '!
` is the start of shell expansion. Everything between `some command` will be run in a subshell. If you want that better use $(somecommand) this is easier to distinguish.

Last one is \ this tells the shell to escape the following character so that it's not interpreted by the shell.
example
will print
Now of to bed or to
