Shell Script to replace tokens in multiple files
I have multiple script files that I have created, that allow me to simply replace a few tokens at the top of the file, and then not have to go through the actual script and change anything. I have about 10 of them, but I was hoping to find a way to write a small script that would allow me to input what value I want those tokens to hold, and then run that script, and it would go through all the scripts I have and replace the tokens with the values I input in to the first script.

Not sure if I explained it very well, but here's an example.

replaceScript.sh -

serverScript1.sh
serverScript2.sh
serverScript3.sh

when I run replaceScript.sh, I'd like to be able to input, say, 5 variables(var1-var2-...var5), then the replaceScript.sh will go through and replace those same variables that have been set in serverScript1-3, with the values I input in to the replaceScript.sh

MAKESH(1)                                                     General Commands Manual                                                    MAKESH(1)

NAME

       makeSH - a .SH script maker

SYNOPSIS

       makeSH files

DESCRIPTION

       MakeSH  examines  one or more scripts and produces a .SH file that, when run under sh, will produce the original script.  The .SH script so
       produced has two sections containing code destined for the output.  The first section has variable substitutions performed  on  it  (taking
       values  from  config.sh), while the second section does not.  MakeSH does not know which variables you want to have substituted, so it puts
       the whole script into the second section.  It's up to you to insert any variable substitutions in the first section for any values you want
       from config.sh.

       You  should  run  makeSH from within your top-level directory and use the relative path to the file as an argument, so that the "Extracting
       ..." line printed while running the produced .SH file later on will give that same path.

BUGS

       It could assume that variables from metaconfig's Glossary need to be initialized in the first section, but I'm too lazy to make it do that.
