Replace string in a file w/ a variable value
I am trying to replace the default home page for several mac user accounts, I wrote a script that will hunt the files down and replace them with a pre-configured set. The problem I am having is that the download destination path for the browser is hard coded into a .plist (text config file) file along with the homepage. The issue is that if I replace this file with a pre-configured version the homepage is changed successfully but the download location is then wrong and the browser won't be able to download anything.

the download path originally is something like /Users/rob/Desktop
the altered one is something like /Users/sample/Desktop

Because the /Users/sample/Desktop doesn't match the user I am replacing files for, there is a problem.

So I would like to set the location in the pre-configured file to something like /Users/[PATTERN//PATTERN]/Desktop and have the script open the text file, look for the pattern and replace it with the value of a variable called $USER_NAME which I already have holding the proper user name earlier in the script.

How can I have the script look inside the .plist file, find the pattern and replace it with a variable value?

Thanks,
Rob

git-web--browse

GIT-WEB--BROWSE(1)						    Git Manual							GIT-WEB--BROWSE(1)

NAME

       git-web--browse - git helper script to launch a web browser

SYNOPSIS

       git web--browse [OPTIONS] URL/FILE ...

DESCRIPTION

       This script tries, as much as possible, to display the URLs and FILEs that are passed as arguments, as HTML pages in new tabs on an already
       opened web browser.

       The following browsers (or commands) are currently supported:

       o   firefox (this is the default under X Window when not using KDE)

       o   iceweasel

       o   seamonkey

       o   iceape

       o   chromium (also supported as chromium-browser)

       o   google-chrome (also supported as chrome)

       o   konqueror (this is the default under KDE, see Note about konqueror below)

       o   opera

       o   w3m (this is the default outside graphical environments)

       o   elinks

       o   links

       o   lynx

       o   dillo

       o   open (this is the default under Mac OS X GUI)

       o   start (this is the default under MinGW)

       Custom commands may also be specified.

OPTIONS

       -b <browser>, --browser=<browser>
	   Use the specified browser. It must be in the list of supported browsers.

       -t <browser>, --tool=<browser>
	   Same as above.

       -c <conf.var>, --config=<conf.var>
	   CONF.VAR is looked up in the git config files. If it's set, then its value specifies the browser that should be used.

CONFIGURATION VARIABLES

   CONF.VAR (from -c option) and web.browser
       The web browser can be specified using a configuration variable passed with the -c (or --config) command line option, or the web.browser
       configuration variable if the former is not used.

   browser.<tool>.path
       You can explicitly provide a full path to your preferred browser by setting the configuration variable browser.<tool>.path. For example,
       you can configure the absolute path to firefox by setting browser.firefox.path. Otherwise, git web--browse assumes the tool is available in
       PATH.

   browser.<tool>.cmd
       When the browser, specified by options or configuration variables, is not among the supported ones, then the corresponding
       browser.<tool>.cmd configuration variable will be looked up. If this variable exists then git web--browse will treat the specified tool as
       a custom command and will use a shell eval to run the command with the URLs passed as arguments.

NOTE ABOUT KONQUEROR

       When konqueror is specified by a command line option or a configuration variable, we launch kfmclient to try to open the HTML man page on
       an already opened konqueror in a new tab if possible.

       For consistency, we also try such a trick if browser.konqueror.path is set to something like A_PATH_TO/konqueror. That means we will try to
       launch A_PATH_TO/kfmclient instead.

       If you really want to use konqueror, then you can use something like the following:

		   [web]
			   browser = konq

		   [browser "konq"]
			   cmd = A_PATH_TO/konqueror

   Note about git-config --global
       Note that these configuration variables should probably be set using the --global flag, for example like this:

	   $ git config --global web.browser firefox

       as they are probably more user specific than repository specific. See git-config(1) for more information about this.
