highly specific search and replace for a large number of files
hey guys,

I have a directory with about 600 files. I need to find a specific word inside a command and replace only that instance of the word in many files. For example, lets say I have a command called 'foo' in many files. One of the input arguments of the 'foo' call is 'bar'. The word 'bar' many occur in many instances in a file but I want to replace only the 'bar' string inside the foo command call with bar1. I tried the following:
Code:
find . -type f -name *.c  | grep -l foo | xargs perl -ie "s/bar/bar1/g"

This finds all files with the foo command call but replaces all instances of bar with bar1 in those files. I am not sure how to make more specific and make it replace only the foo(bar) instance.

Thanks in advance !

NAME

       sagasu - GNOME tool to find strings in multiple files

SYNOPSIS

       sagasu [string [dir]]

DESCRIPTION

       sagasu  is  a  GNOME  tool to find strings in a set of files.  The user specifies the search directory and the set of files to be searched.
       Double-clicking on a search result launches a user command that can for example load the file in an editor at the  appropriate  line.   The
       search can recurse into subdirectories and can optionally ignore CVS directories.

       Two  optional  command-line arguments can be given: the first is the initial search string and the second is the directory whose files will
       be searched.  If only one argument is given, it is taken as the search string.  No search is actually started, but the  appropriate  fields
       are initialized.  Any subsequent arguments are ignored.

       More documentation is available through the application's Help menu.

BUGS

       The files to be searches are still assumed to be in Latin-1, not in UTF-8.  The same goes for the command-line arguments and  the  terminal
       to which Sagasu is connected, if applicable.

HISTORY

       Sagasu is a Japanese word that means "to search."
