Yea .. good catch .. I forgot to type 'xargs' before grep ..
This did the right thing and found all the relevant files.
I probably did not mention that the 'bar' can appear anywhere in the foo command call and there is no specific pattern. Will I be able use wildcards in the pattern matching string for 's/' and say inside the foo command change all occurrences of bar? I tried using foo\(.*)bar pattern but i keep getting the signal 13 error from grep or unmatched ) error. I am surely missing something obvious here. pointers?

I went a step further now ... I tried the following:
It matched the proper pattern but instead of replacing the existing contents and only replacing bar with bar1, it replaced the whole thing with 'foo.*?bar1' which is not what I wanted.
should be changed to
The number of blah's varies widely. How do I make it replace the pattern properly?

replace
REPLACE(1) MySQL Database System REPLACE(1)NAME
replace - a string-replacement utility
SYNOPSIS
replace arguments
DESCRIPTION
The replace utility program changes strings in place in files or on the standard input.
Invoke replace in one of the following ways:
shell> replace from to [from to] ... -- file_name [file_name] ...
shell> replace from to [from to] ... < file_name
from represents a string to look for and to represents its replacement. There can be one or more pairs of strings.
Use the -- option to indicate where the string-replacement list ends and the file names begin. In this case, any file named on the command
line is modified in place, so you may want to make a copy of the original before converting it. replace prints a message indicating which
of the input files it actually modifies.
If the -- option is not given, replace reads the standard input and writes to the standard output.
replace uses a finite state machine to match longer strings first. It can be used to swap strings. For example, the following command swaps
a and b in the given files, file1 and file2:
shell> replace a b b a -- file1 file2 ...
The replace program is used by msql2mysql. See msql2mysql(1).
replace supports the following options.
o -?, -I
Display a help message and exit.
o -#debug_options
Enable debugging.
o -s
Silent mode. Print less information what the program does.
o -v
Verbose mode. Print more information about what the program does.
o -V
Display version information and exit.
