Hi again,
But how does this allow me to say "Search for foo and replace it with bar.
if you get to the end without finding foo add this line (which incidentally
is the full line including foo and bar)
Example
File contains
foo1 = bar1
foo2 = bar2
foo4 = bar4
search for foo1 and replace bar* with bar1-1
if you don't find it add it
search for foo2 and replace bar* with bar2-2
if you don't find it add it
search for foo3 and replace bar* with bar3-3
if you don't find it add it
search for foo4 and replace bar* with bar4-4
if you don't find it add it.
The output should be
foo1 = bar1-1
foo2 = bar2-2
foo3 = bar3-3
foo4 = bar4-4
Any ideas
