Searching is easy:

grep pattern file        use grep -i for case insensitive searching

As for removing: a bit more subtle. If you know your string is unique, you
can do

cat orig_file | grep -v pattern > new_file

grep -v will strip the pattern you specify, but it will strip the entire
line ... for
more contrived things (just a word on a line) use vi (or any other text
editor)
or you'd have to write some short awk/perl scripts ...

All of this should work on any UNIX type system ...
