I want to build cross reference on certain lines in files. I can
extract those lines into a file, say in format
Now, how do I build cross reference?
For example, if I have
file1, one two three red
file2, four five
file3, red blue yellow
file4, blue one
Then, cross reference for "red" should give me first line (file1) and
3rd line (file3). And, cross reference for "red one" should give me
only the first line (file1). I guess I can do
fgrep -e red
fgrep -e red | fgrep -e one
Is there a program, similar to "updatedb" and "slocate"?
