OK, a REAL Linux question... ; -) Ineeda"one-liner" (because I am lazy)

[Bob Elzer]

Well it sounds like from your first post this was a one time deal.

>>I want to find the file that resembles most closely the one I have at
hand.

"most closely" implies, I don't know what it looks like.

One Liner means just that.

Is this an on going process, do you have a starting file to work with ? Your
first message said you needed to find two near similar files somewhere in a
directory tree.

I'm not picking on you, but I used to tell my users, If you ask Santa for a
toy soldier and you get a green plastic army man, don't be upset because you
really wanted a G.I. Joe doll.

Is what changes in the file the same line each time ?

Can you give us a real example of one of these ?

Thanks.
Time won't work.
These files are coming from a repository and they all have the same
date/time.

I know what I want to find.
I want to find the file that resembles most closely the one I have at hand.
It's called a "Fuzzy" search. 

One approach would be to fire up a loop to compare every file to another one
ignoring white-spaces, log the resulted diff files, choose the smallest
results at the end of the run (after you define "smallest") and then use
some sort of "Fuzzy algorithm" to pick the finalists.
The final decision is hand picked.
Far from a "one-liner"...   :)
Thanks!   :)
