Full Discussion: Find EXACT word in files, just the word: no prefix, no suffix, no 'similar', just the word
Top Forums UNIX for Dummies Questions & Answers Find EXACT word in files, just the word: no prefix, no suffix, no 'similar', just the word Post 302613981 by rbatte1 on Wednesday 28th of March 2012 05:42:40 AM

Can you confirm the content of your control file please. i suspect that you have something like the following (using ^ to mark start of line and $ to mark the end):-
Code:
^Word1$
^Fred$
^Sun$
^Choc$

... so what you are matching is the string listed on each line (e.g. Sun) so this will match anywhere it finds Sun, e.g. Sunny, Sunday, WhitSun etc. What you might need is a tweak in your control file. What are the delimiters in the file you are searching? If they are spaces, then you need to generate you control file with spaces at the beginning and end of each line, so (using same markers):-
Code:
^ Word1 $
^ Fred $
^ Sun $
^ Choc $

That way, it will match the whole string including the spaces before and after. Of course you then have the problem that some records you want may only have a space before or after, so you might have to get a little more inventive.

Does this help?


If you already have a large control file to search with, then using vi you can enter the following commands to insert a space at the beggining and end of each line:-
Code:
:%s /^/ /
:%s /$/ /


I hope that this (and the explanation) helps, but feel free to write back with more examples where it doesn't quite work.
