grep problem

[ianicr]

I'm doing a grep on postcodes eg
grep "B2 4" filename
However this gives me results such as AB2 4 and CB2 4. I've looked at the man page and can't see how to match only the string and no extras.
Thanks

If you know that there will always be a comma before the post code then...

grep ",B2 4" filename

...or perhaps you can use grep -w

 

[ianicr]

Yep the ",B2 4" seems to work fine. I've created a pattern file that looks like this:
",B24 "
",B31 "
",B32 "
",B47 "
",B54 "
",B79 9"
",B95 6"
",BA4 4"
",BA8 0"
",BA9 8"
and am trying to do a grep -f patternfile postcodefile but I get no results. However if I do them individually it finds them. Any ideas what the problem could be?

 

[Ygor]

Does the file contain quotes ("&quot ? If so, then try without them.

Try to remove your quote in the patternfile.

tikual

 

[ianicr]

nope. still produces nothing without quotes

What Unix? Can you post a few lines from patternfile, postcodesfile?

 

[ianicr]

I'm using cygwin on winxp
patternfile:
,B24
,B31
,B32
,B47
,B54
postcodefile:
Mr,F,Fram,4 Uppergate,,,,Adeen,,AB10 13A
,F,Kram,96 Little St,,,,Adeen,,AB10 11L
,A,T1aftey,5 Hill,,,,Adeen,,AB0 3JX
,K,Linhadsfl,17 Kene St,,,,Adeen,,AB0 1QN
,T,Boydalonga,32 Kiddlandston Std,,,,Adeen,,AB30 1RT
,C,Abyounish,30 Cremanal Pl,,,,Adeen,,AB24 1RX
,R,Kirkland,2F Cremanal Pl,,,,Adeen,,AB26 17Y
,C,Galling,4e Spring St,,,,Adeen,,CB10 17B

Thanks

In your example lines, none of the patterns matches an enrty in the postcodes. To test it, I changed ,B24 to ,AB24 and it works fine on SCO Openserver 5.0.5. Are you aware of the space characters after the patterns? Do they exist also in the postcodes? What does cygwin manual says about -f ?

 

[ianicr]

Sorry I only cut the top of the file. In the full file there are postcodes. Is it something to do with lf/cr in windoze/unix?

 

[ianicr]

I think it was something to do with CR/LF's in windoze. I've ran it through a lf2cr script and it works fine now. Thanks
