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 302616229 by chicchan on Friday 30th of March 2012 04:23:20 PM

Bug Thank you !!!

First of all, thank you all for your answers.Smilie

My OS is ubuntu 11.10.

I have a friend that is trying the same thing. In his computer the same command line works fine.

My control file does not have the ^ and $. Maybe I should add those to each line. My control looks like this (but much longer):

NGO2105
NGO1081
NGO2156
NGO2158


And I'm trying to look for those identification numbers in files that look like this (but longer):

B0C5G9_ACAM1 B0C5G9 158335687 AMAR329726:AM1_2537-MONOMER null null null 5681349 CP000828_GR null HBG284974 IPR009915 amr:AM1_2537 null HPLMLGF null null null null null PF07298 null CLSK872158 null null YP_001516859.1 null null null null CP000828:ABW27545.1 AM1_2537


So, sometimes I find things like NGO1081.1 and that is an incorrect value for me.

I have other type of files in which I'm searching for the identification numbers, but I think if it works with one it works with others.

Anyway, I found the problem doing some 'hello world'-like tests. Where my control file was like:

NGO2105
NGO1081


And the file I was searching in was like:

dghsahgjgdsNGO2105
NGO2105ghdshf
NGO2105
asghdfNGO2105dsfjh
(NGO2105)
NGO1081
NGO21


Then the output file was like:

dghsahgjgdsNGO2105
NGO2105ghdshf
NGO2105
asghdfNGO2105dsfjh
(NGO2105)


I was doing other tests right know, following several of your advises. And turned out that grep is doing it fine. I took some precautions like deleting hidden files (that were making some noise). The last command line that I used and work fine was:

Code:
fgrep -wf Id -h searchFiles/* >> outputFile

I don't know if the -f was necessary but it works fine with it.

Thank you for all your replies.Smilie

udm_find - Perform search

SYNOPSIS
resource udm_find (resource $agent, string $query) DESCRIPTION
Performs a search. The search itself. The first argument - session, the next one - query itself. To find something just type words you want to find and press SUBMIT button. For example, "mysql odbc". You should not use quotes " in query, they are written here only to divide a query from other text. mnoGoSearch will find all documents that contain word "mysql" and/or word "odbc". Best documents having bigger weights will be dis- played first. If you use search mode ALL, search will return documents that contain both (or more) words you entered. In case you use mode ANY, the search will return list of documents that contain any of the words you entered. If you want more advanced results you may use query language. You should select "bool" match mode in the search from. PARAMETERS
o $agent - A link to Agent, received after call to udm_alloc_agent(3). o $query - mnoGoSearch understands the following boolean operators: & - logical AND. For example, "mysql & odbc". mnoGoSearch will find any URLs that contain both "mysql" and "odbc". | - logical OR. For example "mysql|odbc". mnoGoSearch will find any URLs, that contain word "mysql" or word "odbc". ~ - logical NOT. For example "mysql & ~odbc". mnoGoSearch will find URLs that contain word "mysql" and do not contain word "odbc" at the same time. Note that ~ just excludes given word from results. Query "~odbc" will find nothing! () - group command to compose more complex queries. For example "(mysql | msql) & ~postgres". Query language is simple and powerful at the same time. Just consider query as usual boolean expression. RETURN VALUES
Returns a result link identifier on success or FALSE on failure. PHP Documentation Group UDM_FIND(3)
