Guys i need an idea for one logic..in shell scripting am struggling with a logic...So the thing is... i need to search for a word in a huge log file and i need to continue to print few more lines from that line and the consecutive line has to end when it finds the line with date..because i know only the date which is first field...

udm_find

UDM_FIND(3)								 1							       UDM_FIND(3)

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.
