read lines between search pattern
I have a file split something like
01/11/2010:
No of users 100
02/11/2010:
No of users 102
03/11/2010:
No of users 99
...
I want to search the file for a particular date and then extract the following line with the date, something like
02/11/2010 No of users 102
I can grep the date or read the file but now sure how to read the line(s) before the next date?

Hi,
I've written a script to search for an Oracle ORA- error on a log file, print that line and the .trc file associated with it as well as the dateline of when I assumed the error occured. In most it is the first dateline previous to the error.
Unfortunately, this is not a fool proof script.... (2 Replies)

jifty::action::record::search
Jifty::Action::Record::Search(3pm) User Contributed Perl Documentation Jifty::Action::Record::Search(3pm)
NAME
Jifty::Action::Record::Search - Automagic search action
DESCRIPTION
The class is a base class for Jifty::Actions that serve to provide an interface to general searches through Jifty::Record objects. To use
it, subclass it and override the "record_class" method to return the fully qualified name of the model to do searches over.
METHODS
arguments
Remove validators from arguments, as well as ``mandatory'' restrictions. Remove any arguments that render as password fields, or refer to
collections.
Generate additional search arguments for each field based on the following criteria:
"text", "char" or "varchar" fields
Create "field"_contains and "field"_lacks arguments
"date", or "timestamp" fields
Create "field"_before, "field"_after, "field"_since and "field"_until arguments.
"integer", "float", "double", "decimal" or "numeric" fields
Generate "field"_lt, "field"_gt, "field"_le and "field"_ge arguments, as well as a "field"_dwim field that accepts a prefixed
comparison operator in the search value, such as ">100" and "!100".
take_action
Return a collection with the result of the search specified by the given arguments.
We interpret a "undef" argument as SQL "NULL", and ignore empty or non-present arguments.
