shell pattern matching
Hello Members
I am facing a problem regarding pattern matching.please guide me to solve the issue.My requirement is like:
There is table in oracle database, in that table contain columns ,inside the column so many files are there. my requirement is that to search a pattern for example: pattern is "123456" . Write a shell script that search the pattern one by one file(i.e it takes the file one by one from table) . if inside a file pattern doesn't exist then it will redirect this pattern and file name to some other file.
Please give me some idea so that i can move ahead, any help will be highly appreciated.
Thanks
Rakesh

Hi all,
Is Perl included by default in Ubuntu? I'm trying to write a program using as few languages as possible, and since I'm using a few Perl one-liners to do non-greedy matching, it's considered another language, and this is a bad thing.

svk::log::filter::grep
SVK::Log::Filter::Grep(3) User Contributed Perl Documentation SVK::Log::Filter::Grep(3)
SYNOPSIS
SVK::Log::Filter::Grep - search log messages for a given pattern
DESCRIPTION
The Grep filter requires a single Perl pattern (regular expression) as its argument. The pattern is then applied to the svn:log property
of each revision it receives. If the pattern matches, the revision is allowed to continue down the pipeline. If the pattern fails to
match, the pipeline immediately skips to the next revision.
The pattern is applied with the /i modifier (case insensitivity). If you want case-sensitivity or other modifications to the behavior of
your pattern, you must use the "(?imsx-imsx)" extended pattern (see "perldoc perlre" for details). For example, to search for log messages
that match exactly the characters "foo" you might use
svk log --filter "grep (?-i)foo"
However, to search for "foo" without regards for case, one might try
svk log --filter "grep foo"
The result of any capturing parentheses inside the pattern are not available. If demand dictates, the Grep filter could be modified to
place the captured value somewhere in the stash for other filters to access.
If the pattern contains a pipe character ('|'), it must be escaped by preceding it with a '' character. Otherwise, the portion of the
pattern after the pipe character is interpreted as the name of a log filter.
STASH
/PROPERTY MODIFICATIONS
Grep leaves all properties and the stash intact.
