Programming :: Sed Regex Get Multiple String Match In Array?
Apr 8, 2011I have a sed match that matches for certain string of a regex expression:
Code:
tname=$(echo "$contents" | sed -n 'some pattern')
How do I match for multiple strings in the $contents and return them as an array? for example
Code:
contents="this is a text, just to match patterns, here is another text to be matched"
the sed func would be able to recognize both "text"s, but only one is outputted?
Possible to put it in an array? so ${bar[0]} gives one and ${bar[1]} gives another
General :: Emacs - Search And Replace Regex In Multiple Buffers?
Apr 7, 2009I'm fairly comfortable with emacs but I can't seem to find how to do this. I deal with a lot of text files and find myself performing a lot of regular expression replacements to correct the formatting of the text -- or to extract certain tidbits of data from large ugly-looking files.
I know how to perform a regular expression replacement in one buffer at a time. But how do you perform a regular expression search and replace across all open buffers? I have found a method to perform a regex search and replace across a directory by marking files but I need to do it in the open buffers.
Programming :: Perl Regex Not Matching Across Multiple Lines Despite Ms Flags / Fix It?
Aug 16, 2010I have written a regular expression (tested in regexpal and regextester alpha something) with which I want to replace something like code...

Programming :: Find With A Regex Path?
May 5, 2010I'm using bash scripting to find any file that matches a path governed by the following regular expression:
"(monthly|nightly).[0-9]+/home/(user1|user2)/.mailbox/"
to match files like:
monthly.9/home/user1/.mailbox/l23131564
nightly.15/home/user2/.mailbox/cur/6546213
I've tried:
Code:
myRegex="(monthly|nightly).[0-9]+/home/(user1|user2)/.mailbox/"
find ./ -regextype posix-egrep -regex $myRegex
and it just spins and never gives me an answer, even though the file structure isn't that big.
General :: Regex - Using Find To Locate Filenames Before A Certain Date?
Jul 11, 2011I have a ton of files that are timestamped directories. These all look like2011-06-24_13.53.36 // a directory name for june 24th, 1:53:36 pmI have thousands of these directories. I want to do operations on some of the older ones. Let's say I give it a string for date time that matches that exact format, like i'll give it2011-06-25_00.00.00 // june 25th, 12amI want to find all the directories BEFORE my time. So if i give the string for 12am on june 25th, i want to find all the directories before then.If not i can find EVERY directory i have like this and then filter after wards. The created/modified dates are not tied to the actual timestamp im looking for (that would make this easier)

General :: Using Grep With Pattern File And PCRE
Sep 25, 2010I would like to write a newline delimeted rules file using PCREs for use with the grep command. Grep has the option -f to obtain the search pattern from a file, and option -P to search using PCREs. However, these two options do not work together. The -f option only seems to work with fixed string rules.A friend previously helped me get around this limitation somehow, but I can't remember how he did it. I also would like the ability to add comments at the end of each rule in the file.
View 11 Replies View RelatedUbuntu :: Parsing Textfiles And Passing Arguments In Bash To Preserve Tracker-tag Metadata
Sep 3, 2010I'm at the bottom of the bash learning curve, looking up, hoping someone can toss me a line. I need to update tracker on my system but this will erase the metatag database I've been building up over the course of months for the purpose of indexing a news archive. So the solution seems to be, 1) save the output of tracker-tag to a text file for all relevant files within a directory, 2) upgrade tracker (since the version in the Ubuntu repositories is very much out of date) and then 3) use a script to parse the text file and pass appropriate arguments back to tracker-tag to rebuild the database. It sounds as though it ought to be simple enough, but I need a push in the right direction, which hopefully will not be off the cliff. Before I confuse my metaphors any further, here's what the text file looks like.

Sep 3, 2009I have two text file named 1.txt & 2.txt.
1. txt contains 5 laks of mobile number.
2. txt has 60 laks of mob no.
Situation is that I want to find and delete numbers in 2.txt which already in 1.txt. Any perl or bash script or any other way to get the work done.
I tried the following:

echo "***DONE***"
It works well with smaller file but it take very very long time even processing 10 thousand numbers.
Programming :: Awk - Substitution With Parts Of Matched Regular Expression Used?

How would this be possible? Would you have to use sed?

General :: Execute Command Inside First Directory Of Each Matched Result?

It would be something like a "grep -lr 'eth0' *" and "grep -lr 'us' *" but in one time/command, so that I don't have to make a comparison of the 2 list of files resulting from the 2 "grep" commands given higher.
