General :: Regex To Find Min / Max Length Words In File?
Jan 29, 2011
i am trying to find all 3 and 4-character length words in my file (which is huge and has alot of entries in it, a big fat wordlist!).My attempt with this regular expression (which I thought should work, found something on length search here: [URL]
cat sorted_noapostrophe.txt| grep '.{3,4}'
but it returns no results? Also to find any words starting with 'f' which are between 3 and 5 characters (inclusive) long, how can this be done?

Its my first post in here so please be patient I am trying to use regex in perl script to detect allowed words from the file and then print output to the screen.
As an example : I have text file with orders and returns :
Item2-SKU-2-11.08.2010-online
Item3-SKU-3-11.09.2010-return
Item4-SKU-4-11.09.2010-store
My question: is it possible to make sure that i am ony outputing to the screen orders based on few conditions like Item,order form e.g. online.And is it possible to have multiple matches (Item2 only diplay if ordered online etc)

I have some lines of text and I want to detect words that meet some criteria with sed.
E.g. The line "tetris cat dog test cactus stereotype"
I want to detect the word that contains two (2) ore more t letters. That mean the words tetris, test and stereotype.
The following regex doesn't do the job because it can;t distinguish words very well.
I thinks I have ti incorporate something like [^ ] in the regex but I wasn't successful...

I 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)

I'm trying to use grep to find the words in the dictionary that contain the letters "th" and the letter m.
I tried grep 'th m*.' Desktop/Dictionary/words(Thats where the destined dictionary word document is located)
grep 'th' Desktop/Dictionary/words works but only for the words with th. I have no idea of what expression to use to make it a unionized expression with m

I am looking for this struct messages_sdd_t and I need to search through a lot of *.c files to find it. However, I can't seen to find a match as I want to exclude all the words 'struct' and 'messages_sdd_t'. As I want to search on this only 'struct messages_sdd_t' The reason for this is, as struct is used many times and I keep getting pages or search results. I have been doing this without success:
find . -type f -name '*.c' | xargs grep 'struct messages_sdd_t'
and this
find . -type f -name '*.c' | xargs egrep -w 'struct|messages_sdd_t'

Multiple dirs full of mp3s All strictly encoded with exactly the same parameters (CBR 128kbps, Joint-Stereo, etc) Is it possible to determine the total playing time (to within ~98% accuracy) by some formula based on the total file size? I say ~98% accurate since ID3 tags do consume a small amount of space.

i want to remove words "Max" and "constrained" in a file given below:
Max 0.003745 constrained
Max 0.004549 constrained
Max 0.001689 constrained
[code]....
and further want to replace "Max" by line number so that i can plot the resulting file. i searched in forum, but couldn't do what i wanted to do. e.g. i used
1)grep command
grep -v "Max" inputfile >outputfile
deletes whole line,and hence whole text.
2) sed command
cat inputfile |sed 's/ .{1,12} //g' >outputfile
gives output
0.003745constrained
0.004549constrained
0.001689constrained
[code]....

Example of a duplicate title I have:

<title>Pasta, Pasta Recipe and Pasta Guide</title>
I dont want to replace those words anywhere else in the file except for within the <title>

I have a text file that gets produced at the end of the script being run.
For this example the text file will produce the following:
Quote:
THE COW
THE DOG
THE CAT
THE HORSE
In the script I am using either echo or printf to print on the screen each line and then it is doing a test and produces a good or bad result.
Another example:
Quote:
THE COW -- IS HOME
THE DOG -- IS HOME
Each whitespace between the -- are 5 spaces. How can I get them to be in-line and formatted when it gets to more words, when THE HORSE arrives.
Example:
Quote:
THE COW -- IS HOME
THE DOG -- IS HOME
THE CAT -- IS HOME
THE HORSE -- IS HOME <-- This has only 3 whitespaces but is still formatted.

I'm trying to recover movie files from my TNT receiver hard drive but it corrupts its FAT32 allocation table (crappy cheap device...)
Using dosfsck is useless because the correct file length is the cluster length, not the (shorter) one in the table, and dosfsck only proposes to shorten the file, which I won't do.
Question: how to recover a file using the FAT cluster chain instead of using the stored length in the FAT table?

I've searched everywhere and I can't come up with a good solution. For each line I need to find the average, min, and max. I've seen plenty of solutions where the number of columns is fixed, unfortunately for me these lines can get pretty large. My thought was to read each line individually into an array, loop through the array and find the avg, min, and max that way but i haven't had much luck. I can read each line using a while loop but I'm having trouble with the array part, or perhaps that's not the best solution?

I need to search a text file for a string of numbers which are different lengths, and always are between number=" and " like:
number="1234567890"
number="22390"
I need to grab those numbers and pipe each one to a line in a file. I've already tried something with awk and that didn't seem to work.

I'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.

am trying to find a proper regex to match the two numbers in the following log entry.
Code:

15:08:16.142 ERR [Uniform test code=64469]
Basically the pattern I'm looking for will match the two different numbers spanned across two lines.Thought I need to use multi-line mode as follow but this doesn't match on [URL]...
Code:
/^($[0-9]{5}
[0-9]{5})$/m;

I downloaded three iso-images, 1 dvd-image and 2 cd-images:
openSUSE-11.3-DVD-i586.iso
openSUSE-11.3-GNOME-LiveCD-i686.iso
openSUSE-11.3-KDE4-LiveCD-i686.iso
Being paranoid, I created iso-files from the burnt DVD-R and the two burnt CD-R to verify integrity.
The iso-file of the DVD-R was identical to the downloaded image. Both iso-files created from the CD-R were different in size.
The original size of openSUSE-11.3-KDE4-LiveCD-i686.iso is 719.323.136 Bytes.
I only got 718.938.112 Bytes when recreating an ISO-file from my CD-R.
The CD-R is from Sony. When the length of my ISO-file doesn't correspond to the downloaded one, the checksum file verification doesn't work.

What I am doing is reading the text from a text document and storing all of the text inside of a ArrayList. I then set one of the values of the Arraylist as a string. I want to use regular expressions find out what the first two characters of the String are. if first two characters = "//" then function(); I only care about the first two characters though. If you need any more information, just ask.

I am using Oracle Enterprise Linux version 4 update 7.
Sometimes I have to access large files with thousands of lines in them and I would like to locate a particultar word. e.g.
vi /etc/passwd.
The contents of file passwd are displayed.I want to find a username of joe assuming the passwd file is 2000 lines long.
I would like to use a linux command that will locate joe and highlight in the passwd file as to where word joe is.
Is there a linux command that can do this?

I tried Suse five or six years ago and ran into an issue that was not comfortable to work with so I went back to windows. The problem was open spaces between words was not permitted with my music files. I have transferred all of my CDs and LPs to MP3 and have a tremendous number of them and the Suse of five years ago required I convert a title like Foggy Mountain Special.mp3 into something resembling Foggy_Mountain_Special.mp3
I don't care to convert literally a hundred thousand titles to fit the latter format. Does the current version of Suse allow the use of spaces between the words or is the 'no open space' convention still required?
