I have a file that goes like this:
I need to grep the lines between pattern 1 and pattern 2 and not the lines following pattern 2. Cannot use grep -A(num), as there are varying number of lines following pattern 1. Also, used awk one-liners, but results are erroneous.
Awk varying patterns to different file?

What I want to do is when the records have identical $3 i.e. same gene:blabla, I want to put them in a file with $3.out (P.S. along with the lines below it) I tried grepping out $3 first separately onto a file, and then taking each line in that file as a pattern and pulling out records using awk. Somehow I faced probs with pulling out onto $3.out
I am trying to compare a list of patterns from one file and grep them against another file and print out only the unique patterns. Unfortunately these files are so large that they have yet to run to completion. Here's the command that I used:
Code: grep -L -f file_one.txt file_two.txt > output.output Here's some example data:
Code:
>FQ4HLCS01BMR4N
>FQ4HLCS01BZNV6
>FQ4HLCS01B40PB
>FQ4HLCS01BT43K
>FQ4HLCS01CB736
>FQ4HLCS01BU3UM
>FQ4HLCS01BBIFQ
how to increase efficiency or use another command?
I have to write a script which would search the IP adesseses in a given directory.
Below is my command.
Code:
grep -HwrnI --exclude=*.log '[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}' *|grep -v '/.svn/'
I have to exclude the following from search resluts.
1. Comments
a. Can be starting with /, * or #...
b. Cane be between a line
EX: some text... #comment1
I want to traverse a directory and get a list of files that contain a set of patterns. I assumed I could use grep for this, but I having trouble getting grep to only return files that match ALL patterns. Here's what I've come up with so far:
Code:
grep --recursive --file=searchpatterns.txt --files-with-matches somedirectory/*
However, this gives me a list of files that match ANY of the patterns in the searchpatterns.txt file. I want to match ALL of the patterns. I've looked through the man page, but can't find anything that allows me to change the "OR" to "AND" for multiple patterns.
I am interested in using the grep method in the shell of my CentOS machine to obtain patterns from a file and use them to search through another file and highlight the patterns found. For example:
pattern file:
one
two
three
test file:
AAAAAAAAAAAAAAAAAAAAAoneAAAAAAAAAAAAAAAAthreeAAAAAAAAAAAA
I have a file that I need to scan and output data between Number and End containing string 123.
Number 1:
6
7
123
1
End
I am trying to delete any blank lines within two patterns e.g.
Address: 53 HIGH STREET Cred Id :
MYTOWN
MYCOUNTY
MM12 6MM
Pay Method : Crossed Cheque
The start of my pattern is "Cred Id" and the end is "Pay Method" and I want to delete the blank lines between county and post code. I did find the code below but it doesn't seem to change anything:
sed -ne '/Cred Id/,/Pay Method/!bp' -e '/^$/b' -e -e p ll.out
I can get it to print just the range I'm interested in by doing sed -ne '/Cred Id/,/Pay Method/p'.
I know how to use grep to output a line that matches a string. But what if I also want to output one line above every line containing a matching string, how do I do that?
View 1 Replies View RelatedDoes anyone know why something like:
echo lowercase | grep [A-Z]
Would still return the lowercase line even tho there is no match?
Using --color will show there is no match but the line is still returned.

I have a large file in which each line has three or more blank-delimited words. I'd like to code a grep to keep only those lines which have the letter M in the last word. the M (if present) will be the first character in the last word.

I have a text file and i want to grep the word "interface" and 10 lines following it. I think there was some switch like grep -A or something ?
I have a list of words that I want to grep in many files to see which ones have it and which ones dont. in the text file I have all the words listed line by line, ex: list.txt:
check
try this
word1
word2
open space
list ..
I want to grep each line one by one. like I want it to
grep "check" *.log
grep "try this" *.log
grep "word1" *.log .. etc how can I do this?
and maybe write the output to a file.
I have some big files of logs that contain errors printed by an app. They are most of the time relevant, however most of them are similar. So i figured i could check what happened between a time interval with a find.
Im using this one
Code:
And I get an output similar to this one.
Code:
Is there a way to condensate the output lines to get only one or two, indicating the start and last occurrence of a block? Or I need to create a program to do so?
Because right now I get thousands of similar lines, but when I'm scrolling through them i sometimes miss relevant information that i would've otherwise noted if it wasn't all that spammy.
So For example I run this command:
Code:
But want to gerp / cut it in such a way that it only displays
Code:
Now the thing is that these 3 lines are not static.. there can be N number of lines there.. the only thing is that I want the command / output NOT to display the first line but the rest of the n lines ..
I have a dataset (see example below) that I would like to go through and copy all lines containing a certain string ("LGIG") plus the line immediately following that line to a new file. I have no problem grepping lines containing the string LGIG but I'm lost how to translate that to line number and shift up one line number for each instance of that string.

I need to grep a pattern which can be present in one line or could be split in 2 lines.Normal grep wont work in this case. Can anyone please help on this?There are 100's of files in which i need to search for this pattern so time is also a constrain.

i have a problem about deleting a line from a text file which contains two specific patterns. i am using "sed -i "/$name/ d" peop.txt" but i must use one more variable which is surname.
"
burak:ak:3242:2342:dsa@a.com
gokhan:an:432:4234:da@a.com
"
and this is the code of text file. and the second question when i use "/$name/ d" it deletes not only the names which are macthing with $name but also all words that contain $name. so how can i fix these problems_?
I have a file with joker character patterns:
./include/*
./src/*
etc.
From the current directory I would like to recursively get the list of files that do not match these patterns.
I'm trying to use sed to search for a certain 'primary' pattern that may exist on several lines, with each primary pattern followed by an --unknown-- number of 'secondary' patterns.The lines containing the pattern start with: test(header_name)On that same line is an arbitrary number of strings that come after it.I want to move those strings over to their own lines so that they each are preceded by their own test(header_name).e.g. Original file (mytest.txt):
apples
test("Type1", "hat", "cat", "dog", "house");
bananas

I want to replace a pattern with other pattern in a textfile. But there are two same patterns,but I need two change only the second occurence. EG:

Now I want to change aaaa=x into some other entry.
In Midnight Commander, is it possible to exclude some directories/patterns/... when doing search? (M-?) I'm specifically interested in skipping the .hg subdirectory.
View 1 Replies View RelatedI occasionally need to connect my laptop to different networks. I have an account on each of the machines, but as they are not coordinated, the UID of my account is different on each machine. Example
Machine.........Account UID
Laptop..............501
Server 1............526
Server 2............517
When I connect to the server, I need to have access to my files and directories present on both that server and my laptop - both read and write. There is no problem getting exports setup, but how to I setup my connections such that I connect using the proper UID - or is there another mechanism to do this?I haven't done that much work with NFS, but I'm assuming this has to have been done
I've come across an unusual requirement for a service in my Ubuntu system.Simply put, I need to find a way to search for all instances of a term in a file, delete lines containing containing that term, and delete four lines below each instance of that term. ither that, or copy the entirety of a file to a new file and skip over all lines containing the term plus four below it.This sounds kinda weird, I know. Without going too far into detail, I either have to change the logfile format for a server I'm running which is a huge pain in the butt, or I can just run a script to edit an HTML report generated from said logs. (Said report is really just for managers to peruse, and I like my log format, so I'm pursuing option 2.)
View 4 Replies View RelatedI noticed that one DVD I encoded to ogg (vorbis) resulted in files with varying volume levels (some files have sound much softer than others... and the original DVD is not like that). I wonder if it's mplayer or oggenc's fault. I do it like this (suppose):
Code:
for i in 01 02 03 04 05 ; do mplayer-vc null -vo null -ao pcm:filename=$i.wav dvd:// -title $i-$i; oggenc $i.wav $i.ogg; rm $i.wav; done
I'm doing it by memory so I could have a mistkate or two in the sequence of commands but the idea is very simple
- Output the sound to a wav file using mplayer
- Encode it with oggenc
- Delete the wav file.
Why is the result having varying volume levels?
I need to kind of grep within grep. My input file would be something like:

I remember using some dos program that would scan text files for particular words/patterns. It had an ncurses-like interface and if I'm not wrong its name was "Concord". Is there anything like that on linux? The main functionality was as follows:
1. support for regular expressions
2. print lines containing a particular word or pattern (highlighting it) and printing the surrounding lines.
3. print lines containing a particular word or pattern only if another pattern occurs within N words to the left/right.
The second point is easy to achieve in grep. The 3rd one could be done in awk. The problem is that as much fun as it would be to put it all together and embellish with some nice ncurses interface(eg. with dialog), I don't want to reinvent the wheel. Besides, I have just relocated and have been waiting for my phone line welcome pack for almost 2 weeks now (ie. no internet apart from work and mobile phone), which makes it difficult for me to get anything done.
