General :: Sed: Replace An Unknown Number Of Patterns On The Same Line?
Jul 5, 2011
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
Does any one know what syntax i could use to allow me to replace all instances at the beginning of a line with ones.
Before :
Code: ---------------------------------------------------------------------- Logical device information ---------------------------------------------------------------------- Logical device number 0 Logical device name : RAID1Mirror RAID level : 1 Status of logical device : Optimal
After
Code: ---------------------------------------------------------------------- Logical device information ---------------------------------------------------------------------- Logical device number 0 111Logical device name : RAID1Mirror 1111RAID level : 1 11111Status of logical device : Optimal
i have a problem about deleting a line from a text file which contains two specific patterns. i am using "sed -i "/$name/ d" peop.txt" but i must use one more variable which is surname.
and this is the code of text file. and the second question when i use "/$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 am trying to replace the first number in a string at the end of the line with the word that matches that number. for example i want to replace 546215 to be five-46215. The command that I have tried is
I have a large number of log files, on a linux box, I need to cleanse sensitive data from before sending to a third party. I have used the below script on previous occasions to perform this task, and it has worked brilliantly (script was built with some help from here :-)
However, now one of our departments has sent me a CLIENT_FILE.txt with 425000+ variables! I think I may have hit some internal limit. I have tried splitting the client file into 4 with around 100000 variables in each, this still doesn't work. I'm loathe to keep splitting though as I have 20 directories with up to 190 files in each directory to run through. The more client files I make, the more passes I have to do.
on creating a new perl script which replace IP address from the text file. eg. If in a file, we found any word like 11.222.333.44 then it has to be replaced to XX.XXX.333.44
I want to print the line number with the pattern of the line on a same line using multi-patterns in sed. But i don't know how to do it. For example, I have a file
I tried posting this before and I'm not sure what happened but I don't think it worked, so if it did please forgive the double post.am very very new to centOS and linux in general. I just want to setup a test web server that more closely mirrors our actual web server that is hosted by rackspace. I've installed centOS and tried to setup Apache, PHP and MySQL from a guide on the web using Yum. When I go to localhost in the web browser I'm able to see the default apache page. However when I create a php page it's just blank.When I look at the apache error logs I get this: PHP Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0
I've been searching alot on the internet and I know the issue is permission related, but I don't know how to fix it. I've seen some forum posts that say you need to use the chmod 775 command on the /var/www/html folder.Currently when I do ls -l /var/www/html it returns
-rw------- 1 root root 19 May 5 13:16 index.php -rw------- 1 root root 19 May 5 13:15 index.php~
I'm sure that this isn't correct but like I said I don't know much about how to set permissions or who the owner needs to be. I've done alot of searching and seen similar posts, but no one seems to explain it clearly.
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:
I trying to change a file with hundreds of entries, replacing line with "IP Address Number" for "Host Name", one for another.
this is the original: [IP Address Configuration : "172_17_27_161.SUBNET_U"] IP Address Number = 172.17.27.161Assignment Type = 8Host Name = CAST124Last Used = 1290499294000MAC Address = 1 00 16 35 74 4C 59Client Identifier = 01 00 16 35 74 4C 59and the result desired is: [IP Address Configuration : "172_17_27_161.SUBNET_U"]Host Name = CAST124Assignment Type = 8IP Address Number = 172.17.27.161Last Used = 1290499294000MAC Address = 1 00 16 35 74 4C 59Client Identifier = 01 00 16 35 74 4C 59I know how to change one character by another with sed, but not to change a line for another, because I don't know in which line number it is.
15 for(i = 0; i < N; i++) I want to replace "i" with "test" in the line above,whose line number is 15. When I tried this command :15s/i/test/ Line 15 turned to be this: for(test = 0; i < N; i++) It only replace the first "i",but I want to change all "i" in line 15.
I have a line of text with multiple web links in the line. I'd like to replace the actual links with the text "<web-link>" so I don't accidentally hit them while reading on my iphone. I've tried many versions of the following sed command, sed 's/(http.*)/<web_link>/g', but it simply replaces everything between the first instance of "(http" and the last instance of ")" with <web_link>, or does nothing at all.
Ex: This line has a link to a web page (http://www.webpage.com/file.html) then some more text (extra text) and then another link (http://www.nextwebpage.com.index.html) to a website. $ echo "This line has a link to a web page (http://www.webpage.com/file.html) then some more text (extra text) and then another link (http://www.nextwebpage.com.index.html) to a website." | sed 's/(http.*)/<web_link>/g'
What I get is: This line has a link to a web page <web_link> to a website. What I'd like is: This line has a link to a web page <web_link> then some more text (extra text) and then another link <web_link> to a website. What am I doing wrong with my sed command?
I have a jar, and I need to replace a class in it, at this moment, I can only open it with "archive manager" and then drag and drop the new compiled class into the jar, but I think this is really boring, if I can do with with just a command ?
Hello, I need some help searching through multiple files, finding a line and replacing that line. The line I am searching for is:
password key ******* 1222554
ultimately I want to be able to delete the numbers after the asterisks . my thoughts are to create a script that will search for the line password key ******* and delete it then replace it with password key ******* my files are located in /opt and they are all txt files.
At the moment I have a flat file which is being used by a few people. I want a script to remotely change the file, so I can start logging who is doing what.At this point here is one requirement I am trying to develop. We have text blocks who pretty much look like.I hope this is somewhat clear. I try to find $param for the right $workflow and change that. Can you help me to find $$var3 and change that?
I have large text files with space delimited strings (2-5). The strings can contain "'" or "-". I'd like to replace say the second space with a pipe. What's the best way to go? Using sed I was thinking of this:
I want to know the Perl command to replace a string by pointing the line number. I know how to replace a string without pointing a line number but I am in need to replace only the two matching string in a file
I have a project due for my Intro to C++ class and we are suppose to generate a file listing that will take an input of a C++ source code with .cpp extension and make a copy of it with a .lst extention that will have a line number preceding each and every line.
I am using Vi editor for editing and configuring my file.I am facing a little problem when there is long file like 3000 lines. Normally i use
Code:
:set number
in vi editor to visible my line number.The problem is when i have to go in the top of the file like say line number one I use k for it and to move down I use j which is too much time consuming. How can i jump directly my cursor to line number 2333 or line number 2600.
I can't get sed to actually change the file, clearly there's something basic not working, can anyone point me in the right direction? I know nothing about scripting. Oh yeah, all the directories have spaces which was why so elaborated.
find . -name "*epub" | while read file; do unzip -o "$file" content.opf && mv content.opf content.opf.bak && sed 's/<dc:language>UND</dc:language>/<dc:language xsi:type="dcterms:RFC4646">EN</dc:language>/' < content.opf.bak > content.opf && zip "$file" content.opf && rm -f content.* ; done
anyway i need to take the average of all rows with the same 1st number(key). i.e.
1, 3, 4.66, 5.66, 5 2, 3.5, 4.5, 5, 3.5
I know this is something awk/sed would be great for, i just dont have enough experience with them to accomplish it, Also, what about averaging those columns together? so, after I output this to a file, id like to get another like:
1, 4.58 1, 4.125
The number of colums to add might not always be 4 either. EDIT: this might be easier to do in gnuplot, so I mainly just need an answer to the first part.
I'm not that familiar with sed and awk in order to be able to solve this problem on my own, so I'm calling on you for a bit of assistance. I'm writing a Nagios plugin to check our Oracle tablespaces and the output is given in one line like this: 1.04007771 TEMP 0 UNDOTBS1 .005340579 USERS 0 7 rows selected. I've been playing around with sed like below to delete the obsolete info and change every second space into a newline:
[code]...
how many tablespaces there are so I'd have to check all databases and 'hardcode' the tablespaces in my script. Is there any way to 'automate' this knowing that 'rows selected' preceded by a number is always the last line and using a sort of counter to auto-adjust the number to put in the -e 's/ / /2' part?
