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.
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 ?
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 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
But the variable $sentence can not be identified in ' ' . And also you can see I just want to update the old file. But the sed command can not save the file for me ,so I need to write them to a new file and over write the new file .
I am beginner in this business of shell script and I have no idea how to do the following: I would like to replace the lines of my file that contains 'CFL=' by 'CFL=0.5'. Note that I want to replace the full line meaning
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'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
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 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 want to search a file for a particular pattern and if pattern found replace the line with new text. i am using awk 'match($0,"pattern") != 0 {print $0} ' filename to check if the pattern exists.how do i get the line number of the pattern and delete that line and replace the line with my new text?
I have a Dell precision M50 which has the NVIDIA Quadro4 500 GoGL. When I upgraded from 10.04 to 10.10 the proprietary NVIDIA driver stopped working. At that time I found a simple solution which was to replace in the xorg.conf file the line in the Section "Device":
I am trying to write a script that takes an input file ($FileName) and an intermediate file ($FileName.info) and removes lines from $FileName if the value in $2 of $FileName.info is <75.
I can't figure out how to feed only one line of the .info file to the if statement at a time so that it will perceive it as an integer instead of a list.
The error I am getting now is ./script.sh: line 6: [: : integer expression expected
I've written a script to parse a file and print each line that ends with matching pattern, if the next line is blank. The pattern lines are the result of md5sum $i|sed 's/path///g' so that only md5 and filename appear. Here's what I'm using.
Quote: for fline in `sed -n '/.*.ext$/p' file1` do if [ "`sed -n -e '/'"$fline"'/ {n; p;}' file1`" == "" ] then echo ""$fline" has no info" >>file2 fi done [Code]....
I am combining data from a couple different input files and creating an output file in a specific format. I notice that if I use the >> operator, information gets appended to a new line in my output file. This is useful, but if I'd like to append onto the CURRENT line, is there an easy way to do this? I've been googling around and see lots of complicated answers, nothing that suggests to me an easy way to do this. For example, if my output file looks like this:
b1a:] cat test hello my name is b1a:]
and I'd simply like to append "Bob", how can I do it? If I use
b1a:] echo Bob >> test b1a:] cat test b1a:] hello my name is Bob b1a:]
So what I would prefer is some command that would create the result:
I have txt file with list of ID's and I need to insert comma in every line and then remove new line character so it'll become one long string. So to clarify, I have txt file content that looks like this.
234 5466 2356 ... and so on.
but I would like this to change to 234,5466,2356,... I looked at sed and tried to wrap my head around the commands but I guess my brain isn't smart enough. its really confusing for me. I've managed to add commas to end of line (sed "s/$/,/g" filename) but somehow I can't seem to remove new line character from each line.

I am having difficulty getting sed to replace a string of text in an XML file, despite the fact that I have no trouble using grep to find that same string. Since the new string and old string to be replaced contain a lot of special characters, I thought it best to store them in variables as opposed to using a slew of backslashes:
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.
