(if need be, i think i can just add another line of "-e /s/char/newchar/" if i need to target more charecters or words as needed.) the issue with the above code. . . how do i get it to target whatever text file follows the command? without having to manually designate sed to it each time? e.g. in commanding:
When I grep kernel.exec-shield I get both line, hence I keep over writing the kernel.exec-shield-randomize in my script because it finds them both for my sed commend.
How can I get an exact match with either sed/awk/grep in shell so I can do a find and replace?
Example: sed 's/^kernel.exec-shield =.*/kernel.exec-shield = 1/g' /etc/sysctl.conf will replace BOTH lines
Example: grep "^kernel.exec-shield" find both line and I want it to find only the exact line.
This is what I have right now. Well, I thought I knew sed, and apparently I don't... I tried writing this for someone else, and this has given me trouble, so since the user pretty much figured it out on his own, here it goes. Say VARR=1, so VARX and VARY contain the above text, appended by 1. What I am trying to do is replace the text "defaults.ctl.card 0" by VARX and "defaults.pcm.card 0" by VARY. The contents of FILE1 is the file being used to search for both text fields, and FILE2 is the output file. I tried using single quotes, double quotes, and a mixture of both, and no go whatsoever. So my question... What is the proper way of searching for text within a file and replacing with a variable?
Is there any way to use sed to replace certain text in a file with the persons username automatically? Right now i'm using Code: Select allsed -i.bak s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g file.foo
I would like it to automatically inject the persons usrname in the replacement string. Is this possible? I've been looking on line at various sed tutorials and I cant quite find what i'm looking for. I also didn't really see anything in the forums search function.Essentially i'm trying to take this file URL...Android.rules and replace all instances of username with the persons actual username automatically.
As indicated in the subject, I want to search a text. If the text is present I want to replace it. But if the text is not present, I want to insert it after first line and before last line.
I want to use SED to do the following: In a text file replace any occurrences of the three character string ZZZ with a quotation mark "and. replace all occurrences of a comma with a semi-colon. It is the S/ / / command which is stumping me on the first issue...inparticular how to get the replace string to be quote.
Something very handy to do in a Linux shell, is manipulating files and strings - essentially parsing data. Write a utility which will scan in a text file and search and replace strings. We also want to keep track of how many strings we've replaced.
I know that my command would look like this: <utility name> <filename> <stringToSearchFor> <stringToReplaceWith> Code: #!/bin/bash
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?
The problem I have is that I need to replace a more complex string, like this: Old string: /mnt/stor6-wc2-dfw1/627896/982574/ New string: /mnt/stor8-wc2-dfw1/369587/302589/ There I don't know how to do it... since the / is what separates the old from the new strings, and the strings that I want to replace have / in it. Also, I would like to know how to specify under what folder replace the files, for example, I want that it search/replaces all files under /var/www/mysite/htdocs folder.
I am trying to write a Perl script that can open a file, find text that appears between two identifying strings (for now, "start" and "end"), then modify that text by enclosing it between "term_" and "_term" . Since the identified strings vary, the replacement string becomes "term_$1_term". From looking at other threads in this forum I've been able to get as far as spitting out the modified terms using the following code:
open FILE, "start2.txt" || die ("Could not open file <br> $!"); $text = <FILE>; while ($text=~ s/start (.*?) end//) {
[code]....
The problem is how to get "term_$1_term" into the file in the same while loop, which I'm guessing would be some of variant of "$text=~ s/$1/$term/;" (which doesn't work as it stands).
I have a many directories each with about 20 html files inside. All the files have .html ext. What I'm hoping is possible is from command line to find some text in each one and replace it with some other text.
Basically what I want to replace is;
/awstats/ with awstats/
I can do this easily with dreamweaver or some other application but because I have 960 pages total to do I'm hoping to do it this way.
I have an SQL dump, file.sql that has many references to a particular domain, d1.com. I would like to run a command that can replace every occurrence of d1.com with d2.com. I've tried looking into sed before but the man pages are quite daunting.
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'm having problems with Tomboy. I have a few hundred note files and I need to go through all of them and replace all instances of "<link:broken>a</link:broken>" with "a". Is there a bash command I can use to do this?
I need some help in determining how to have a color splash image display in place of the Linux scrolling-text during the boot-up process on an embedded Linux device. The kernel used is a stripped-down version of Linux (kernel 2.6.29), which has been custom configured. I am using syslinux as the bootloader. I was told that Plymouth might be the way to go with this, but I'm not sure.
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
What I have works, but wondering what is the 'right' way to replace the digits with the letters given in this loop? somehow use a case or multiple sed? i thought of a multiple sed or a case but couldn't get it to work
Code:
# ... bcv=$(echo $line | awk -F" " '{ print $1 }' | sed 's/1/q/g;s/2/w/g;s/3/e/g') # and so on
Code:
while read line do bcv=$(echo $line | awk -F" " '{ print $1 }') if [ $bcv == "" ]
What i want to do is pretty simple.I want to uncomment every line that begins with "deb" (except for deb cdrom) in /etc/apt/sources.list.I know how to do this through system > administration > software sources.I know I can gksu gedit /etc/apt/sources.list.I'd rather not do it that way.I'd rather have a script do it. It's less work, less typing, less clicking, and would work the same on every ubuntu version.
I'm pretty sure this is doable from the command line, but my CLI skills have degraded a lot since my pre-Y2K admin days. The goal is to search all the files in the directory for a very long string of text and replace it with another string of text. The text being searched for is my Google Adsense code (which will be stripped from my website) and it will be replaced with a placeholder so I can easily tack something else in there in the future.
Seeing how I have that long snip of code on about 100 pages, automating the process would make life easier. If I was searching for a single word, I can see ways to do this. If I paste the code I'm searching for into a text file, is there a way to: find (contents of oldstring.txt) and replace with (contents of newstring.txt)?
i am on processing text tasks And i found that if you assign a text to a variable is chomp'ed automatically the newline
Code:
variable=$(cat file.txt)
The problem is i can only access the items/lines using:
Code:
for line in $variable do echo $line # Other commands done
how do i convert this to an indexed array. More importantly, how do i get access to individual $line[0], ..., $line[n] Another thing, if the file.txt, has lines with spaces it is a mess using the for...in..., but echoing prints line by line...o_0
I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.
I have to delete a certain line of text from the a textfile via ubuntu's shell scripting.I have done research, and it seems that most people advocate the usage of sed /d option. sed makes does not edit the text file. Hence, most options I discovered involved the use of a temporary variable/textfile and then overwriting the old file with the temporary new file. Is there anyway whereby I can bypass the use of temporary storage containers? I hope there is any magical combination of commands to edit the file directly.
I want to display something in my text view widget in glade using c code. that's all right. now I need to attach a save button beneath the text view.so that on click the text view content should save as a txt file..
I want to display the contents of a particular log file (simple text file, I mean in Linux). But there is a problem: The contents need to be organized in a fixed format. Have a look at this log file:
So, while displaying the contents of above file on a web page, I want to format the field names found in the log file: User Name:, Reported Problems Description:, and Remarks:. These fields may contain a variable length of text and no specific line number is assumed for them to appear on.
Well, what I am trying to do may sound wierd to some of you. The filed "Reported Problems Description:" can possible contain text which embeds colon (.
I am trying to find sed command combination to print out the "start command" line, the id line and all lines between "details" and "stop command" only if "error" exists. Here's the original output (test.txt):
a sed command to add a text before line number in text file? I have text file with 500 lines, and i want to add 3 more lines with text after line 300, OR before line 302, isn't no problem.
