General :: Search And Replace Line In Multiple Files?
Jul 13, 2010
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.
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'm fairly comfortable with emacs but I can't seem to find how to do this. I deal with a lot of text files and find myself performing a lot of regular expression replacements to correct the formatting of the text -- or to extract certain tidbits of data from large ugly-looking files.
I know how to perform a regular expression replacement in one buffer at a time. But how do you perform a regular expression search and replace across all open buffers? I have found a method to perform a regex search and replace across a directory by marking files but I need to do it in the open buffers.
But the problem is that in this case i just wanted to append "/home/dest" for which I could easily escape "/" with just two "", but I wonder if i have a long path like "/a/b/c/d/e/f/g/h/i/j" I will have to escape so many /. Is there any other way by which I can avoid escaping forward slash.
I tried following:
But receiving follo error
Bareword found where operator expected at -e line 1, near "s/destination-path=/'destination-path=/home" syntax error at -e line 1, near "s/destination-path=/'destination-path=/home" Bad name after dest' at -e line 1. tried with enclosing in double quotes as well but in vain
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 need a command to search a string in a file and then to convert the next string in the same line from hexadecimal to binary. I was able to put everything in capitals. The original file can be as such:
E 2 C 1 794 T ffff E 2 C 1 787
It is not always FFFF! I am trying to do this in a file at once, not reading line by line (using while).
I want to do search and replace in multiple files. I've seen that it possible to create a sed script but I haven't got the talent to do it myselfWhatd is to locate all instances of a word - lets say 'day' - and replace it with for example 'night' in all odm-documents in a specific folder. It would be great if the search only matched whole words and was case sensitive.
After hours (literally) of searching the web and reading man pages, I think I've come up with the following:Code:find . -exec grep 'path/to/file' -print | xargs -0 -I new_path mv {this is where I get confused}So my code above is incomplete, obviously. In order to finish replacing the string, I need to mv the new file into the old file's spot. How do I do this, by incorporating it into my line of code?
Long story short, I got a folder with nearly 800,000 php files. I would like to search each file for a string and if it exists in that file, the file gets copied to another directory. Is this possible from the terminal? So far I got: grep -i -n -r 'ppr-1792' * | cp $1 move_to_here
But this obviously doesn't work. $1 needs to be the file name that contains matching text.
I often use the rpl command to make changes to multiple html files at once. For example:
rpl -R '<br />' '<br /><br />' mydirectory However, I haven't been able to figure out how to change multiple lines. For example, let's say I want to change all occurrences of :
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 need to replace ":" from multiple files names, since I am going to copy those files from a linux partition, which admit the ":" to a FAT32 partition, which does not.
Example: original name: eg06_ana_21-05-06_09:21:03.JPG wished name: eg06_ana_21-05-06_09-21-03.JPG
I have googled a lot but I have not been able to adapt the examples given by people to my aim.
It seems that rename command is what I should use, but I have no idea to build the correct pearl expression.
I am trying to replace a string (url) in 100s of files located in different directories. I found the sed command but cannoy get it to work. First I locate the files that have the string in them:
Code: grep -ilr 'url' * this works correctly and displayed the location of the files that have the string: Code: 1/index.php 2/index.php
Now I need to replace the string so I combined it with sed:
I want to change some HTML in my files (80+ so I prefer not to do this by hand). I got a script to replace a string in files, however the HTML I want to replace contains an enter (and tab of 4 spaces) (explanation below) Does someone know how I could update my HTML by using a function in Linux?
I also found sed but don't know how to use it with the enter (linenumbers will not work because they variate)...
I am trying to search for a term in a bunch of files. Is there a way to do this. I would like to search all the files in a directory and its subdirectories for a specific term.
How to search multiple words in multiple lines, inside a directory including sub-directory? Pls. give easy example. I want to search the files (in /xx folder and all subfolders) that have header.h included and used x() function. I tried $grep -r "header.h" | grep -r "x(" /Folder/subfolder/ > search.log
In the above code ^<YAHOO> search is not working (I want lines "except YAHOO"). I know that [^ab] will work for "except a,b" characters. How can I say "except word" in regular expressions?
I have a file that is in almost all my /home web accounts, here: /home/accountXXXX/public_html/cms3.0.php in that file is a line I want to get rid of: <script id="jslocal" language="JavaScript" type="text/javascript" src="/site-local/local.js"></script>
is there a simple shell script that would recurse all /home/xxx/public_html directories, and then yank this line (it will always be exactly the same) and better yet, for future, is there any way I can REPACE that line with another..
I've got a list of files that I've copied from my terminal and pasted into gedit and into OO.o writer. Since the files are all created by gedit, in each case there is both file and file~. I want to get rid of all the 'file~' lines. I thought I could do search and replace using *~, but this doesn't work.
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.
