Ubuntu :: Command Line - Find And Replace Text Within Multiple Files?
Aug 28, 2010
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 found this command that works great finding and replacing a simple string to another in files located in that folder and all sub-folders.
Code: find . -name '*.php' | xargs perl -pi -e 's/OldText/NewText/g'
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.

Is there a way to specify to find that I only want text files (and not binary files)? Grep has an option to exclude binary files, so I thought find probably has a similar feature, but I've been unable to find it.

command line, I have a server for work that I ssh into and I need to be able to find multiple files (they have the leading text just the date identifier changes) and then zip the files (with bzip) them and then finally scp(Secure copy) them to another server.
These files are always in the same directory and this is a daily task and just want to make into a script that I run once I am logged into the remote server.

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 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.

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?

I liked the idea of the "cosmos" screensaver/desktop, but wanted to add my own pictures to the application. I navigated to /usr/share/backgrounds/cosmos and tried to drag and drop. I quickly found that I did not have permission to do this.
I googled my problem and found some command line tutorials telling me to sudo cp. My problem is that I have about 30 pics that I want to move in there, and I don't think I can just move the directory, they have to be in that folder as the pictures themselves.
I don't really feel like typing the cp line multiple times with multiple randomly named image files.
Is there a way to have the command line cp all of my files from one directory to another?

I have huge text files with two fields, the first is a string the second is an integer. The files are sorted by the first field. What I'd like to get in the output is one line per unique string and the sum of the numbers for the identical strings. Some strings appear only once while other appear multiple times. Given the sample data below, for the string glehnia I'd like to get 10+22=32 in the result. how to do this either with gnuwin32 command line tools or in linux shell?

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 :
<br />
<br />
to:
<br />

rpl -R '<br />
<br />' '<br />' mydirectory
but that didn't work. how to do this with rpl or some other way?

I have 2 text files : file1.txt and file2.txt
cat file1.txt
15 this is a sentence containing various words and spaces
34 this is a another sentence containing various words and spaces
cat file2.txt
2 this is sentence1file2
6 this is sentence2file2
54 this is sentence3file2
I would like to join these 2 files. The result should look as follows :
cat joinedfile.txt
2 this is sentence1file2
6 this is sentence2file2
15 this is a sentence containing various words and spaces
34 this is a another sentence containing various words and spaces
54 this is sentence3file2
==> so the joined file must be sorted on the first number. Any ideas how this can be achieved ?

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 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:
sed -r 's/(^[a-z'-]+ [a-z'-]+) /1|/' filename.txt

I have a sysctl.conf that has the following in it:
kernel.exec-shield-randomize = 1
kernel.exec-shield = 1
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.

I have a file with the following in it:
:0 local /usr/X11R6/bin/X -nobanner
:1 local /usr/X11R6/bin/X
I need to add "-nolisten tcp" to both of these lines and cannot figure out how to do it. I can get it to do the first one, but not the 2nd and so on. How do I search the file and loop though it to change them all?

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 == "" ]

I would like to have a script that will do a search in an XML file for a specific block of XML code and replace it with a different block of XML code using the Windows build of GNU Sed 4.1.5.
Here's the text I want to find:
Code:
And here's what I want to replace it with:
Code:
There is however a lot of stuff in there that would mess up sed, and the one example from the sed FAQ (from the Sourceforge site) that looked promising and easy enough to figure out (4.23.3. Try to use a block of "literal strings") fails with this error message: sed: file blockrep.sed line 18: unterminated `s' command
Anyone got any ideas, or even an alternate program that can do this? (Preferably one that I can automate.)

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 have two txt files containing x and y coordinates: xcoord.txt & ycoord.txt. I need to open them; read them line by line to get each coordinate; then each time I need to update Xs and Ys parameters inside another file called "dc.in" with the grabbed values.
Finally each time I need to run two exe files ( dc_2002 and st_vac) and produce corresponding output for each Xs and Ys ( dc.in is an input file for this exe files)
I have written the following code but it does not work:

For example, I always go to this path:
/user/something/somefolders/somewhere
but I don't want to type
cd
/user/something/somefolders/somewhere
in the terminal all the time, can I have some short hand to do so? for example, can I do something like
cd commandPlace
to replace the path?

Here's the actual line of code, which exists in a bash script:
Code:
I want to replace instances like this:
Code:
with this:
Code:
Using this:
Code:
Which works great when there's only ONE of the pattern on the line. But in a case like the "actual line" I posted first, where there are two patterns, separated by a slash, only ONE gets replaced
Watch:
Code:
Why? There must be (among many other things) something I'm not knowing about sed, that's causing this.
-- I'm currently using the ~ (tilde) as the separator in the sed command. It doesn't matter, I've used / ~ and % with no difference.
-- As a test, I tried putting a different character(s) in the middle of the original pattern instead of the / but that made no difference.
-- I've come up with various similar but slightly different regexs that will do this replacement, but they all have had this same result.
-- I tried the sed single-quoted, double-quoted, and unquoted; the latter fails to execute, and the formers both work as described here: wrong.
