I have a file, "outfile" what I wish to insert into a file called template where it finds "OVERRIDES". I am getting an error.
Code:
However I can do something like this and it works fine
Code:
I am guessing its because of the file size or multiple lines.
A sample of the outfile text is below

I have script that I'm working on that updates a username in all the files that are called blah.inc for my framework. since i host a bunch of these web apps i need to do it to all of them. so I need to figure out how to update these files automagically with out me watching it to call vim every time. heres what I have so far

This finds the files but now i need to figure out how to do s/bob/fred/g on those files.
I've found some scripts that replaces a string in a file but it's not quite working for me.
And I'm trying to replace a tag in an xml file that looks like this
So I ran a command line like this perl -w -i -p -e "s/xmlns="'http://mydomain.org/replacethese.xsd'">/>/g" testfile.xml
And I get a error output
Search pattern not terminated at -e line 1.
Found the script from this blog [url]
There are a few things I was wondering about (using tools available in bash):How to insert a file at at the specified location of another.How to copy a portion of a file between two lines matching a regex to another file (and/or making sed only work between two lines matching a regex)How would you do this?
View 2 Replies View Relatedi need to change a binary file, let's say to find and replace username:
find string: "/home/name/bla-bla-bla/ "
new string: "/home/anewname/bla-bla-bla/ "
i can do it, for example, in emacs (hexl-mode), but interesting in writing a script instead. it will be much more better for me if i could do it automatically. is there an analog of: sed 's/string1/string2/g' ? P.S. the best way is to recompile the binary files i have, but there are no sources available.
I know how to replace a particular instance (say 3rd one) of a word in a line using sed based on the sed one-liners. However I would like to replace a particular instance of a word in the entire file.
For example, here is a file:
Code:
John
Betty
Jack
Ron
Jack
Paul
So now I would like to replace the second instance of Jack (in red color) with "Rob" (for example). Not quite sure how to do that? I tried couple of things from here but they did not work.
I have question about replacing a string in a file.
How can I replace the printerb's 10.1.1.1 to something else(10.1.1.2, for example) without replace printera's 10.1.1.1 accidentally?

I often get files with many spaces as part of their names. I would like to automatically replace these spaces with underscores, but otherwise not change the file name. Is there a way to do this task with just the bash shell?

The variables are clean and available in my script. No prob. $old is an IP-address of a server, $new as well. replacement-file is an xml-file (the ip-address to be changed is within an xml-tag). It should be trivial, but it isn't. I spent the last 3 hours reading about the problem, trying several different 'solutions' or workarounds. It should work, the '"' should take care that the variables get expanded, but whatever I try the old server IP isn't replaced.
I want to read from the file and check for the pattern, if the line has some word like <string>: then string should be copied into buffer. Afterwards, I want to insert the same <string> with some word in the next line of the file. use sed command to perform the above mentioned operations?

View 3 Replies View RelatedCode:

VARR=`cat /proc/asound/cards | grep HDMI | cut -c 1-2`
VARX="defaults.ctl.card $VARR"
VARY="defaults.pcm.card $VARR"
FILE1="alsa"
FILE2="alsa.new"
echo $VARX
echo $VARY
sed "s/defaults.ctl.card*/'$VARX'/g" $FILE1 > $FILE2
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?
I'm wanting to mod some PHP files across a hierarchy and thought I'd drive it with find + grep + xargs
I built up a command line which I was confident would do the job, but now can't save the results.
First I tried this:
Code:
find . -name *.php | xargs grep serialize | cut -d: -f1| sort -u | xargs sed -i s/serialize/serialise/g
but that didn't work:
Code:
sed: illegal option -- i
so I thought I'd try using

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.

I am trying to rename a lot of files but need to keep the extension :
the files are films names :
a.b.c.d.***.iso
the result should be replacing "." by spaces " "
this command :
for files in *.iso ; do mv "$files" `echo "$files" | tr '.' ' '`; done
put a space also before the extension iso ??
How can I rename files from
"a.b.c.d.iso" to "a b c d.iso"
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.
Searched text is:CleanCache "*";
Where * can be anything.
Example: CleanCache "false"; -> CleanCache "true";
If CleanCache "false"; is not present, only insert CleanCache "true"; 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.

View 9 Replies View RelatedSomething 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 wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.
perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";
But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.
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?
View 1 Replies View RelatedI have a js string bounded by single quotes (''). That requires that I escape the single quote (') that occurs in "I'm" or "don't". I want "I'm" to become "I'm". Fair enough. But this doesn't work: sed -e "s/'/'/g" The replacement string is unescapable I believe and must be a literal. How do I do this in sed ?

scriptname textfile
how do i get the script to target textfile^^^?
