One of my websites has been hacked, all the index.html and index.php files have been infected with a certain Javascript. I would like to have a unix command to remove this script from all files.
Script is here: http://pastie.org/private/6osrvd5zhphe372gblrc6w
I am trying to figure this out with sed but no luck so far
Thanks!
sed -i 's/<script>.*<\/script>//' fileName
will remove the tag script and all its content.
This works if you only have one <script> tag.
If you haven't only one, extend it with try keyword in the following way
sed -i 's/<script>try.*<\/script>//' fileName
Edit
If you want to do it on all files in a recursive way, you can use a find command like this:
find . -name "index.html" -print | xargs sed -i 's/<script>try.*<\/script>//' fileName
where . is the current directory
You can try this
find src/ -name "index.html" -print | xargs sed -i 's/<script>try{document.body++}catch(dgsgsdg){zxc=12;ww=window;}if(zxc).*<\/script>//
perl -pi -e 's/<script>.*<\/script>//g' index.html

How do I prepends a special character in front of all the lines in all .txt files in my directory? Im new to writing bash scripts and having trouble doing this. I only know of using the grep function but thats only to search for keyword.
For now, I have this,
sed -i 's/^/#/' Machine1.txt
However, this is only for that specific .txt file. I want to do this for all files with a .txt extension in my directory. There are other extensions like .tar, .rpm, .sh files which I want to ignore. Thank you!
Just give a wildcard filename argument.
sed -i 's/^/#/' *.txt
you can use for loop.
For example
cd your_folder
for f in *.txt; do
sed -i 's/^/#/' "$f";
done
I can do the find and replace a string in multiple files with the below command.
find . -name '*.py' | xargs sed -i 's/foo/faa/g'
Can we do the same by using Perl?
Try this command...:
find . -name '*.py' | xargs perl -p -i -e 's/foo/faa/g'
N.B.: If you want to make a backup copy of your files before changing them, provide -i flag with an extension... I.E.: -i.bak...
I need to strip down all console statements (console.log, console.error, etc) from all javascript files in a folder. How do I do that?
trying this:
perl -pi -e "s/console.(.*);/g" *.js
doesn't work properly. I have to delete everything that starts with console. and end with closing parenthesis, not semicolon
Supposing that all your console commands are in separate lines you can try something like this
perl -pi -e "s/^\s*console\.\(.*?\);\s*$//g" *.js
Not tried but what about a short sed?
For example:
find . -name "*.js" -exec sed -i "s/console\.[^\)]+\);//g" '{}' \;
I'm trying to change the name of "my-silly-home-page-name.html" to "index.html" in all documents within a given master directory and subdirs.
I saw this: Shell script - search and replace text in multiple files using a list of strings.
And this: How to change all occurrences of a word in all files in a directory
I have tried this:
grep -r "my-silly-home-page-name.html" .
This finds the lines on which the text exists, but now I would like to substitute 'my-silly-home-page-name' for 'index'.
How would I do this with sed or perl?
Or do I even need sed/perl?
Something like:
grep -r "my-silly-home-page-name.html" . | sed 's/$1/'index'/g'
?
Also; I am trying this with perl, and I try the following:
perl -i -p -e 's/my-silly-home-page-name\.html/index\.html/g' *
This works, but I get an error when perl encounters directories, saying "Can't do inplace edit: SOMEDIR-NAME is not a regular file, <> line N"
Thanks,
jml
find . -type f -exec \
perl -i -pe's/my-silly-home-page-name(?=\.html)/index/g' {} +
Or if your find doesn't support -exec +,
find . -type f -print0 | xargs -0 \
perl -i -pe's/my-silly-home-page-name(?=\.html)/index/g'
Both pass to Perl as arguments as many names at a time as possible. Both work with any file name, including those that contains newlines.
If you are on Windows and you are using a Windows build of Perl (as opposed to a cygwin build), -i won't work unless you also do a backup of the original. Change -i to -i.bak. You can then go and delete the backups using
find . -type f -name '*.bak' -delete
This should do the job:
find . -type f -print0 | xargs -0 sed -e 's/my-silly-home-page-name\.html/index\.html/g' -i
Basically it gathers recursively all the files from the given directory (. in the example) with find and runs sed with the same substitution command as in the perl command in the question through xargs.
Regarding the question about sed vs. perl, I'd say that you should use the one you're more comfortable with since I don't expect huge differences (the substitution command is the same one after all).
There are probably better ways to do this but you can use:
find . -name oldname.html |perl -e 'map { s/[\r\n]//g; $old = $_; s/oldname.txt$/newname.html/; rename $old,$_ } <>';
Fyi, grep searches for a pattern; find searches for files.
I'm looking for a sed command that, with find, I can take a directory tree of JSP files and write the name of the file in an HTML comment to the top of the file.
This will allow me to review a legacy application JSP call tree of in the HTML source.
I'm thinking it will be a one liner for a talented sed guru...
something like:
find . -name '.jsp' -exec sed ? ? ? {} \;
Maybe something using xargs is more appropriate, but I think sed is the tool that will do the work.
If you want to use sed, you can try
find -name "*.jsp" -exec sed -i '1i <!-- {} -->' {} \;
Works fine for me in the presence of /.
On Unix the filename will contain slashes (/) which are special characters for sed, so I would recommend this simpler approach that writes the filename at the bottom of the file:
find . -name '*.jsp' -exec sh -c "echo '<\!-- {} -->' >> '{}'" \;
To write the filename at the top of the file use this:
find . -name '*.jsp' -exec sh -c \
'echo "<!-- {} -->" > "{}.new" && cat "{}" >> "{}.new" && mv "{}.new" "{}"' \;
N.B. The filename might contain characters that might render your HTML invalid, e.g. &, although I doubt that a JSP could have such a strange name.
