Pretty new at shell scripting. My server was hacked and instances of links for viagra were placed in it. I have lots of sites, so I need to search for all instances of "viagra" and list the files, so I can go remove the intrusions. Can this be done using shell?

Thanks.

I'm going out on a limb and assuming you are using linux. If that is the case you can use grep to find the word:

sk@svn:/tmp$ ls
sk@svn:/tmp$ mkdir -p ./some/junk/dir
sk@svn:/tmp$ echo "viagra" >> ./some/junk/dir/somefile.txt
sk@svn:/tmp$ grep -l -r -i viagra .
./some/junk/dir/somefile.txt

For grep --
-l: list files, not the lines
-r: recursive
-i: case insensitive

Are you using wordpress it happened with me few days back ... the reason was the old version of wordpress

Yes, it can. A simplistic way to find all affected files, leaving you to do the rest of the work:

find / -type f -exec grep -li viagra {} \;

Or, assuming you are on a reasonably POSIX-ish system, a more complex way to find and edit all affected files, minimizing the effort you must exert:

find / -type f -exec grep -li viagra {} \; | while read a; do
  echo -n "Press <ENTER> to edit "
  tput smso
  echo -n "$a"
  tput rmso
  echo "  or <CTRL/C> to quit"
  read b </dev/tty
  vi "$a" </dev/tty
done

The tput() commands assist clarity, but aren't vital; delete them if your system doesn't speak terminfo. This is re-entrant. You don't have to remember where you were when you took a break or erred; once the noxious content has been removed, find() won't find it again.

This works on Debian Linux.
