Question Search and replace links


Hello all,
I am trying to figure out a way to search and replace text links within pages in all web folders on our server at once.

Ex: replace all instances of www.wherever.com
with : www.here.com

Any ideas? I am not local to the machine, so all work is done through remote ssh1 connect in shell.
I tride using this:

perl -pi -e "s/www\.oldsite\.com/www\.newsite\.com/g;" *.html

But, perl doesn't seem to like going recursively into directories.
Any help would be appreciated. Thanks,

Xtrude

Try with sed:

sed 's/www.wherever.com/www.here.com/g' *.html

Hope that helps ...

vlad, would that work on subdirectories as well? And, would it work for things like email adresses (in the html form <a href="mailto"whatever@whatever.com">Webmaster</a> and changing just the "whatever@whatever.com" to "Whomever@whatever.com")?



Thanks

I forgot something, using sed will show the result as stdout, so it's necessary to direct it to a file:

sed 's/expression/other expression/g' file > other file

So It should be easier with a shell ( could be used with email addresses too, and subdirectories ) :

# for file in `find . -iname *.html`; sed 's/whatever@whatever.com/whontever@whatever.com/g' $file > $file.new ; done

I did something like this once, when our webserver (at the university was reconfigured):
It's a bit more complicated than the above versions since i use vim
to do the editing.

basically the server was moved so it was accessed
through student.cosy.sbg.ac.at
instead of ww.cosy.sbg.ac.at
the following did the trick, the www2stud file is attacked.
Grep only reduces the number of replacements done, but it can be
removed without making much of a difference.

#!/bin/bash
script=/home/stud1/user/bin/www2stud
repl=0

for item in `find -name '*.html'`
do
echo -n "scanning ${item} ... "
repl=`egrep -c 'http://www.cosy.sbg.ac.at/~user' ${item}`
if [ $repl -ge 1 ]
then
echo "replacing"
`vim -e -s ${item} < ${script}`
else
echo "clean"
fi
done

www2stud:
------------
:%s/\(http:\/\/\)www\(\.cosy\.sbg\.ac\.at\/\~user\)/\1student\2/
:x
-----------
