The shell treats ' and " differently, variables are only expanded inside ", so by using ' you are passing the literal $filename_search to sed instead of the value of the variable.

Found a fix for it although it isn't elegant...

target_filename_search=$(echo $filename_search | sed "s/.xml/.encodation.xml/")
echo $target_filename_search
cp $media_path/$filename_search $media_path/INTRANSFER/$target_filename_search

any thoughts on the first way to do it in sed?

Dear all,

I've got a problem with a SED sequence....could somebody lend me some guidance please.

ls -d $media_path/$filename_search | sed 's/${filename_search}/cp "&" "INTRANSFER\\1.encodation.xml"/' | sh

I want to take a file called channel_dd-mm-yy.xml and copy it into a directory called INTRANSFER with the revised filename channel-dd-mm-yy.encodation.xml

Using simple reg.ex, I can get things to work

echo blahblah.xml | sed 's/.xml/.encodation.xml/'

Thanks

Max
