Change a line in a php file thanks to a shell script

Shell Programming and Scripting

Hi,
I'm working on a script to make automatic the new releases of my website...
However in this script I put all the css script in a single one. There's no rpoblem for that.
My problem is when I want to change the header of my layout page to put instead of :

$header.="<link rel=\"stylesheet\" media=\"screen,projection\" href=\"/css/misc.css\" type=\"text/css\" />";
$header.="<link rel=\"stylesheet\" media=\"screen,projection\" href=\"/css/elements.css\" type=\"text/css\" />";
$header.="<link rel=\"stylesheet\" media=\"screen,projection\" href=\"/css/pages.css\" type=\"text/css\" />";

I want that

$header.="<link rel=\"stylesheet\" media=\"screen,projection\" href=\"/css/style.css\" type=\"text/css\" />";

I'm not really good in unix scripting but I've tried stuff like grep etc. without succeeding I'm sure it's not that hard...
Thank you for your future help

Hi

Not sure, whether i understood your requirement right.

sed -n 's/misc/style/p' infile

assuming those 3 lines are present in a file, infile

Yes you got it right but I found it really hard to escape the correct things etc.
It doesn't wanna work do you know a unix function to escape a string?
