I'm trying to work up a sed command for the command below. I'm trying search for v=window.location.search.match in a file and replace it with <script src="//ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>

Here is what I have so far:

sed -i.bak 's/v=window.location.search.match/\<script src="//ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"\>\</script\>/d' myfile.txt

After running this I get the following error:

sed: -e expression #1, char 49: unknown option to `s'

I'm confused as to where I should be placing each \ for escaping.

    use this format: s_A_B_ ; this command replace all A with B – بارپابابا Nov 9 '16 at 20:37
  • Thank you, Babyy that seemed to have done it. I'm now just wondering what I do to replace the entire line that contained v=window.location.search.match instead of just that matches. – hashwagon Nov 9 '16 at 21:16

As pointed out by @Babyy, if your expression contains / characters, then you can change sed separator to something that won't risk to be found in your input file, such as | or _

sed -i.bak 's|v=window.location.search.match|<script src="//ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>|' myfile.txt

Now if you want to replace the entire line, the first part of your expression should match everything, from line start to its end:

sed -i.bak 's|^.*v=window.location.search.match.*$|<script src="//ajax.googleapis.com/ajax/libs/jquery/1.4.3/jquery.min.js"></script>|' myfile.txt
