Hi friend,I found the problem in your command.

You remove the slash character after 1.

You try this,

Code:
sed -ri '1s/(.*)/text\1/' inputfile

Even if you have problem with r option,you try the following.

Code:
sed -i '1s/\(.*\)/text\1/' inputfile

Try this,

Code:

See the following example:

it will add the string into the first line of the text file
Code:
sed  -i  '1{s/^/string\n/}' fine_name
