how i can add Add text at the beginning of each line?

for example:- i have file contain:-

/var/lib/svn/repos/b1me/products/payone/generic/code/core
/var/lib/svn/repos/b1me/products/payone/generic/

i want it to become:-

svn+ssh://svn.xxx.com.jo/var/lib/svn/repos/b1me/products/payone/generic/code/core
svn+ssh://svn.xxx.com.jo/var/lib/svn/repos/b1me/products/payone/generic/code/fees

One way to do this is to use awk.

awk '{ printf "svn+ssh://svn.xxx.com.jo"; print }' <filename>
If you want to modify the file in place, you can use sed with the -i switch.

sed -i -e 's_.*svn+ssh://svn.xxx.com.jo&' <filename>
