That's not too difficult. Use 'cat my-file | sed -e "s/msnr/usr2" >my-file' to change the files in place or 'sed -e "s/msnr/usr2/" <in-file >out-file" to retain the original files.

Sure the sed command I used above silmply replaces 'mnsr' with 'user2. If you want to replace it with 'msnr:usr2' use 'sed -e "s/mnsr/mnsr:usr2/ <in-file >out-file'.
