[tutorial]Add build.prop lines from cwm - Sony Ericsson Xperia Neo, Pro

I have seen many questions about build.prop editing but very less of them have been convincing to be solved and modders don't need to tell people to add lines from next time​
First how to make a script sh file which contains your prop lines

Click to collapse
Open npp and type:
#!/sbin/sh[This is the first line to call busybox]
busybox echo "" >> /system/build.prop[Call busybox for prop file]
busybox echo "Title of your added lines" >> /system/build.prop(not recommended but works absolutely)[This is the description line which is written inside build.prop for understanding of your apk's value nature..]
busybox echo "ro.config.ringtone=opal.ogg" >> /system/build.prop....(And just the same way add lines)[This line put your default ringtone to opal.ogg]
Provide a line break
busybox echo "" >> /system/build.prop[Call this line again for busybox to finish prop file]
save file with script.sh extension.....save it at the main folder which contains meta-inf folder too...
Add these lines to updater-script after
Click to expand...
Click to collapse
ui_print("Adding lines to build.prop");
package_extract_file("script.sh", "/tmp/script.sh");
set_perm(0, 0, 0777, "/tmp/script.sh");
run_program("/tmp/script.sh");

For modifying the script ...like deleting prop lines....its quite hard to manage through it..end up in bootloops...will see to work it out...if any of you have got the deleting prop lines successful then post here

Try this one
Code:
{ sed -i "/^$1=/{ h; s/^$1=\(.*\)/# $1 was \"\1\"\n$1=$2/ }; \${ x; s/$1//; x; t e; s/$/\n$1=$2/; : e }" "$TMP"; }
this will search your build.prop for a line and replace it with something that you want it to be... then it will echo all of that to a temporary file of your choosing for reference. it will also comment out what the old prop was

Friend, npp means notepad ++ ..you can get it from sourceforge.net ...and for later instructions type and understand meaning written in brackets
And yes...you need to read more threads around xda so you can understand more threads easily..
Enjoy reading

Can you explain this a bit further in terms of usage? What part of this code is the line to be replaced and the line to be supplanted? I assume 1 & 2 are the lines, but I still don't quite understand... Maybe you could give an example? Thank you.

Hello, learn more about sed here...my friend once implemented it on galaxy s2 for verification....but same script did not applied for xperia series...so i think its more important to get to know deep about its usage......
SED-Complete Document(Unofficial)
Always share knowledge, sometimes we might get more than we know
