Shell Programming and Scripting

Hi

I have around 1000+ java file under different folder in /home/raxit/source and in each file i want to add a fix method.

--------
/*
Some comment for few lines
like header block etc..
*/

package

import

class A {

method1 ()
{
}
method2 ()
{
}
..
..
method n()
{
}

/*----
i want to add method n1() here before class ends...
*/
}

Few blank lines/tabs/space/comment
--------End of file ----

Any perl/sed handy script to do this task ?

Raxit

Assuming you want to add the method in class A and you have the new method in a file called method_n1:

Code:

awk '
/class A/ {f=1;c=1;next}
/\{/{c++}
/\}/ && f && !--c{system("cat method_n1");f=0}
1' file

u mean to say u have 1000 files and all 1000 files have same structure.
and before the class ends u want to put 1 method in it.

is this what u exactly want. can u also clarify if its the same class in all the files and same method has to be added.

Yeah, I want to add same method to each java file. Not all files are equal, but i want to add some tracking method, that i further use with.

More simplified way.... and more clearly something below...

1. In /home/raxit/SRC directory and sub-directories multiple source file including java source file which i want to edit.

2. script will go to each directory + sub-directory subsequently and open each java file

3. search for last closing curly bracket } . This may not be at last line ! because file may have white spaces after last closing }

4. replace it with public final string string1="MyString"; }
