Add header(copyright) information to existing source files

Question

I want to add our company's copyright information to all of our EXISTING source code files.

The project is developed in Eclipse. so, for new files I can modify the settings as suggested here. But for existing files, how am I supposed to do this. How can I modify hundreds of java files to add the copyright information. (And I'm unable to open the releng plugin mentioned in the above link.

Any windows based text maniputaion scripting language will also help.

Answer 1

Correcting Konstantin's solution:

find . -name \*.java -exec sh -c "mv '{}' tmp && cp copyright '{}' && cat tmp >> '{}' && rm tmp" \;

Problem was that && is being interpreted by the shell directly instead of being passed to find. Escaping them is no solution either, as the find exec does not understand them. So just give the whole command to some shell.

Answer 2

Please try eclipse Releng plugin.
This would help to fix/add copyright statement in all .java files and .properties.
Simply right click on the project and select "Fix copyright".
Link.

Answer 3

I would install CygWin (core + find) and do something of a kind

find . -name *.java -exec mv '{}' tmp && cp copyright '{}' && cat tmp >> '{}' && rm tmp \;

Answer 4

You can use maven license plugin to do this.

Check this and this. The plugin support templates for your license header, remove the license and check for the license in all your files.
