Normal commit is composed by files and message. The last one is defined thanks to -m flag. To send more than one paragraphs in commit message, we can use several -m flags in commit operation:
git commit NewFile.java OtherFile.java -m "main commit message" -m "this commit add new Java files but doesn't update database because it must be made by administrators"
Previous command will commit two files with a message "main commit message". This message will appear in the first paragraph. The other message, more verbose, will be concatenated with the first one and displayed in new parapgraph. Sample output could look like (git show commitSha):
commit commitSha Author: Bartosz <> Date: Wed Aug 1 06:17:12 2015 +0200 main commit message this commit add new Java files but doesn't update database because it must be made by administrators
