Commit in Git

Jerry commits (deposits) the changes and he wants to correct them for his recent commits. In this case, the function git commit -a will help do this. This function changes the last commit including your commit message; It creates a new commit ID.

Before custom operation, he checks the commit log.

 [jerry @ CentOS project] $ git log 

The above command will produce the following result:

 commit cbe1249b140dad24b2c35b15cc7e26a6f02d2277 
 Author: Jerry Mouse 
 Date: Wed Sep 11 08:05:26 2013 +0530

 Initial commit 

Jerry commits new changes to the --a function, and observes the commit log.

 [jerry @ CentOS project] $ git status -s 
 M string.c 
 ?? string 

 [jerry @ CentOS project] $ git add string.c 

 [jerry @ CentOS project] $ git status -s 
 M string.c 
 ?? string 

 [jerry @ CentOS project] $ git commit --a -m 'Changed return type of my_strlen to size_t' 
 [master d1e19d3] Changed return type of my_strlen to size_t 
 1 files changed, 24 insertions (+), 0 deletions (-) 
 create mode 100644 string.c 

Now git log will show a new commit message with the new commit ID:

 [jerry @ CentOS project] $ git log 

The above command will produce the following result:

 commit d1e19d316224cddc437e3ed34ec3c931ad803958
