Jerry creates a copy of the repository on his machine and decides to perform basic operations. So he created the file string.c. After adding content, string.c will look like this:

 #include int my_strlen ( char * s ) { char * p = s ; while (* p ) ++ p ; return ( p - s ); } int main ( void ) { int i ; char * s [] = { "Git tutorials" , "Tutorials Point" }; for ( i = 0 ; i < 2 ; ++ i ) printf ( "string lenght of %s = %dn" , s [ i ], my_strlen ( s [ i ])); return 0 ; } 

He compiles and checks his code and everything works normally. Now he can add these changes to the repository safely.

Git adds active files to the staging area.

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

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

Git is pointing a bookmark question before naming the file. Obviously these files are not part of Git, and that's why Git doesn't know what to do with these files. That's why, Git is pointing a bookmark question before naming the file.

Jerry has added files to the staging area, the git status command will show the files in this area.

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

To commit the changes, he uses the git commit command followed by the -m option. If we forget the -m option. Git will open a text editor, where we can write multiple commit information.

 [jerry @ CentOS project] $ git commit -m 'Implemented my_strlen function' 

The above command will produce the result:

 [master cbe1249] Implemented my_strlen function 
1 files changed, 24 insertions (+), 0 deletions (-)
create mode 100644 string.c

After committing to view the log details, he ran the git log command. It will display the information of all commits with deposit IDs, depositors, commit dates and SHA-1 hash of deposit.

 [jerry @ CentOS project] $ git log 

The above command will produce the result:
