* What is version control

(Scene one)

Is you write a c++/c language project "I have only learned C + + and C language" (probably very big, need a lot of people to write) but you and your little partner can not succeed at once, right, certainly in the process of development, the current project needs to be continuously optimized, the first version of the bug may be patched by a second version , and then a new bug arises, and if you produce a third version, but you have a more serious bug, you may want to (wtf!!! And then your second version is important, and you can submit each update to GitHub to help you manage it ~ ~ ~ ~

(Scene II)

Spicy chicken, such as me and my small partners, may also not touch the big project, at this stage, we are in the process of writing a small program to exercise their own way of the great God, spicy problems come, there is no feeling to write a lot, but in the time of the search is very laborious, and sometimes the hands of cheap, in storage space, We will be particularly painful to delete a long time before the program,GitHub can help you to write each program to manage and retain, leaving you a clear world ~~~~~~650) this.width=650; "src=" http// Img.baidu.com/hi/jx2/j_0069.gif "alt=" J_0069.gif "/>

Prehistoric Times: diff and Patch

Diff:diff command (difference) to compare the differences between two text files or directories

Eg:diff-u Hello World>diff.txt

Explanation: Compare the differences between the Hello file (original file) and the world file (the destination file) to save the diff

Patch:diff Anti-operation

EG:CP Hello World

Patch-r World<diff.txt
