Linux Tour (1): diff, patch and quilt (lower) 2 quilt We can use CVs or SVN to manage all code for our own projects. But sometimes we need to use projects maintained by other developers. We need to modify some files, but we cannot directly submit code to the version management tool. It is not appropriate to use version management tools to reconstruct the entire project, because most of the Code is maintained by others, such as the Linux kernel. We jus

Recently, I started to touch git. Learning to Git diff is always confusing. Git diff compares the difference between the two files. After searching the net on the net, finally found Le answer. There are two cases, one is when there are files in staging area, and the other is no files in staging area. (1) When there are no files in staging area, git diff compare

In practice, by using Git diff to calculate the number of code changes, there is a need to just count certain types of files (files with special suffix names/extensions), such as: Only the variables for files in the current git repo. java,. xml,. c,. cpp. There are two ways to make git count according to the file suffix name and to count the eligible files in each subdirectory. 1. Use the ' *.java ' and ' *.xml ' directly, if your git version is new

comparing files with the same name, the files with different names are treated as new files. For comparison of C program files, diff also provides special parameters (-P, -- show-C-function) to identify the function names of the differences. There are three types of diff output formats: list mode, command mode, and context mode. Command mode can be divided int

I. OverviewDiff and Patch are a pair of complementary tools, mathematically, diff is similar to the difference between two sets, and patches are similar to the and operations on two sets. Diff compares the differences of two files or collections of files and logs them down to generate a diff file, which is also what we often call patch files, which are patches. P
