The diff command is a very important tool on Linux to compare the contents of a file, especially to compare two different versions of a file to find where it was changed. Diff prints changes to each row on the command line. The latest version of diff also supports binary files. The diff program's output is called a pat

in the GNU patch implementation. This format is used for linux kernels released in the form of patches.In addition, there are other less-used formats, such as the Normal format, side-by-side comparison mode (side-by-side), ed script and RCS script Mode.. In addition to the side-by-side comparison mode, you can easily observe file differences. Most of the other formats are to be compatible with the old patch format.Ii. Usage of tools1. diff usageDiff

. Binary File Description: binary files can be stored in the patch file in the original way. Diff can be generated (added with the-A option), and patch can also be identified. If you think such a patch file is too ugly, one of the solutions is to use uencode to process the binary file. Diff compares two text files (or directories) in the unit of behavior and

Linux Tour (1): diff, Patch and quilt (bottom) 2 quiltOur own projects can manage all the code with CVS or SVN. But sometimes we use projects that other developers maintain. We need to change some files, but we cannot submit the code directly to the version number management tool. It is inappropriate to rebuild the entire project with version number management tools, because most of the code is maintained by others, such as the Linux kernel. We just w

command to convert Filel into file2. The line numbers (N1,N2) before the letters (a, D, and C) are for file1, and the following line numbers (N3,N4) are for file2. The letters A, D, and C represent additional, delete, and modify actions, respectively.After each line in the above form follows a number of rows that are affected, the line that begins with "" is the first file, and the line that begins with "" is the second file.Diff can distinguish between block and character device files and FIFO

The diff command compares two files and folders, and if you compare two files, two files are compared by line, and if you compare the directories, diff compares the files with the same name under two files, lists the different binaries, common subdirectories, and files that appear only in one directory.Example 1 where 1c1 represents the first row, and C means tha
