diff

问题 On the diff man-page I've found these exit values: 0 No differences were found. 1 Differences were found. >1 An error occurred. Are there different exit values above 1 for different errors? 回答1: It depends on your diff command. Mine (GNU diffutils 3.0) says: An exit status of 0 means no differences were found, 1 means some differences were found, and 2 means trouble. Normally, differing binary files count as trouble, but this can be altered by using the -a or --text option, or the -q or -

问题 At this moment, I am managing a piece of software that has multiple XML configuration files. When a new version of software is released, sometimes the base config files change, we currently have the software call KDiff on startup. If it detects a change, it prompts the user to choose the changes. The problem with this approach is that KDiff is a line comparing program and not aware of the ways of XML (like Nodes, etc.) Ideally, I would like to programmatically work with a library in C# (since

问题 I am comparing 2 large CSV file using Perl that's called in a batch file. I put the result in a 3rd file. Currently the file contains other information like headers, and other lines like this: --- file1.txt Wed Mar 7 14:57:10 2018 +++ file2.txt Wed Mar 7 13:56:51 2018 @@ -85217,4 +85217,8 @@ How can the result file only contains the difference ? Thank you. This is my perl: #!/usr/bin/env perl use strict; use warnings; use Text::Diff; my $diffs = diff 'file1.txt' => 'file2.txt'; print $diffs;

问题 I'm trying to use git diff to find differences between two version of a certain file type if the following expression has been added or deleted: (****) According to the git diff Documentation the parameter -G is what I'm looking for. So I tried the following: git diff -G '\(\*\*\*\*\)' -- *.fileEnding Unfortunately it doesn't work and all other differences in the files are returned too. I'm not very familiar with regexs btw. EDIT: I think need to be a little more specific about my issues:

问题 I am creating a file and then doing diff on it. I want to do diff on the file which iscreated in previous step but i get the error that file dont exist . This is my code os.popen("mysqldump --login-path=server1_mysql -e --opt --skip-lock-tables --skip-extended-insert -c %s > %s.sql" % (database, filename)) os.popen("diff %s %s > %s" % (weekly, filename, filename+".PATCH")) 回答1: os.popen() has been deprecated since version 2.6. However, to get your code working, you should wait for the first

问题 I would like to generate diffs for the sake of doing incremental backups of an sql database. Using the standard unix 'diff' tool generates unnecessarily large files, since they include the full text of deleted lines. I only need support to be able to patch in one direction (to generate the current db dump from the full dump and an incremental patch). How would I go about doing this? I have tried so far using diff -e and patch -e, but it doesn't seem to be working correctly, as the resulting

问题 How to force git merge to generate conflict on all file or all file that differ to generate conflict having whole old and whole new version, example of such file : <<<<<<<<<<A A B C D OLD OLD OLD E F G ... Z ============ A B C D NEW NEW NEW EEEEEEE FFFFF GGG ... Z >>>>>>>>>>B The idea is that I would like to merge manually having whole contents of two files, no metter if lines are identical or one branch is inheriting from whole previous, example: $ echo ABC > file $ git add file $ git commit

问题 I want to do a diff over two xml files but ignore 2-3 line patterns. eg: Say I want to ignore availability & price while comparing the xml format below. Here is what I have so far: diff -I '^<PRICE>*' 1.xml 2.xml <CATALOG> <PLANT> <COMMON>Bloodroot</COMMON> <BOTANICAL>Sanguinaria canadensis</BOTANICAL> <ZONE>4</ZONE> <LIGHT>Mostly Shady</LIGHT> <PRICE>$2.44</PRICE> <AVAILABILITY>031599</AVAILABILITY> </PLANT> </CATALOG> Using the above diff, it skips the price but how do I add availability to

问题 Visual Studio has a fantastic internal diff tool: https://www.visualstudio.com/en-us/docs/tfvc/compare-files I'm using Perforce in Visual Studio via the P4VS plugin. The plugin adds the "Diff" sub-menu when you right-click on a file's tab. But by default any diff operations are carried out by P4M, rather than using Visual Studio's internal diff tool: To it's credit, P4VS does allow for the selection of a different diff app. But the provision is for a command line operation. I don't know how
