问题 I wanted to produce a side by side SVN diff instead of the usual SVN diff output. Is there any way to get this sort of output ? 回答1: You can specify a custom diff command: svn --diff-cmd "diff" --extensions "-y" diff (Or then perhaps even use tools like sdiff) 回答2: cdiff can display side by side , incremental , and colorful diff, see its home page for detail and demo at https://github.com/ymattw/cdiff 回答3: svn diff --diff-cmd 'diff' -x '--side-by-side -W230' FILENAME Tune the "-W230" to

问题 I am writing a bash script, and I would like to know which files are the same in two directory trees. It would be the opposite of using diff. Well i found the answer myself. I had tried it before, but I thought it did not work. diff -srq dir1/ dir2/ | grep identical 回答1: Well i found the answer myself. I had tried it before, but I thought it did not work. diff -srq dir1/ dir2/ | grep identical What -srq means? From diff --help : -s --report-identical-files Report when two files are the same.

问题 How can I get output like in git diff --color-words , but outside Git? Closest thing is wdiff -t , but it underlines/inverts things instead of using green/red colours and does not allow specifying my whitespace regex. 回答1: git diff --color-words --no-index 回答2: According to a comment from Jefromi you can just use git diff --color-words file1 file2 outside of git repositories too. 回答3: Git version 1.9.1: git diff --word-diff=color fileA fileB 回答4: you can say git diff --color=always --color

问题 Suppose I have two tables, t1 and t2 which are identical in layout but which may contain different data. What's the best way to diff these two tables? 回答1: Try this: (select * from T1 minus select * from T2) -- all rows that are in T1 but not in T2 union all (select * from T2 minus select * from T1) -- all rows that are in T2 but not in T1 ; No external tool. No performance issues with union all . 回答2: You can try using set operations: MINUS and INTERSECT See here for more details: O'Reilly -

问题 I have a working copy of a repository on my machine, and I know that it has been updated on the server. I would like to know how to get the difference between the new version and the version in my working copy by using svn command line arguments. Is there a way for me to do this? 回答1: The working copy is revision BASE. The latest copy from the repository is revision HEAD. This will compare your working copy against the HEAD revision: svn diff -r HEAD <file> Actually that'll spit the changes

问题 I have two arrays: var a1 = [ { ID: 2, N:0 }, { ID: 1, N:0 } ]; var a2 = [ { ID: 1, N:0 }, { ID: 2, N:0 }, { ID: 3, N:0 } ]; I need to get all elements that are on a2 but not in a1 . An element here is distinct of another only by the property ID , the other properties should be ignored. And I cannot guarantee the order of the elements on the arrays. Meaning the result for this example should be: var result = [ { ID: 3, N:0 } ]; // result for the example above How can I do this in an efficient

问题 I need git diff functionality for 2 files that I have outside of any repository. Is there a way to do it? Something like git diff --file1 /path/file1.txt --file2 /path/file2.txt If not, what may be an alternative solution? 回答1: The answer is right in the git diff documentation (though I admit it's easy to miss): git diff [<options>] --no-index [--] <path> <path> This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a

问题 If I do this: svn diff --summarize --old http.../svn/project/trunk --new http.../svn/project/branches/branch I get a list like this: D http.../svn/project/trunk/deletedFile A http.../svn/project/trunk/addedFile M http.../svn/project/trunk/modifiedFile It only shows the old paths. Is there a way to get the new paths as well? I'm parsing this output, and I'd like to get these paths: http.../svn/project/branches/branch/deletedFile http.../svn/project/branches/branch/addedFile http.../svn/project
