diff

Is it possible to use the "diff" tool without having physical files? Something like this: diff "hello" "hell" Adam Rosenfield You can diff standard input with a file by using the special filename - : # diff the contents of the file 'some-file' with the string "foobar" echo foobar | diff - some-file With bash, you can also use anonymous named pipes (a bit of a misnomer) to diff two pipelines: # diff the string "foo" with the string "baz" diff <(echo foo) <(echo baz) See also How can you diff two pipelines with bash? . 来源： https://stackoverflow.com/questions/991722/diff-without-files

I need to compare two minimized Javascript files. Most common diff viewers list differences per line, but this isn't useful when the script is compressed to a few lines. Are there any good tools for comparing minimized Javascript files? Pretty Diff tool will diff two minified files or a minified to a beautified file with a single button click. http://prettydiff.com/ It operates by first minifing

I have got 2 files. Let us call them md5s1.txt and md5s2.txt. Both contain the output of a find -type f -print0 | xargs -0 md5sum | sort > md5s.txt command in different directories. Many files were renamed, but the content stayed the same. Hence, they should have the same md5sum. I want to generate a diff like diff md5s1.txt md5s2.txt but it should compare only the first 32 characters of each line, i.e. only the md5sum, not the filename. Lines with equal md5sum should be considered equal. The output should be in normal diff format. Easy starter: diff <(cut -d' ' -f1 md5s1.txt) <(cut -d' ' -f1

The default patch file viewer is messy (ie. no side by side diff view etc). I tried setting the path of beyondCompare exe in "Settings->Unified Diff Viewer->custom", but beyond compare also behaves same as default diff tool. Is there a way to atleast allow side by side diff in patch files ? If so, what is the method ? My aim is to allow emailing of changes so that they can be reviewed before I commit them :) Mishal I've never found any, but the solution that I usually use is to simply apply the patch file to a pristine checkout of the tree, and then do a "regular" diff (my preferred tool is

Is there a diff tool which can highlight single character edits as such, and not just show the old and new version of the whole line (i.e. the kind of diff StackExchange shows you for edits to a post)? I'd prefer one I could use on the Linux command line as diff in git . You can try, from git diff : git diff --color-word=. Which is equivalent to --word-diff=color plus (if a regex was specified) --word-diff-regex=<regex> . That would transform this git diff : into this one: Images are from the section " Produce more useful diffs " of the article " 30 Git CLI options you should know about "

I need to compare two strings and output the diff in HTML (similar to MS Word "track changes"). Language is C#, this is (not surprisingly) a .NET web app. There are a few similar questions (like this one for PHP/Python ), but no existing question on SO. I don't need a finished project, just anything that will cut out the extra work. I know this problem has been solved at least once. I'm looking to leverage from that starting place (source for an object, just a method, just an algorithm in C#, anything will be useful). Output for the diff needs to be in HTML. There is a C# class available from
