diff

I want to be able to do a standard diff on two large files. I've got something that will work but it's not nearly as quick as diff on the command line. A = load 'A' as (line); B = load 'B' as (line); JOINED = join A by line full outer, B by line; DIFF = FILTER JOINED by A::line is null or B::line is null; DIFF2 = FOREACH DIFF GENERATE (A::line is null?B::line : A::line), (A::line is null?'REMOVED':'ADDED'); STORE DIFF2 into 'diff'; Anyone got any better ways to do this? I use the following approaches. (My JOIN approach is very similar but this method does not replicate the behavior of diff

I am using winmerge as my extdiff tool, like this: [extdiff] cmd.winmerge = C:\Program Files\WinMerge\WinMergeU.exe opts.winmerge = /e /x /ub /wl The thing is, when I run hg winmerge it seems that it sends all of the files at once, while for example in Git, when I do a diff it calls the difftool with one modified file at a time. Can I get the same behaviour in Mercurial? Like explained in Mercurial: The Definitive Guide , extdiff creates two snapshot of the source tree and call the diff tool on them. You're tool has to support directory diff for it to work, but like explained, you can use

I have a small issue with Windows permissions (or rather, I'm trying to troubleshoot an issue which I think has to do with Windows permissions) and would like to compare and contrast permissions on different machines (one does not have the issue and one does), is there a tool that can do this for me? Or some hidden functionality that I don't know about? In Linux I'd do ls -l, dump it into a file and use the diff command, what about Windows? David Try the cacls utility ( cacls /? for usage). There are a couple of different versions, depending on your version of Windows be it XP, Vista, 7, or 8,

I do a lot of urgent analysis of large logfile analysis. Often this will require tailing a log and looking for changes. I'm keen to have a solution that will highlight these changes to make it easier for the eye to track. I have investigated tools and there doesn't appear to be anything out there that does what I am looking for. I've written some scripts in Perl that do it roughly, but I would like a more complete solution. Can anyone recommend a tool for this? I wrote a Python script for this purpose that utilizes difflib.SequenceMatcher : #!/usr/bin/python3 from difflib import

Using msysgit on windows, whenever I do git diff on a repository that has a submodule or several, the command prompt (and also PowerShell) crash. Is this a known but and is there a fix/workaround? Can I exclude submodules from diff? Also: PS Z:\www\gittest> git --version git version 1.7.6.msysgit.0 EDIT: This has also been reported on the msysgit google group. I can't reproduce such issues with diff and submodules, but if you don't care about submodules diff, you can do: git diff --ignore-submodules I fixed this by installing Microsoft kb2458000 (The conhost.exe process crashes when an
