How to highlight the differences between subsequent lines in a file?

阅读更多关于 How to highlight the differences between subsequent lines in a file?

问题 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? 回答1: I wrote a Python script

Equivalent of linux 'diff' in Apache Pig

问题 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? 回答1: I use the

Mercurial extdiff one at a time

问题 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? 回答1: Like explained in Mercurial: The Definitive Guide, extdiff creates two snapshot of the source tree and call the diff

Diff/compare two files by file descriptor (fd) instead of file name

阅读更多关于 Diff/compare two files by file descriptor (fd) instead of file name

问题 Is there any way in Linux, using c, to generate a diff/patch of two files stored in memory, using a common format (ie: unified diff, like with the command-line diff utility)? I'm working on a system where I generate two text files in memory, and no external storage is available, or desired. I need to create a line-by-line diff of the two files, and since they are mmap 'ed, they don't have file names, preventing me from simply calling system("diff file1.txt file2.txt") . I have file

VIM - Passing colon-commands list via command-line

阅读更多关于 VIM - Passing colon-commands list via command-line

问题 Good day, I am writing a simple script within my BASHRC file to accommodate something I couldn't quite resolve in a previous question: Side-by-side view in Vim of svn-diff for entire directory I basically generate a list of all files which have a "Modified" SVN status. For each of these files, I want to create a side-by-side visual diff, convert it to HTML, then append it to a running HTML file. eg: MODIFIED_FILES="$(svn status | grep "^M" | cut -c9-)" for i in ${MODIFIED_FILES}; do #

Github style split diffs on a command-line

阅读更多关于 Github style split diffs on a command-line

问题 Github introduced split diffs in September. Is there any way to see that on a command-line? 回答1: A typical command line is usually not wide enough to handle this kind of comparison. Note that most of Git is built for 80 character wide terminals. So you would have about ~35 characters per side; I doubt that’s helpful (I already have problems reading unified diffs on a much wider terminal). Git however gives you the ability to use diff tools, external programs that can do whatever diff you

Get changed files from svn command line between two dates

阅读更多关于 Get changed files from svn command line between two dates

问题 I need to get the changed files list between two dates in SVN. I have used the below command.. svn diff -r{2011-10-12}:{2011-10-28} --summarize https://svn.blah.com/../ > output.txt from some reason the files modified on 28-10-2011 are not populated in the output text file. Could please give the exact command to extract the files list between the two dates (inclusive of from and to dates) 回答1: this is normal, when you give the date {2011-10-28} it means "on midnight"... thus specify one day

Measuring “closeness” in large source trees

阅读更多关于 Measuring “closeness” in large source trees

问题 As part of a question I posed earlier about finding the best match between two sources, where one has an active git repo and the other has no git history, I wrote a perl script to find the closest git commit. I'm in the process of rewriting the script so that you don't have to guess at which branch to use, but it will run through and find the closest match in all branches, then tell you the best commit with the best branch. Unfortunately, I'm finding that the measurement I'm using may not be
