FILEMERGE allows manipulation of binary data files that are in the ’dorgbn’ format. You can extract one or more ’columns’ of data from a file, duplicate columns from a file, or combine parts of different files. This routine is based on the UCLA program DORGBN.

Funny, that - I just played with BBEdit’s differences tool this weekend after updating to MOSX 10.2.4 (I had to restore my changes to the Apache config). I knew it was there and had used it before, but to manually apply or just to check changes. Pretty much the same - it snaps the windows side by side and has buttons to apply changes to the old or new files. Don’t know if Apple’s tool can compare whole folders tho. Of course, BBEdit isn’t free, but if you already have it and do all your text editing with it, that’s one less tool to worry about.Don’t know if Apple’s tool can compare whole folders tho.
Yup, it can. --Andy
Wow, I had no idea that BBEdit had a file comparison tool. So I checked it out, and it sucks. FileMerge.app is a much better tool, the graphic indication of changes makes everything work so easily.
guys!!! help!! i still cant find the location to download FILEMERGE. i have looked everywhere and on apple’s developers site. can someone help me out with a link pretty pleeeeaaaassssee
This is a great tool for fixing the Apache conf issue that arose in teh last OS X update.
If you use emacs, give ediff a try. Colored highlighting of difference regions and the ability to update one file from the other. You can also compare 3 files. With undo.
Just to add more details: Emacs lets you do diffs on regions, as opposed to just on files, so you can focus on areas of special interest and leave the confusion of the rest of the file untouched (this also implies that you can diff regions within the same file). It’s also possible to refocus a diff marked section, or even explicitly choose to do a diff down to word level coloring, which is very handy.I recently discovered that VIM has got a diff mode, too. Some key features:
*view differences of up to three files in seperate windows
*windows scroll synchronously in diff-mode
*hiding (folding) of equal lines
*easy copying of differences from one file to another
*invocation from within shell prompt
*can patch current file with existing diff file To learn more about vimdiff type :help diff at vim prompt.
I’ve grown to really appreciate FileMerge for editing purposes. I help a friend with editing his story, and FileMerge helps me zone in on his precise changes between drafts of a story. Invaluable!

You’re looking for xcode, an entire suite of development and utility tools. If you have the CD for the OS you’re running, you’ll find it in the ’optional installs’ folder called simply ’xcode’

Filemerge: Tool to merge small HDFS filesProject descriptionFilemerge
Filemerge is a utility for merging a large number of small HDFS files intosmaller number of large files. Filemerge is intended for use by Hadoop operationsengineers and map-reduce application developers.
The structure of the code is simple. The actual merging is performed by a Pigscript created at run time using user-supplied parameters. These parameterscontrol the set of files to merge. The utility consists of a single file,filemerge.py, that takes the input parameters and invokes the created pigscript. As such, pigcommand needs to be available and in path of theruntime user. The user specifies the input path, output path, topic, andfiles to be merged either as a year/month/day format or specific HDFS directoryor a list of HDFS directories in a file.Installation and testing
Because the application code is small and self-contained, installation requiressimply cloning the repository.
Note that filemerge itself does not have any dependencies besides pigcommand-line. However, running the test suite locally requires installation ofthe test discovery and mocking packages. These dependencies are listed infilemerge/requirements.txt and can be installed as follows.
Finally, installation can be verified by running the test suite locally.
Developers can check test coverage running
from the project top-level directory.Running the scriptThe script API
The full API of the script is available on commandline by typing
The help message is reproduced below for reference.
The arguments outside the square brackets are required and those in the squarebrackets are optional, but a minimum set of these arguments is needed to computethe set of directories to be merged. The acceptable option groups are following:
*Group 1
*year (-y)
*year (-y), month (-m)
*year (-y), month (-m), day (-d)
*Group 2
*HDFS directory (-D)
*Group 3
*file with a list of HDFS directories (-f)
*Group 4
*window with a start date (-w); files for all days between start date minuswindow to start date will be merged
*Group 5
*lookback with a start date (-l); files for a single day lookback days before thestart date will be merged
These option groups are designed to enable merging at the directory, day, month,or the year level. The -f offers ability to merge non-contiguous firectoryblocks. The -w and -l options allow merging of directories at periodicintervals using a sliding window.
One can further enhance the flexibility of these options by wrapping thepython call in a shell script and providing custom list of directories,non-contiguous months, shunking large directory lists into smaller parts etc.Why all the flexibility?
The filemerge tool is written with operations and map-reduce applicationdevelopers in mind. Operations team will need periodic merges based on theretention policy and will typically use the tool with the -y,-m,-doptions. Map-reduce application developers might need to merge singledirectories or random directory groups and will use the -d and -foptions.Basic usage: Merging all files in a directory
The most common usage pattern for filemerge is to merge all files in adirectory and produce one output file (in a different directory). To merge filesunders a specific directory, provide the basepath using the -i option andthe final directory name using the -D option. In the following invocationthe /path/to/clickstream is the base HDFS path and jan2016 is thesubdirectory that contains the files to be merged (in this case, for January2016). In other words, the full path to the files that will be merged is:/path/to/clickstream/jan2016Example invocation for a full month merge
Following command invokes the script for merging February 2015 data of the‘clickstream’ directory in HDFS. This is the raw call to the filemerge python scriptand will initiate 28 map-reduce jobs.Example invocation for a full year merge
Simply omit the month and day options and the merge wil be performed for thefull year. Following command invokes the script for merging the entire 2015 dataof the ‘clickstream’ directory with a 1 day chunk size. This will initiate 365map-reduce jobs.
Note that detecting files in time window (e.g. a certain month or a year)requires filemerge to assume certain directory naming conventions. Thisconvention is specified in filemerge/templates.py and can be user-defined.Example invocation for a non-contiguous directory list
To merge files under unrelated non-contiguous directories, list all the finaldirectory names in a file and pass the full file path to the -f option. Inthe invocation below, -i captures the common portion of the path to all thedirectories and the final directories are listed in the file.
Lets assume to that /local/filesystem/path/to/directory_list.txt containsthe following linesFilemerge Windows
In that case all files under /hdfs/path/to/clickstream/{d_20150225,d_20160309, d_20150728} will be merged. Note, that they wont be merged intothe same file. Rather, three different output directories, one for each directoryin listed in directory_list.txt, will be created.Example invocation for a sliding time windowFilemerge
The following invocation the filemerge script will merge files in theclickstream directory for the last 20 days (not including today). The windowis datetime aware.Example invocation for a sliding window daily merge
The following invocation the filemerge script will merge files in theclickstream topic for the day 20 days prior to today. The lookback isdatetime aware.Multi-directory merge
For multi-directory merges, filemerge.py can be called from a script thatprovides the list of directories and the merge frequency. The following wrapperscript shows how to merge 2015 files for a subset of directories. The script needs tobe present in the same directory as the filemerge.py script.Merge for custom months
Merging for custom months is straightforward and is similar to above loopinglogic. Once again, the following script needs to be located in the same directoryas filemerge.py.High-level pattern
The overarching pattern here is to realize that the unit of time for the mergelogic is a directory. As long as this is noted, the actual logic can be customizedin more ways than those shown above: simply write a wrapper shell script tocreate your variables and loop over them. These variables can be months,input directories, or output directories.Release historyRelease notifications | RSS feed
