I'm looking for a way in SmartGit to select all files across multiple commits. In essence, I need a list of every file that has changed between commit A and commit C, including the files from commit B. I was also looking for a way to copy the relative file path of every changed file, but the file view only allows the option to select the relative file path when only a single file is selected. As soon as I select more than one file, my ability to copy their file paths disappears.
Any ideas? Thanks!
Select the commits A and C in log window. In the Files list you can see all files. Then press Ctrl-C.

I want to keep my database updated, so every time I get the latest files from TFS I want to find the changed files (newest in date) in order to run them and not run ALL of the files.
I want to create a batch file to search, find and copy them to a temp folder so I'll be able to run only them.
A creative solution would be you can enter dir results into a text file and then whichever language you are using just do string slicing which can give u date, memory and name of the file. This is command- dir/a>file replace file with the text file. if u want the text to be entered into the file in append mode then dir/a>>file
I am working with a tool which auto-generates a large amount of C code. The tool generates code for a batch of .c and .h files at each run. For some reason, the tool isn't smart enough to recognize when the files have no substantial changes, so in many cases it simply updates a timestamp in the comments at the top of each file. Otherwise, the file remains unaltered.
When I run git status in that scenario, I sometimes see dozens or hundreds of files changed. But as I review the changes to the individual files, most of them have no real changes - just an update to the timestamp. I have to go through each file one-by-one to determine if there are any actual changes to be committed.
Is there a way to configure Git so that it can ignore inconsequential changes such as the timestamp in the header comments? Or how might I otherwise deal with this situation?
Thanks for your help.

Yes; this is the purpose of a filter.
You might be familiar with git's notion of "clean" and "smudge" filters already, that's how it handles line ending conversion. When you are on a Windows computer and have Windows-style line endings in your working directory, you might set a .gitattribute like * text=auto indicating that you want files checked into the repository with "normalized" Unix-style line endings. In this case, the files will have the "clean" filter applied to convert \r\n line endings to \n style line endings. Similarly, the files will be "smudged" on checkout to convert from \n to \r\n on-disk.
You can create your own clean and smudge filters to remove (or add) data when translating between the working directory and the repository. For these files you can add an attribute:
*.c filter=autogen
And then you can configure your autogen filter, with commands to run in the "clean" (into the repository) and "smudge" (into the working directory) directions.
git config --global filter.autogen.clean remove_metadata
git config --global filter.autogen.smudge cat
(Using cat is a "noop" as far as filters are concerned).
The Pro Git book has more detailed examples of creating your own filters.
I discovered a way to address the problem of trivial changes using Beyond Compare. I will describe the process as it pertains to ignoring timestamp updates in auto-generated C files, but it can be easily adapted to other situations and languages:
Configure Beyond Compare as the Git difftool. See here for specific details about how to do this.
(Optional but helpful) Add a Git alias for the git difftool --dir-diff --no-symlinks command (for example, dtd).
Make some changes (e.g. auto-generate your files), and run git dtd to do a directory diff. Beyond Compare will open and show you a before/after Folder Comparison of your changes.
Open a Text Compare session window for one of your changed files. Open the Tools menu and select File Formats.
Open the Grammar tab, delete the "Comments" grammar element.
Add a new grammar element and give it a meaningful name such as "Generation Time Comment".
For Category, select the "Delimited" grammar element. In the "Text from" box, enter the text you would like to ignore. For example, if the timestamp in your auto-generated code starts with the string * Generation Time:, enter it into the "Text from" box. Check the "Stop at end of line" checkbox.
Click the "Save" button and go back to your Text Compare session window.
Open the Session menu and select Session Settings. Open the Importance tab.
Look for your new grammar element (e.g. "Generation Time Comment") and uncheck it. This will tell Beyond Compare to treat it as an unimportant change.
Open the Comparison tab, select Rule-Based Comparison.
Change the dropdown at the bottom of the dialog to Update session defaults.
Close Beyond Compare, and then reopen it again by running the git dtd command.
All of the files in the Folder Compare session which contain nothing but an update to the timestamp will be shown with unimportant differences. If you want to completely hide files with unimportant differences, toggle off Ignore Unimportant Differences in the View menu.

I want to get list of files and directories affected by specific commit. I have no problem getting the commit itself but I rather don't know how to get affected files and directories.
Just to make it clear I need something like this:
file x - deleted
file y - added
file z - modified
Git is snapshot-based; each commit includes a full list of files and their state. Any notion of "affected" files needs another commit to compare it to. This is commonly done against its parents, which seems to be what you're asking about. You can figure out which files are different between two commits (or more exactly, their trees) by using the git_diff family of functions.
You can find an example of doing so in the examples listing for libgit2. There is also a more general annotated diff example. The second link also shows how to list individual files as well as their contents, if you need that. Check the reference for a a full listing of available function to work with diffs.
Note that this won't give you affected directorires by itself, as Git does not track directories, but only files.
You're looking for git diff.
The same function exists in libgit2, and the documentation for it is here.
If you're analyzing older commits, "git diff [commit1] [commitAfterCommit1]" will give you a list of changes that the second commit made from the first. You could prune this output to get yourself just the changed file names.
In Clearcase, I want to copy (fork, split) a file while preserving its history. Something like svn cp old.txt new.txt. How do I do it?
It isn't possible do fork a file in ClearCase.
If you refactor your code and split a file in two, one of them will appear as a new file and you will loose the information about who coded it. The annotate command will say the author of the lines are who splited it.
UCM or not, you cannot duplicate easily the full history of a file.
The best way to isolate an history is still to create a branch in order to make new versions to that file without impacting the same file in the original branch.
Thinking 'svn cp' should be available in ClearCase might come from the fact that, in SVN, branches are directories, and a tool like cc2svn will actually replicate ClearCase branches using 'svn cp'.
But since, with ClearCase, branches are first-class citizen, it is best to reason in term of branch than in term of copy/fork.
From the main page of cc2svn:
There is a difference in creating the branches in ClearCase and SVN:
SVN copies all files from parent branch to the target like: svn cp branches/main branches/dev_branch
ClearCase creates the actual branch for file upon checkout operation only.
Pretty simply done
Check out parent folder
Move element you wish to duplicate to appropriate location (not within the checked out parent folder)
Undo Checkout of parent folder
All the files get returned to the original folder with history and also the duplicate ones remain in the new location with the history too. Now each file can be checked out and changed individually
I have an exe that I can drag and drop another file onto to produce a third file. Unfortunately it seems to accept only 1 file at a time, if I select multiple and drop it doesn't seem to work.
How do I create a batch file to automate the process of dragging a thousand files of .drag extension onto drop.exe?
Thanks!
In Windows, dropping a file on an exe just executes the command line:
fileprocessor.exe "<full path to dropped file>"
So you should be able to just call the exe directly in your batch file, passing the path to each file that you'd like to process.
EDIT: Look into the For batch command to do this for a series of files. You should be able to specify the wildcard and then call the command for each.
For %%a in (*.drag) do fileprocessor.exe "%%~fa"
Evidently, batch files can have multiple objects dropped onto them. See this question. You should be able to adapt the answer to your needs. I do wonder if there is a maximum number of characters that can be passed in, though, so you might not be able to drag thousands of files onto it. Possibly not even hundreds. But definitely multiple.
EDIT: In your comment to dmercredi's answer, you mention wildcards. If you don't need the drag/drop capability and just want to specify *.drag in your batch file, check out this question instead. There are a variety of answers there that may suit your needs.
