在当前目录中查找已签出代码的大小

Question

I want to find the size of the current checked-out files in a folder/project, but ignore the git directory.

Something like:

du . --ignore '.git'

Is there a way to find the size of all the files ignoring what's in the .git folder? When I do this:

du . --exclude='.git'   
du . --exclude='./.git'  # or this

Either way, I get:

du: --exclude=./.git: No such file or directory

What do I do?

Answer 1

If your du has no --exclude option, you have two easy ways you can deal with this. This first one assumes that there are no hard-links between files in .git and files elsewhere in the tree, but that's usually true:

• run du to get the total usage
• run du on .git itself to get the .git usage
• subtract the second number from the first number

The second easy way is to install a version of du that does have --exclude .

There is a third way to handle this, which is also pretty easy but a little tricky: just move .git out of the way:

mv .git ../save-git
du ...
mv ../save-git .git

If you use this method, make sure nothing is trying to do anything Git-like in between. Or, make .git a symbolic link to ../save-git , or (if your Git is new enough) a plain-text file containing a redirect. Both of those methods can mess with the total, but only by one disk-block worth of space (the symlink or plain-text direct takes a disk block, unless the OS / file-system uses in-inode symlinks and the symlink is short enough to fit in-inode).

Answer 2

For whatever reason (likely the BSD history of the Mac's utilities), the macOS version of du does not include --exclude . However, at least as of 10.14.x, it does include the much-less-obviously-named -I option which ignores items that are in the "mask" that is provided--in this case "mask" is just another name for some form of regular expression which at least takes simple * and ? wildcards.

Running

 du -I .git .

gives the size heirarchy, and

 du -s -I .git .

gives the summary. In both cases, the .git directory is ignored.
