One could try something like:

Code:

#!/bin/ksh
destination=/destination/directory
left=3000000000
source=/source/directory

if ! cd "$source"
then	exit 1
fi
ls -ltr | grep '^-' | while read _ _ _ _ size _ _ _ name
do	if [ $size -lt $left ]
	then	left=$((left - size))
		printf 'Moving "%s", size: %d, looking for %d more.\n' \
		    "$name" $size $left
		echo mv "$name" "$destination"
	else	printf 'File "%s", size: %d, too big to move this time.\n' \
		    "$name" $size
	fi
done

If you change the values assigned to destination and source to pathnames to the destination and source directories you want to use and run the code as it is above, it will tell you which files it would select from the directory named by source to be moved to the directory named by destination, show you the sizes of the files being moved, and show you the mv commands that would be issued to move those files (without actually moving anything). If you try that and it looks like it is doing what you want, you can remove all of the code shown in red and the script will just silently move the oldest files it can find as long as the total size of the moved files is less than 3000000000 bytes.

git-mv

GIT-MV(1)							    Git Manual								 GIT-MV(1)

NAME

       git-mv - Move or rename a file, a directory, or a symlink

SYNOPSIS

       git mv <options>... <args>...

DESCRIPTION

       Move or rename a file, directory or symlink.

	   git mv [-v] [-f] [-n] [-k] <source> <destination>
	   git mv [-v] [-f] [-n] [-k] <source> ... <destination directory>

       In the first form, it renames <source>, which must exist and be either a file, symlink or directory, to <destination>. In the second form,
       the last argument has to be an existing directory; the given sources will be moved into this directory.

       The index is updated after successful completion, but the change must still be committed.

OPTIONS

       -f, --force
	   Force renaming or moving of a file even if the target exists

       -k
	   Skip move or rename actions which would lead to an error condition. An error happens when a source is neither existing nor controlled
	   by Git, or when it would overwrite an existing file unless -f is given.

       -n, --dry-run
	   Do nothing; only show what would happen

       -v, --verbose
	   Report the names of files as they are moved.

SUBMODULES

       Moving a submodule using a gitfile (which means they were cloned with a Git version 1.7.8 or newer) will update the gitfile and
       core.worktree setting to make the submodule work in the new location. It also will attempt to update the submodule.<name>.path setting in
       the gitmodules(5) file and stage that file (unless -n is used).

BUGS

       Each time a superproject update moves a populated submodule (e.g. when switching between commits before and after the move) a stale
       submodule checkout will remain in the old location and an empty directory will appear in the new location. To populate the submodule again
       in the new location the user will have to run "git submodule update" afterwards. Removing the old directory is only safe when it uses a
       gitfile, as otherwise the history of the submodule will be deleted too. Both steps will be obsolete when recursive submodule update has
       been implemented.
