小编Ben*_*ngt的帖子

我创建了一个提交，其中包含要修改的提交消息。我还没有发布提交，所以我可以安全地重写历史。我可以使用 git log 找到，所以我知道它的 sha1 哈希值。如何快速编辑提交？

我在一个小型USB闪存驱动器上运行Linux实时映像,并希望用它来闪存SD卡.对于我的闪存驱动器,图像已压缩得太大,因此我无法将其写入磁盘.我有足够的RAM来缓冲压缩和解压缩的图像,所以我的解决方案是这样的:

$ sudo mount -t tmpfs -o size=2.5G none /mnt 
$ cd /mnt && wget http://example.com/linux.zip
$ cd /mnt && unzip linux.zip
$ sudo dd if=/mnt/linux.img of=/dev/sdb bs=4M

这感觉很麻烦.如何将图像写入SD卡,从存档中解压缩,从互联网下载,而无需在一行中写入任何内容？

我运行git add了一些文件，构成了一组逻辑上独立的更改，对它们进行了其他更改，并使用git add -p. 进行到一半时，我意识到我还没有提交前一组。

的交互式帮助git add -p仅提供以下选项：

Stage this hunk [y,n,q,a,d,/,s,e,?]? ?
y - stage this hunk
n - do not stage this hunk
q - quit; do not stage this hunk nor any of the remaining ones
a - stage this hunk and all later hunks in the file
d - do not stage this hunk nor any of the later hunks in the file
g - select a hunk to go …

我正在寻找以下问题的简单解决方案.

我们在python中有这种用法的for -loop吗？

[2,3,4,5,6,7,8,9,0,1]

我有一个使用while -loop 的实现:

i = 2
while True:
    i = i%9
    if i == 1:
        break
    # payload code here
    i+=1

Travis-CI不会构建我的项目,发出此错误:
