我检查了另一个更新的分支,然后进行了一些更改,切换回主git,现在更改消失了!我能把它们还给他们吗？终端基本上是:

$ git commit
[detached HEAD 7c09e17] Fixed some stuff
  files changed, insertions(+), deletions(-)
$ git push master
fatal: 'master' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
$ git checkout master
Previous HEAD position was 7c09e17... Fixed some stuff
Switched to branch 'master'
$ git merge theother/directory
