Git-刪除文件

在Git中,刪除也是一個修改操做。git

第一步,先添加一個新文件test.txt到Git而且提交:spa

➜  testcase git:(master) touch test.txt
➜  testcase git:(master) ✗ git add test.txt
➜  testcase git:(master) ✗ git commit -m "add test.txt"
[master a3ea391] add test.txt
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 test.txt

通常狀況下,你一般直接在文件管理器中把沒用的文件刪了,或者用rm命令刪了:code

➜  testcase git:(master) rm test.txt 

這個時候,Git知道你刪除了文件,所以,工做區和版本庫就不一致了,git status命令會馬上告訴你哪些文件被刪除了:blog

➜  testcase git:(master) ✗ git status
On branch master
Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

    deleted:    test.txt

no changes added to commit (use "git add" and/or "git commit -a")

如今有兩個選擇,一是確實要從版本庫中刪除該文件,那就用命令git rm刪掉,而且git commitrem

➜  testcase git:(master) ✗ git rm test.txt
rm 'test.txt'
➜  testcase git:(master) ✗ git commit -m "remove test.txt"
[master 359e5b0] remove test.txt
 1 file changed, 0 insertions(+), 0 deletions(-)
 delete mode 100644 test.txt

另外一種狀況是刪錯了,由於版本庫裏還有呢,因此能夠很輕鬆地把誤刪的文件恢復到最新版本:it

➜  testcase git:(master) ✗ git checkout -- test.txt
➜  testcase git:(master) ✗ git status
On branch master
Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    new file:   test.txt

git checkout實際上是用版本庫裏的版本替換工做區的版本,不管工做區是修改仍是刪除,均可以「一鍵還原」。io
