1、查看代码状态
git status
2、添加修改的文件
git add .
3、提交添加的文件
git commit -m "注释"
4、提交到git仓库
git push
5、合并
git merge branch_name
6、更新
git pull
如果在第一次创建ssh的密钥匙设置了密钥，之后忘记了或者嫌每次输入密钥太烦，那么重置密钥的方法在此：
Mac下
1、查看本地ssh keys文件是否存在，可以看到id_rsa和id_rsa.pub就是之前创建的密钥对。
$ ls -al ~/.ssh
total 24
drwx------ 5 {user} staff 160 2 27 15:18 .
drwxr-xr-x+ 27 {user} staff 864 3 18 11:30 ..
-rw------- 1 {user} staff 3243 3 18 17:06 id_rsa
-rw-r--r--@ 1 {user} staff 748 3 18 17:06 id_rsa.pub
-rw-r--r-- 1 {user} staff 196 2 27 15:18 known_hosts
或者
$ cd ~/.ssh
$ ls -al
total 24
drwx------ 5 c{user} staff 160 2 27 15:18 .
drwxr-xr-x+ 27 {user} staff 864 3 18 11:30 ..
-rw------- 1 {user} staff 3243 3 18 17:06 id_rsa
-rw-r--r--@ 1 {user} staff 748 3 18 17:06 id_rsa.pub
-rw-r--r-- 1 {user} staff 196 2 27 15:18 known_hosts
2、重新创建ssh keys，主要执行第一行命令，输入邮箱，Overwrite输入y，下面一顿回车完事儿，这时候就生成了新的ssh keys。
$ ssh-keygen -t rsa -b 4096 -C "{your email}"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/{user}/.ssh/id_rsa):
/Users/chen.yingjie/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/{user}/.ssh/id_rsa.
Your public key has been saved in /Users/{user}/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:NnhL9fyyyjVjZXDMBpg3vVlxWEx50EnJ03fZNE {your email}
The key's randomart image is:
+---[RSA 4096]----+
| o..+##|
| ...o=B=|
| . . o ++ o|
| + o + |
| . * . |
| . o = |
| o.. |
+----[SHA256]-----+
3、到gitLab设置新密钥：
$ cat id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQDBrosq5Th4A8x+rjX5hVJjR9oJyf0VyH+Rx1lA3LFeZ5iq7T3Q994rNJdMKqed4N4xL6KhE9HwSqekMh5D132geyDjsr4DWYzsen0OVvJDir7nqJdKTKhAUW04zTmeyRYl0nqWC3R4OBLuG1MNXr3mQ1ns9JIyluzm6eL4YUMkakEL02KhVDTCs+p45Y1t6ETL7jL6/+/FYa9jyPiqxZGo2aESbFBUIB8TFpKt5kZfH7/h7k2GCBiFpqMliNMYduvHoJqIRAVQTclSXE0jxh3JDjzSf8xEryNpcs/aXXTHxsnUuR6C1AxcuFy2ZO0I5XdM2ve1Zx/kkAcHX16phFmJrUX/5lIjXSRpvsRZ1PN7K3mhCjWyoQ== {your email}
打开gitLab
把上面邮箱前的一堆复制到框中，title自定义，原来的可以删除(右下角)。
新密钥设置完毕。
