Git reflog can view all of the operations records for all branches (including commit, rollback, deleted commit action records, and so on). 1 View History version record command: Git reflog: View submit version history after executing the command as shown in figure:
as you can see from the diagram, a lot of row records appear after you execute the command. Each line of records consists of a version number (commit ID SHA), a head value, and an operation description. The version number is in the first column, the head value is in the second column, and the operation description information is in the third column. Version number: Previously mentioned, the version that identifies each operation, such as commit, merge, and so on, is equivalent to uniquely identifying the head value: The same is used to identify the version, but unlike the version number, the head value is relative. When the head value is head, it is represented as the latest version of the submission; head^ is represented as the last version of the latest version; head^^ is represented as the last version of the latest version; head~100 is the latest version of the 100th version. The smaller the head value, the newer the version, the greater the longer the build time. In the image above, we find that the head value is displayed in Head@{0}, Head@{1}, head@{2} ... The smaller the number of the same head value, the newer the version, the larger the number indicating the older the version. Description of operation: This is a record of what kind of operation, as well as the operation of the description of the information written. 2 View history version record--Specify the number of display bars
Also, as with git log, git reflog has the option to control the number of display bars: command: Git reflog-n  after executing the command as shown in figure:
Here, set the number of display bars to 10, After the command is executed, the number of bars displayed is 10 of the specified number of bars.
