git how to fork

To view Git commit history, use the gitlog command. 1. The basic usage is gitlog, which can display the submission hash, author, date and submission information; 2. Use gitlog--oneline to obtain a concise view; 3. Filter by author or submission information through --author and --grep; 4. Add -p to view code changes, --stat to view change statistics; 5. Use --graph and --all to view branch history, or use visualization tools such as GitKraken and VSCode.

To delete a Git branch, first make sure it has been merged or no retention is required. Use gitbranch-d to delete the local merged branch. If you need to force delete unmerged branches, use the -D parameter. Remote branch deletion uses the gitpushorigin-deletebranch-name command, and can synchronize other people's local repositories through gitfetch-prune. 1. To delete the local branch, you need to confirm whether it has been merged; 2. To delete the remote branch, you need to use the --delete parameter; 3. After deletion, you should verify whether the branch is successfully removed; 4. Communicate with the team to avoid accidentally deleting shared branches; 5. Clean useless branches regularly to keep the warehouse clean.

To add a subtree to a Git repository, first add the remote repository and get its history, then merge it into a subdirectory using the gitmerge and gitread-tree commands. The steps are as follows: 1. Use the gitremoteadd-f command to add a remote repository; 2. Run gitmerge-srecursive-no-commit to get branch content; 3. Use gitread-tree--prefix= to specify the directory to merge the project as a subtree; 4. Submit changes to complete the addition; 5. When updating, gitfetch first and repeat the merging and steps to submit the update. This method keeps the external project history complete and easy to maintain.

To force delete an unmerged Git branch, use the gitbranch-D command. This command ignores the merge status of the branch and deletes it directly. It is suitable for useless branches after testing, abandoned feature branches, or local old branches that need to be recreated from remotely. However, it should be noted that the submission record will still exist locally after deletion and will eventually be cleaned up by the garbage collection mechanism; after mistaken deletion, it can be restored through gitreflog, but the window period is short. Therefore, before execution, be sure to confirm that the branch is useless, uncooperated and the name is correct to avoid data loss.

Yes, you can use a command to create and switch to a new Git branch, the specific method is as follows: 1. Use gitswitch-c: This is a more modern and clear way, for example, gitswitch-cnew-feature will create and switch to a branch named new-feature immediately; 2. Use gitcheckout-b: This is an older but commonly used method, for example, gitcheckout-bnew-feature has the same effect as the former. Note: gitswitch was introduced in Git2.23, and old versions need to use gitcheckout. You can specify the branch based on other branches, such as gitswitch-cnew-
