Start a temporary webserver using python SimpleHTTPServer

To start a HTTP server on port 8000 (which is the default port), simple type:

python -m SimpleHTTPServer

The PWD(present working directory) by which the command is executed will be served via HTTP. If we want to use custom port, use

 

python -m SimpleHTTPServer <portnumber>

For eg python -m SimpleHTTPServer 8080

 

 

Remove a commit from local and remote history

  • git reset –soft commit_id
  • git stash save “message”
  • git reset –hard commit_id
  • git stash apply stash [email protected]{0}
  • git push —force

Renaming git branch

1. Rename your local branch.
If you are on the branch you want to rename:
git branch -m new-name
2. Delete the old-name remote branch and push the new-name local branch.
git push origin :old-name new-name
3. Reset the upstream branch for the new-name local branch. Switch to the branch and then:
git push origin -u new-name

Delete a git commit that is already pushed

git log
 to check the commit list.
For example, commit 7f6d03 was before the 2 wrongful commits and we want to restore to that commit .
Force push that commit as the new master:
git push origin +7f6d03:master
The + is interpreted as forced push.
Another way
You can also use git reset to undo things. Then force push.
git reset 7f6d03 –hard
git push origin -f
