useful commands for day 2

Inspecting history

• git grep sometext

• git annotate somefile --- git annotate R/session.R | grep "No links matched that expression"

git grep "No links matched that expression" git annotate R/session.R (find has for the sentence 'no links matched that expression')

aboved two commands can be replaced by :

git annotate R/session.R | grep "No links matched that expression"

• git checkout -b branchname somehash create new branch which is named branchname with somehash and switch to it. when you want to delete branchname, you need to

git checkout -b meusum abc123
git checkout master
git branch -d museum

finding out when something broken git bisect

git bisect start
git bisect good f0ea950  # this is a commit that worked
git bisect bad master    # last commit is broken
python get_pi.py      # now compile and/or run
  # after that decide whether
git bisect good
  # or
git bisect bad
python get_pi.py     # now compile and/or run 
  # after that decide whether
git bisect good
  # or
git bisect bad
  # iterate until commit is found

repeat aboved process until :

Bisecting: 0 revisions left to test after this (roughly 0 steps)

git log --oneline | tail -n 1

finding the first commit

generate ssh key

ssh-keygen -t rsa -C "[email protected]"

id_rsa (私钥)

id_rsa.pub (公钥)
