git reset - unstage all files
git checkout . revert all changes
git checkout [some_dir|file.txt] revert only that file
-- safe way --
git stash -- verify you are in the state you want
git stash drop -- if ok just drop the stash
What is the meaning of ^M in 'git diff'?
^M represents carriage return. This diff means something removed a Unicode BOM from the beginning
of the line and added a CR at the end.
The ^ symbol stands for Control, so ^M means Ctrl+M.
To get from that to the actual ASCII character code, you take the base character and flip bit 6 (i.e. XOR with 64).
For letters, that just means subtract 64. So, for example, ^A is character code 1 (because A is 65).
^M is 77 - 64 = 13 (because M is 77), which corresponds to carriage return in ASCII.
Set windows style:
git config --global core.autocrlf truegit config --global core.eol crlf
Practical uses of git reset --soft?
# Move the HEAD, and just the HEAD, one commit back!
git reset --soft HEAD^
# Move the HEAD, and just the HEAD, two commits back!
git reset --soft HEAD^^

Update and clean when updating .gitignore
steps:
step1: add files or folders to gitignore
step2: remove the files from the git cache
git rm -r --cache "FolderName"
step3: comit the curren change
git commit -m "removed FolderName folder from git chache and updated the .gitignore file"
step4: push the chang
git push

Build.ArtifactStagingDirectory - The local path on the agent where any artifacts are copied to before being pushed to their destination. For example: c:\agent_work\1\a
Build.BinariesDirectory - The local path on the agent you can use as an output folder for compiled binaries. For example: c:\agent_work\1\b.
Build.Repository.LocalPath - The local path on the agent where your source code files are downloaded. For example: c:\agent_work\1\s. This variable is synonymous with Build.SourcesDirectory.
