git

## checkout to all branches in remote
```
#!/bin/bash

#Whenever you clone a repo, you do not clone all of its branches by default.
#If you wish to do so, use the following script:

for branch in `git branch -a | grep remotes | grep -v HEAD | grep -v main `; do
   git branch --track ${branch#remotes/origin/} $branch
done
```

## sign commit
```
$ cat ~/.gitconfig                                                                                                                              [16:12:30]
