# Bisect
----------
## Bisect
- Find a commit that introduced a bug
- Works through a process of elimination
- Specify a known good and bad revision to begin
----------
## Bisect
1. Start the bisect process
2. Enter the bad revision (usually latest commit)
3. Enter a known good revision (commit/branch)
4. Run code to see if bug still exists
5. Tell bisect the result
6. Repeat the previous 2 items until you find the offending commit
----------
## Setup
```
mkdir bisect-ex
cd bisect-ex
touch index.html
git add -A
git commit -m "starting out"

# Add all good
git add -A
git commit -m "second commit"
vi index.html
# Add all good 2
git add -A
git commit -m "third commit"
vi index.html
```
----------
```
# Add all good 3
git add -A
git commit -m "fourth commit"
vi index.html
# This looks bad
git add -A
git commit -m "fifth commit"
vi index.html
# Really bad
git add -A
git commit -m "sixth commit"
vi index.html
# again just bad
git add -A
git commit -m "seventh commit"
```
