Stashing Files
git stash temporarily saves changes we have made to our files so that we can work on something else, and then come back and unstash those changes.
How is stashing useful?
let’s say we have two branches and we are working on branch A, now when we switch to branch B, all the uncommitted files (staged / unstaged) will either get copied to branch B or we’ll get an error. To resolve this issue we can either first commit to branch A or we can stash those files and then move to branch B. The stashed files will not effect branch B, and can be restored when we move back to branch A.
Stashing Files
git stash
When we run git stash, all the staged files will go to stash area. By default, unstaged files will not be stashed. Adding the -u option (or --include-untracked) tells git stash to also stash your untracked files
Restoring Stash
git stash pop
This will restore the last changes added to stash
