I have been using git stash to quickly discard all my changes on my local machine. At first I thought nothing of it but then I became concerned that it might start to fill up my hard drive on my machine, especially if I am stashing a lot of changes in many files.
Do stashes take up a lot of hard drive space on my local machine? Do I need to delete my git stash regularly?
If you're just stashing changes to your source code, it will take a loooooooong time before you'll even notice the storage space the stash takes up. However, this is wasteful, and if you over do it, may cause a performance degradation to your git project, so clearing it is probably the right thing to do.
To quickly discard unwanted changes you could always use git reset HEAD --hard.
