# Goes through all git repositories in the current directory
|
|
# and runs "git prune" and "git gc --aggressive" to pack
|
|
# objects very efficiently and reduce size sometimes dramatically
|
|
#
|
|
# Works by finding the repositories which have a gc.log
|
|
# file, indicating that git garbage collection failed at some
|
|
# point, causing the repository to grow very fast
|
|
# each time new objects are fetched.
|
|

|
|
# Example: llvm-project: divided disk usage by 60!
