I have git project checked out at ~/llvm. Inside of there, inside of a “tools” directory, I have another project checked out as “lldb”:
~/llvm/tools/lldb
I wrote an alias which would help me update all my projects:
all = !find . -type d -name .git | sed 's:/.git::' | xargs -I{} -t git -C {} $1 && :
This would allow me to be inside of ~/llvm and type "git all pull" and get all my projects updated.
It seems that at some point this broke. If try to use this alias under git 2.6.4, it only updates the llvm project.
The interesting thing is that if I pass fetch, instead of pull: "git all fetch", then it seems to work correctly.
Here’s the GIT_TRACE output for “git all pull” when in ~/llvm:
