Question

I want to generate a bundle with git but for some important reason I need it on the standard output not in a file.
Is there a alternate command at git bundle to do this ?

Answer 1

Use - as the file argument to git bundle:

$ git bundle create - HEAD~10.. > outfile    
Counting objects: 83, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (67/67), done.
Writing objects: 100% (68/68), 8.42 KiB, done.
Total 68 (delta 55), reused 0 (delta 0)
$ file outfile
outfile: Git bundle
$ ls -l outfile
-rw-r--r-- 1 author author 8789 2012-09-21 15:20 outfile

Note: as of git 2.17.0, the above commands works correctly only when invoked at the root directory of the working tree. (In other directories, a - file is created and outfile ends up empty.)
