Hi all,

I'm writing a URI handler for git that uses bash/zenity to allow the user to clone a git repository when a git:// link is clicked in a browser.

I'm having a bit of trouble getting git's output into zenity, however. git outputs its progress messages (everything except the "Initializing" message) on stderr, which shouldn't be a problem. Something weird has happened though; the moment I try to pipe git's stderr to stdout or a file, it disappears.

A simple way to test this:

git clone git://your.favourite/git/repo 2> file1 git clone git://your.favourite/git/repo 2>&1 > file2

file1 will be empty (why?) and file2 will contain only the "Initializing" message, which came from stdout.

TL;DR why can't I pipe git's stderr output?

Help would be greatly appreciated; thanks in advance.

git-clone(1):

       --progress
           Progress status is reported on the standard error stream by default
           when it is attached to a terminal, unless -q is specified. This
           flag forces progress status even if the standard error stream is
           not directed to a terminal.

Andreas.
