Hi,
I'm trying to pipe my Apache 2.0.54 logs to a script, but never seem
to get any logs sent through the pipe.

Apache starts my script (actually a python program) which runs fine
until it tries to read a log from stdin.  At that point the script
hangs and never gets any input.

My script works correctly for other sources, ie: "cat access.log |
script.py" works correctly.

Also, I tried just piping apache logs to cat, ie:

CustomLog "|/bin/cat >> /var/log/apache2/test.log" common

I get this is my error.log:

piped log program ' /bin/cat >> /var/log/apache2/test.log' failed unexpectedly
/bin/cat: >>: No such file or directory

The piped log program must be an executable command with possible
arguments, not something that you would pass to the shell.  So if you
made a shell script containing
#!/bin/sh
/bin/cat >> /bar/log/apache2/test.log

and then used the shell script as the target, you would have more luck.

Have you tried the python equivalent of a trivial program that simply
pipes the log entries to a file?  What does it look like?
