>Description:
please add pipe-buffer switcher (On\Off) in /usr/sbin/praudit
for normal(realtime without data buffering) work follow shell constructions:

# praudit -l /dev/auditpipe | tee file.log
# praudit -l /dev/auditpipe > file.log
# ...
# praudit -l /dev/auditpipe | grep "xxxx"

or
# praudit -l /dev/auditpipe | grep "xxxx"

'praudit' using pipe-buffer (4096 bytes) for forward data
after full load pipe-buffer, data forward to out
pipe-buffer prevent realtime data forwarding
