Hi,
Via google I came across the define named
config-top.h:/* #define SYSLOG_HISTORY */
Changing it (manually) to
config-top.h:#define SYSLOG_HISTORY
Adds syslog statements such as:
Aug 9 16:52:55 x064 user:info syslog: HISTORY: PID=262242 UID=0 ls -ltr
Request #1
Add a ./configure variable, e.g., --with-syslog_history
I will think about this, but I am inclined not to do it. It's easy enough
to enable for those few user who want to do so.
Basically, I had not noticed it was there. It was only because I was at
a customer who said they had customized their version years ago that I
started searching for information about "bash and syslog".
Most of those hits were about using "fc" to add commands via the
external syslogger - and these are the oldest, so the first, read top
hits, that I got back. One of the replies mentioned the "top" include file.
This is actually, for me, the first compelling reason to switch shells
for "what is provided" to what I must be certain is added.
In short, having it included in ./configure simply give it much more
visibility - and perhaps adoption.
Request #2
At the request of a bash user on AIX I made the following change to make
the syslog output "standardized" to AIX format for many applications so
that the output looks like this:
Aug 9 17:30:12 x064 user:info syslog: bash[454682]: UID=0: ls -ltr
The better way to do this is to use openlog(). I will add the necessary
pieces to call openlog with the shell name as the identifier and LOG_PID
as the default value for the log options.
I try to make minimal changes. There are perhaps many other 'things' to
think about here. e.g., I thought about the syslog facility and level as
a configureable, but have decided against - as someone could divert the
log to an unmonitored facility - defeats the purpose.
However, maybe being able to specify what gets logged via a define
(order of arguments, length, etc) might be "nice".
But, openlog() - I'll readup, but I expect that may be what "AIX"
applications are using already to get "that" layout.
Many thanks for your consideration!
Chet
