Should I write a PERL Script or Shell Script?
Hello,
I have done some BASIC shell scripting/PERL scripting before so I am familiar with the languages. I am not really sure which one would lend itself better to the application I have to write.
I am required to scan the message logs for possible break in attempts. If I use shell scripting I could use GREP for a particular pattern and I am sure PERL has some similar pattern scanning capability. I am not sure which language could accomplish the following more easily: In each warning attempt I would have to locate the username used to loggin and keep track of how often this username attempted a loggon in a variable.
Opinions/suggestions?

openipmish
openipmish(1) Shell interface to an IPMI system openipmish(1)
NAME
openipmish - Shell interface to an IPMI system
SYNOPSIS
openipmish [option]
DESCRIPTION
The openipmish is a command interpreter that gives the full power of the OpenIPMI library to a user-level command language. It is designed
so it can easily be driven with a scripting language like TCL, it has well-formed output.
openipmish starts up with no connections or anything of that nature. You must enter commands to make connections to domains.
OPTIONS
--dmsg Turn on message debugging, this will dump all messages to debug log output.
--drawmsg
Turn on raw message debugging, this will dump all low-level messages to debug log output. This differes from normal message debug-
ging in that all protocol messages are also dumped, not just IPMI messages.
--dmem Turn on memory debugging, this will cause memory allocation and deallocations to be checked. When the program terminates, it will
dump all memory that was not properly freed (leaked).
--dlock
Turn on lock debugging, this will check lock operations to make sure that locks are help in all the proper places and make sure that
locks are properly nested.
--snmp Enable the SNMP trap handler. openipmish must be compiled with SNMP code enabled for this option to be available.
--help Help output
COMMANDS
openipmish follows the standard command syntax defined in ipmi_cmdlang(7). See that for the details on most commands. The IPMI manual
that comes with OpenIPMI will also be quite handy.
openipmish defines some commands that are not in the standard command language. These are:
read Read and execute commands from the given file.
exit Quit
redisp_cmd on|off
Normally, openipmish redisplays the command line when an event comes in. This is nice for interactive use, but bad for scripting.
This lets you turn that function on and off.

ipmi_cmdlang(7), ipmi_ui(1)
