There most likely should be for loop. While I ask these questions and try to come up with solutions for easier processing on these logs, I'm taking small tutorials on the different commands (awk, sed, unique, cut, sort). Obviously these things will give me statistics that would take extremely long to manually perform, considering the amount of data that's present. So, in short, I believe it's a loop I'm looking for. =}

The directory contains roughly 50 files. The amount of files will continue to grow, 1 per day. So the idea is to incorporate, into the script, something that will search the NEW files and append to the current, existing file.

Then after that is smoothly running on a cron job, I will look into making a script that will give me stats on particular fields (I'm assuming, using the awk, cut, unique, and sed commands).

Scrutinizer, feel free to point me in a general direction to get started, instead of spelling everything out. It does seem that the examples you've listed in this thread are at an expert level of scripting. Where many tutorials I've been through seem to make separate lines for each (command?) and have a debug included incase something with the files change or it simply just doesn't work someday.

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME
getusershell, setusershell, endusershell - get legal user shells SYNOPSIS
#include <unistd.h> char *getusershell(void); void setusershell(void); void endusershell(void); DESCRIPTION
The getusershell() function returns a pointer to a legal user shell as defined by the system manager in the file /etc/shells. If /etc/shells does not exist, the following locations of the standard system shells are used in its place: /bin/bash /bin/csh /bin/jsh /bin/ksh /bin/ksh93 /bin/pfcsh /bin/pfksh /bin/pfsh /bin/sh /bin/tcsh /bin/zsh /sbin/jsh /sbin/pfsh /sbin/sh /usr/bin/bash /usr/bin/csh /usr/bin/jsh /usr/bin/ksh /usr/bin/ksh93 /usr/bin/pfcsh /usr/bin/pfksh /usr/bin/pfsh /usr/bin/sh /usr/bin/tcsh /usr/bin/zsh /usr/sfw/bin/zsh /usr/xpg4/bin/sh The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells. The setusershell() function rewinds the file or the list. The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells. RETURN VALUES
The getusershell() function returns a null pointer on EOF. BUGS
All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved. NOTES
Restricted shells should not be listed in /etc/shells. SunOS 5.11 1 Nov 2007 getusershell(3C)
