Basic IF Command Question
Hi,
I have a months worth of data that I need to separate into weekly files. There is a date column with dates in the following format: YYYYMMDD.
I'm thinking I can create the weekly files by using a grep command combined with an IF command and specify each day of the specific week I'm extracting within the if command. Does this seem efficient? How would I set up the IF command?

uname -i gives machine id and uname -a is more comprehensive way to look.

month including an overview.
Typical crontab used to invoke this are

# Weekly report on the percent availability of network systems with no detail
0 8 * * * /usr/local/smokeping/bin/tSmoke.pl --q --to=mailbox@company.com.invalid --weekly --detail=0
SETUP
When installing tSmoke, some variables must be adjusted to fit your local system.
We need to use the following libraries:
Smokeping
RRDTool Perl bindings
Getopt::Long
Set up your libraries:
use lib "/usr/local/smokeping/lib";
use lib "/usr/local/rrdtool-1.0.39/lib/perl";
Point to your Smokeping config file
my $cfgfile = "/usr/local/smokeping/etc/config";
Modify the Smokeping config file to include a path for tmail in the General section:
tmail = /usr/local/smokeping/etc/tmail
