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?

Could someone tell me the command to find out the OS version which will give 12 character not the 9 characters(which is usually machine id).
uname -i gives machine id and uname -a is more comprehensive way to look.

weekly
WEEKLY(5) BSD File Formats Manual WEEKLY(5)
NAME
weekly, weekly.conf -- weekly maintenance
DESCRIPTION
The /etc/weekly script is run, by default, every Saturday morning on a NetBSD system. The /etc/weekly.conf file specifies which of the stan-
dard weekly services are performed.
The variables described below can be set to ``YES'' or ``NO'' in the /etc/weekly.conf file. The default settings are in the
/etc/defaults/weekly.conf file. (Note that you should never edit /etc/defaults/weekly.conf directly, as it is often replaced during system
upgrades.)
rebuild_locatedb This rebuilds the locate(1) database, /var/db/locate.database, which must also exist, in order to be rebuilt.
rebuild_mandb This rebuilds the apropos(1) database /var/db/man.db, using makemandb(8) with the -f option.
rebuild_whatisdb This rebuilds the whatis(1) database(s). Note that NetBSD provides a default whatis.db for the system manual pages and
this may not be needed. (Adjust your /etc/man.conf as necessary; see man.conf(5) for details.)
FILES
/etc/weekly weekly maintenance script
/etc/weekly.conf weekly maintenance configuration
/etc/weekly.local local site additions to /etc/weekly
SEE ALSO
daily.conf(5), monthly.conf(5)
HISTORY
The /etc/weekly script first appeared in 4.3BSD. The /etc/weekly.conf configuration file appeared in NetBSD 1.3.
