Split the file with renaming.
Hi Team,.

I am writing a script find the files which is not .gz format, split it into files which are 50000 line entries per file(using split -l 50000) then compress the smaller files using gzip and delete the original/big file.

After splitting it is creating the files in its own naming format where as I want to keep the same name with .seg1, .seg2, .seg3 so on.

I am not getting a hint to get the same naming with .seg*

could you help.

sa2

sa2(8)							    BSD System Manager's Manual 						    sa2(8)

NAME

     sa2 -- Generate a system activity daily report file.

SYNOPSIS

     /usr/lib/sa/sa2 [-dgpu] [-n mode] [-e time] [-f filename] [-i seconds] [-s time]

DESCRIPTION

     The sa2 command is a shell script used to invoke the system activity reporter sar for purposes of generating the standard default daily
     report file.  The report file generated is, /var/log/sa/sardd where the dd represents the current day of the month.  The sa2 options are the
     same as those documented in sar(1).

     When sa2 runs, it will also remove data and report files, found in /var/log/sa, that are more than one week old.

     The sa2 command is intended to be started by cron.

EXAMPLE CRON ENTRY

     # Starting at 8am collect system activity records
     # every 20 minutes for 12 hours
     # 20 minutes = 1200 seconds
     # 12 hours with 3 samples each hour = 36 loops

     0 8 * * 1-5 /usr/lib/sa/sa1 1200 36

     # After the 12 hour period,
     # collect a system activity report

     30 20 * * 1-5 /usr/lib/sa/sa2 -A

FILES

     /var/log/sa/sardd	Default daily report file.
     /var/log/sa/sadd	Default daily data file.

			dd are digits that represent the day of the month.
