Standardization of input source data files using shell script
Hi there,

I'm a newbie in unix and am fishing for options related to how raw input data files are handled. The scenario, as I'm sure y'all must be very familiar with, is this : we receive upwards of 50 data files in ASCII format from various source systems - now each file has its own structure (columns, datatypes etc) as well as certain "impurities" e.g. leading/trailing whitespaces, junk characters (produced during conversion from mainframe data to ASCII) etc...there is a need to 'sanitize' these files i.e. strip them of whitespaces, junk characters etc - how do we do this.....

Ideally, we would like to have a common shell script that parses each input file and produces a clean version (is this possible? will I need to have multiple shell scripts , one for each file?)

Can you please provide feedback based on your experience...

Thanks

sysstat

SYSSTAT(5)							Linux User's Manual							SYSSTAT(5)

NAME

       sysstat - sysstat configuration file.

DESCRIPTION

       This  file is read by sa1(8) and sa2(8) shell scripts from the sysstat's set of tools.  It consists of a sequence of shell variable assign-
       ments used to configure sysstat logging.  The variables and their meanings are:

       HISTORY
	      The number of days during which a daily data file or a report should be kept. Data files or reports older than this number  of  days
	      will be removed by the sa2(8) shell script.

       COMPRESSAFTER
	      Number of days after which daily data files are to be compressed, either by gzip or bzip2.

       SADC_OPTIONS
	      Options  that  should be passed to sadc(8).  With these options (see sadc(8) manual page), you can select some additional data which
	      are going to be saved in daily data files.  These options are used only when a new data file is created. They will be  ignored  with
	      an already existing one.

FILES

       /etc/sysstat/sysstat
