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

wrap-and-sort
WRAP-AND-SORT(1) General Commands Manual WRAP-AND-SORT(1)
NAME
wrap-and-sort - wrap long lines and sort items in Debian packaging files
SYNOPSIS
wrap-and-sort [options]
DESCRIPTION
wrap-and-sort wraps the package lists in Debian control files. By default the lists will only split into multiple lines if the entries are
longer than 80 characters. wrap-and-sort sorts the package lists in Debian control files and all .install files. Beside that wrap-and-sort
removes trailing spaces in these files.
This script should be run in the root of a Debian package tree. It searches for control, control.in, copyright, copyright.in, install, and
*.install in the debian directory.
OPTIONS
-h, --help
Show this help message and exit.
-a, --wrap-always
Wrap all package lists in the Debian control file even if the entries are shorter than 80 characters and could fit in one line line.
-s, --short-indent
Only indent wrapped lines by one space (default is in-line with the field name).
-b, --sort-binary-packages
Sort binary package paragraphs by name.
-k, --keep-first
When sorting binary package paragraphs, leave the first one at the top. Unqualified debhelper(7) configuration files are applied to
the first package.
-n, --no-cleanup
Do not remove trailing whitespaces.
-d path, --debian-directory=path
Location of the debian directory (default: ./debian).
-f file, --file=file
Wrap and sort only the specified file. You can specify this parameter multiple times. All supported files will be processed if no
files are specified.
-v, --verbose
Print all files that are touched.
