Top Forums Shell Programming and Scripting Help with Shell Scrip in Masking particular columns in .csv file or .txt file using shell script Post 302985155 by Don Cragun on Sunday 6th of November 2016 11:59:44 PM
You have a script. (It is grossly inefficient, throws away all diagnostic output, and never checks for errors; so you and we have no idea where something is going wrong if something is going wrong.) You have not said what it is doing wrong. You have not shown us sample CSV files from your database extractions. You have not shown us the output you are getting from your script. And, you have not shown us the output you are hoping to get from your script.

I would guess that instead of invoking awk once for each field to be updated in each file to be updated, you could just invoke awk once to update all of the fields in all of the files. And, this would make your script run much faster. But, without samples and a clear statement of what you are trying to change in your existing script; we don't know what needs to be done.

Please help us help you!

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME
Test::Script - Basic cross-platform tests for scripts DESCRIPTION
The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS
script_compiles script_compiles( 'script/foo.pl', 'Main script compiles' ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. script_runs script_runs( 'script/foo.pl', 'Main script runs' ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. SUPPORT
