do
sleep 5
echo "${n}:Fluent is running...."
n=${n}+1
done
I have the following doubts:
1) In the first line - I am aware that we are defining a variable n and setting its value to zero. What does the '-i' do ?
2) Does the while loop say that while vel.txt does NOT exist, keep printing "Fluent is running..." ? What does the '-s' stand for?
3) I need to convert this to DOS batch script..
Is the following, a correct translation ?
I have not done DOS for 15 years. It looks reasonable except
for the {} around the n. I do not remember that.
SET n=0
WHILE NOT vel.txt
DO
SLEEP 5
ECHO "%{n}% : Fluent is running..."
n = %{n}% + 1
DONE
Any help will be much appreciated.
Thanks

test::script
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.
