Perl script to create csv files with a pattern – Generic script.

I was having a really bad day and needed a quick solution to create some csv files. And this I needed to do for multiple data kinds and patterns, so I created this small script to do the job for me…

#Number of rows required in the output.

$rows = 100;

#The config and the output file

open (CF_FILE, \”<Config.test\”);
open (OUT_FILE, \”>test.csv\”);

# No need to change anything below this.

$count = 0 ;

#read a line from config file of the type

#also any line starting with # is treated as comment.

# startingvalue incrementvalue

# so you can have any number of fields here and all of them you would be joined with , to write to the output file.
while (<CF_FILE>)
/^#/ && next;
@vars = split(/ /);
$arr[$count] = $vars[0];
$arr_inc[$count] = $vars[1];
for ($i=0; $i < $rows; $i++)
$line = join (\”,\”,@arr);
print OUT_FILE \”$line\\n\”;
for ($j=0; $j < $count; $j++)
$arr[$j] += $arr_inc[$j];
