THis is quick and dirty and just assumes that your data is structured the way you did in your post.
#!/usr/bin/perl
open IN, "in.txt"
or die "Can't Open input\n";
$count = 0;
while (<IN>)
{
chomp($_);
if ($_ =~ /Users/)
{
print $_,"\t=\t";
}
elsif ($_ =~ /\.\.\./)
{
print $count,"\n";
$count = 0;
}
else
{
if ($_)
{
$count++;
}
}
}
gives this as a result from your example data
Users of some feature = 3
Users of some other feature = 3
Users of yet another feature = 0
