Re^3: extract the value before a particualr string

$1 holds the result of the pattern match captured inside (parenthesis). If you had multiple parens then there would also be a $2, $3, etc. The $/ variable is the input record separator, this defaults to being a newline, so print $_,$/ is equivalent to print "$_\n". The $ after total tells the regex engine that total will be the last thing on the line.

So, if we need to do the operation on a variable line and assign the output to a variable how do we go abt it??? `$count = $line if/\s+?(\d+?)\/total$/;` [download] will this look fine?	[reply] [d/l]

No, that would be `$count = $1 if $line =~ /\s+?(\d+?)\/total$/;` [download]	[reply] [d/l]
