tmtowtdi, but if I knew that I was going to have a number with no
punctuation after the text "ETRACK_TOTAL_RECS : " that I wanted to capture,
I'd do:
$total_count =~ /ETRACK_TOTAL_RECS\s*:\s*(\d+)/;
Then the number would be in $1.
If I wasn't sure of the format (i.e., it could have a decimal, commas, etc),
but knew that I wanted to capture everything from the : to the end of the
string, I'd do:
$total_count =~ /ETRACK_TOTAL_RECS\s*:\s*(.+)/;
And the result would be in $1.
Hope this helps,
