If you want the field which is just after abc, do not look for numbers: `my ($after_abc) = $string =~ /abc\t([0-9]+)/;` [download]	[reply] [d/l]

If your data is homogeneous, you can use split, if you want, as alternative to regex (use undef to discard the values that are not interesting for you): `my (undef,undef,undef,$val,undef,undef)=split /\s/,"28504 0 abc 148782859 42 101M";` $val have the value that you need in this example	[reply] [d/l]

Or just the number you need: `my $var = (split /\s/,"28504 0 abc 148782859 42 101M")[3]`	[reply] [d/l]

Assuming the abc could be any non-numeric string, something like `/\D+\s+(\d+)/` should get what you want	[reply] [d/l]
