Re: assigning printf statement to
an array(Document link: Derek
Bellner Smith)
my @a=
map {$hdir.$_->[1]} # select filename
grep {$_->[0] > 100} # exclude age <= 100
map { [
sprintf ("%.0f",( $now - ( stat("${hdir}$_" ) )[9] ) / ONE_DAY ),
$_
] } # create aref [age, filename]
grep {$_ ne "." and $_ ne ".."} # exclude unwanted
sort readdir DH; # get all files
The map-grep-map-construct is quite common for problems like yours
("But I cannot use $_ b/c $_ is the dir name.").
This is working but it not printing the calculation "days old" for each
filename??? I want to print the aref.
I verified that it is indeed only printing those files over 100 days old,
but I need output such as,
ABDELFATTAH__FAITH_M702515438: 101
as opposed to
ABDELFATTAH__FAITH_M702515438
I will also follow up with a line by line question of the code.
thanks again!

instead of the foreach loop you could use a single statement [untested]:
(read from bottom to top)
my @a=
map {$hdir.$_->[1]} # select filename
grep {$_->[0] > 100} # exclude age <= 100
map { [
sprintf ("%.0f",( $now - ( stat("${hdir}$_" ) )[9] ) / ONE_DAY ),
$_
] } # create aref [age, filename]
grep {$_ ne "." and $_ ne ".."} # exclude unwanted
sort readdir DH; # get all files
The map-grep-map-construct is quite common for problems like yours
("But I cannot use $_ b/c $_ is the dir name.").
