Re: Delete Old Directories

[williams554]

Hello, this is what I would do. Please see comments

#!/usr/bin/perl
use strict; 

my $older_than = 45;

# my @dirs = #could be this depending then just foreach them

my @files = </Users/somedir/*>;

foreach my $filename (@files) {
    next unless (-d $filename); # this is only letting dirs get past
    if ( int( -M $filename) > $older_than) {
        #do something
        print"dir is old:$filename\n";#print what is deleted here.
        # test what you are going to delete 
        #&erase_directory ($filename); # after test uncomment this
        #rmdir $filename; # after test uncommnet this

    }
}

sub erase_directory {
    my $directory = shift @_;
    my @files = <$directory/*>;
    foreach (@files){
        unlink "$_";
    }
}

good luck, Rob

I'm trying with something like the code below, but I am not sure on line 31  if($file <= $exp_dir_date){... because if it create directories like: 20111020 20110901 20110920, it will not delete the 20111001. Is there a better way to accomplish this?
Here is the code I am talking about:

#!/usr/bin/perl -w

use strict;
use POSIX qw(strftime);
use Date::Calc qw( Today Add_Delta_Days);


# get todays date:::
my $file_date = sprintf "%04d%02d%02d", Today();

my $current_dir = "alldir";

my $exp_dir_date = sprintf "%04d%02d%02d",Add_Delta_Days( Today(), -45
+ );

my $dir_name = strftime("%Y%m%d",localtime(time));

# when this runs, it will create a new dir in alldir directory.

unless(-e $current_dir."/".$dir_name or mkdir ($current_dir."/".$dir_n
+ame, 0755)) {
        die "Unable to create $current_dir."/".$dir_name\n";
    }

print "\n**\n";

#now open $current_dir and read its content deleting any directory old
+er than 45 days

opendir (DIR, $current_dir) or die "Couldn't open directory, $!";
while (my $file = readdir DIR)
{
  next if $file=~/^\./;
  if($file <= $exp_dir_date){
    
    print "\nDELETE:::$file - $file_date - $exp_dir_date\n\n";
    rmdir("alldir/$file"); #-------> remove directory 
  }else{
    
    print "\nOK:::$file* = $file_date - $exp_dir_date\n\n";      
  
  }
}
closedir DIR;

print "\n\ndone\n";

Give this a try

#!/usr/bin/perl
use strict;
use POSIX qw(strftime);
use Date::Calc qw( Today Add_Delta_Days);

my $older_than = 45;


# get todays date:::
my $file_date = sprintf "%04d%02d%02d", Today();

my $current_dir = "alldir";

my $exp_dir_date = sprintf "%04d%02d%02d",Add_Delta_Days( Today(), -45
+ );

my $dir_name = strftime("%Y%m%d",localtime(time));

# when this runs, it will create a new dir in alldir directory.

unless(-e $current_dir."/".$dir_name or mkdir ($current_dir."/".$dir_n
+ame, 0755)) {
        die "Unable to create $current_dir."/".$dir_name\n";
    }

print "\n**\n";

#now open $current_dir and read its content deleting any directory old
+er than 45 days

my @files = </$current_dir/*>;

foreach my $filename (@files) {
    next unless (-d $filename); # this is only letting dirs get past
    if ( int( -M $filename) > $older_than) {
        print"dir is old:$filename\n";#print what is deleted here.
        # test what you are going to delete 
        #&erase_directory ($filename); # after test uncomment this
        #rmdir $filename; # after test uncommnet this

    }
}

sub erase_directory {
    my $directory = shift @_;
    my @files = <$directory/*>;
    foreach (@files){
        unlink "$_";
    }
}

Good luck, Rob
