Solaris 11

So i have been asked to write a script for a friend who has a server running solaris 11. My problem is the correct syntax i can't seem to get it work with the follow code, i have read through the date man page and found no work around

Code:

#!/bin/sh
rsync -avz /mnt/backups/`date --date=yesterday +\%Y-\%m-\%d`-`date --date=yesterday +\%A`/server1/ /mnt/backups/`date +\%Y-\%m-\%d`-`date +\%A`/server1/

This is the script i wrote to cleanup each day

Code:

#!/bin/sh
# Definitions
sixdaysago=$(date --date='5 days ago' +%Y-%m-%d-%A)
# Delete backups from 5 days ago
rm -rf /mnt/backups/$sixdaysago

Any one able to help me or a should i take a different approach in how i cycle through my backups ?

Hi there,

I haven't come accross support for the --date option on any platform other than Linux.

As a possible solution I can offer a small hack of a perl script I used for this once.

Code:

#!/usr/bin/env perl
use strict;
my @days = qw/Sunday Monday Tuesday Wednesday Thursday Friday Saturday/;
my $utime = time();

if ($#ARGV == 0) {
        my $days_to_add = $ARGV[0];
        $utime += 86400 * $days_to_add;
}

my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime($utime);
$year += 1900;
$mon++;
$yday++;
printf "%04d-%02d-%02d-%s\n",$year,$mon,$mday,$days[$wday];
exit(0);

Save this to a file, make it executable, and run it with an optional number_of_days_to_add_or_subtract argument.

I hope this helps!

This should just work on Solaris 11:

Code:

sixdaysago=$(/usr/gnu/bin/date --date='5 days ago' +%Y-%m-%d-%A)

Thanks for that will test the code tomorrow, The main problem is the code to reduce the network transfer by syncing yesterdays files first then syncing only those that have been updated. Any idea how i could adjust the follow to work as currently i get the illegal operator error for the "--date=yesterday"

Code:

`date --date=yesterday +\%Y-\%m-\%d`-`date --date=yesterday +\%A`

Code:

rsync -avz /mnt/backups/`date --date=yesterday +\%Y-\%m-\%d`-`date --date=yesterday +\%A`/server1/ /mnt/backups/`date +\%Y-\%m-\%d`-`date +\%A`/server1/

That would be:

Code:

$(/usr/gnu/bin/date --date=yesterday +\%Y-\%m-\%d)-$(/usr/gnu/bin/date --date=yesterday +\%A)
