Updating VirtualBox boxes using bash script
Forgot where i got this script to update Virtualboxes. Worth sharing though
#!/bin/bash
# Find all boxes which have updates
AVAILABLE_UPDATES=`vagrant box outdated --global | grep outdated | tr -d "*'" | cut -d ' ' -f 2`
if [ ! ${#AVAILABLE_UPDATES[@]} -eq 0 ]; then
for box in $AVAILABLE_UPDATES ; do
echo "Found an update for $box"
# Find all current versions
VERSIONS=`vagrant box list | grep $box | cut -d ',' -f 2 | tr -d ' )'`
# Add latest version
vagrant box add --clean $box
BOX_UPDATED="TRUE"
# Remove all old versions
for version in $VERSIONS ; do
vagrant box remove $box -f --box-version=$version
done
done
echo "All boxes are now up to date!"
else
echo "All boxes are already up to date!"
fi
vagrant box outdated --global
Sample run:
╭─cperez@mctoffer-2.local ~

Bridged wifi Vmware fusion in MacOs Monterey

Replace a file in Puppet only if the file exists
Replace file in Puppet only if the file exists. So i have this question from my colleague. It sounds simple right? but it is not.
Some says that use exec with onlyif but it produces warning/errors logs if the file doesn't exist. In which functionality, it will suffice your needs, but you will have this warning logs.
This is the workaround that i've done:
file { '/tmp/file01.txt': source => "puppet:///modules/common/custommodule/file01.txt", owner => 'root', group => 'root', mode => '0640', }
exec {"copy_file01": command => "/usr/bin/diff /tmp/file01.txt /var/tmp/file01.txt; if [ $? -ne 0 ]; then /bin/cp /tmp/file01.txt /var/tmp/file01.txt; fi", require=> File['/tmp/file01.txt'], onlyif => "/usr/bin/test -e /var/tmp/file01.txt",
}

OnePlus One
Matagal na akong IOS device user. Nagsimula sa Apple Iphone 4 then Iphone5. Although, my first smartphone device was a Sony Ericsson Xperia X10 android phone.
Siguro masyado lang ako na-bored sa user interface ng IOS kaya bumalik ulit ako sa Android. Matagal ko din pinagisipan kung Google Nexus 6 or OnePlus One... Nexus6 have superb up-to-date specs... but price-wise, I got OnePlus One. Since in my opinion(yung may mga budget), max lifespan lang ng isang phone ay 2 years.... magpapalit ka na agad(again, if you have the budget)
How to get the last IP address on the Subnet using Ruby
>> require 'ipaddr'
>> ip=IPAddr.new("192.168.1.0/24")
=> #<IPAddr: IPv4:192.168.1.0/255.255.255.0>
>> gateway=IPAddr.new(ip.to_range.last.to_i-1,ip.family).to_s
=> "192.168.1.254"
>> ip=IPAddr.new("192.168.1.0/20")
=> #<IPAddr: IPv4:192.168.0.0/255.255.240.0>
>> gateway=IPAddr.new(ip.to_range.last.to_i-1,ip.family).to_s
=> "192.168.15.254"
to get the first ip of the subnet
>> gateway=IPAddr.new(ip.to_range.first.to_i+1,ip.family).to_s

Apology Accepted!!!
Vmware apologizes for technical difficulties on the recent webcast Technology Day Online. It looks like the webcast provider was caught off guard on the situation. To compensate, VMware will be sending me a USB memory stick containing all of the materials presented on the said event.
Well.. apology accepted!!!!! :)
Our Samsung LCD TV retired
Our Samsung LCD TV retired after exactly 3 yrs of service. Bad thing is that it is already out of warranty. Yesterday the screen suddenly turns to white that you can barely see the images.
sed Galore
Find and replace string recursively
find /home/penoycentral/whichfolder -type f -print0| xargs -0 sed -i 's/oldstring/newstring/g'
If you want to make sure that you are changing which, use the old grep first
find /home/penoycentral/whichfolder -type f -print0| xargs -0 grep -i oldstring
Example Problem: Change /etc/bind to /var/named/master in named.conf
Just print what will be changed
sed -n 's/\/etc\/bind/\/var\/named\/master/p' named.conf
to change:
sed -i 's/\/etc\/bind/\/var\/named\/masterr/g' named.conf
Change double qoute to single qoute
sed -i "s/[\"]/\'/g" some-file.pp
