MacOS - Find all video, audio, CSVs, text files and copy it to other directories for backup etc

You don’t need to go to Finder, lookout for each & then copy paste.

You can either copy all of them at once using below find command with regex incorporating with `rsync` or `cp` -

Using rsync -

find -E . -regex '.*\.(jpg|png|mp4|mp3|csv|txt)' -exec rsync -avzh {} ~/found/ \;
Using cp -

mkdir ~/found

find -E . -regex '.*\.(jpg|png|mp4|mp3|csv|txt)' -exec cp {} ~/found/ \;

You can also copy them to individual directories -

Copy all MP4 files to `videos` directory -

Using rsync -

find -E . -regex '.*\.(mp4)' -exec rsync -avzh {} ~/found/videos/ \;
Using cp -

mkdir ~/found

find -E . -regex '.*\.(mp4)' -exec cp {} ~/found/videos/ \;

Copy all image files to `images` directory -

Using rsync -

find -E . -regex '.*\.(jpg|png|jpeg)' -exec rsync -avzh {} ~/found/images/ \;
Using cp -

mkdir ~/found

find -E . -regex '.*\.(jpg|png|jpeg)' -exec cp {} ~/found/images/ \;

Note: We can create simple shell script and put it as a cronjob, using rsync you can perform inremental backup of your data to another drive or folder.

Terraform is Terrafic!

You are gonna love it too. Have covered below in “basics-lesson1” -

➛ Create VPC with 3 public & private subnets span across 3 AZs with internet & NAT Gateway.
➛ Create IAM policies, roles & instance profiles.
➛ Create Autoscaling groups, Launch templates & SSH Key pairs for Application & Bastion host.
➛ Create Target group & Application load balancer.
➛ Create security groups for Application, ALB, Bastion & Database instance.

Just a single command and you create all of the above in no time. Terraform core takes care of all the inter-dependencies, I love this functionality.

Here you go, straight into the action -

Life - Profit & Loss

Fri, 09 Mar 2018 00:00:00 +0000

FAILURES ARE IMPORTANT

There is nothing in life which comes with just profit or just loss, it always has a combination of both. At times when we fail, we got to take it as experience. Obviuosly, we are humans & cannot commit everything right everytime without failures.
