Copy S3 To Another Region

June 22, 2021

Buckets are regional. Your source and destination buckets should be in different regions.

aws s3 sync s3://DOC-EXAMPLE-BUCKET-SOURCE s3://DOC-EXAMPLE-BUCKET-TARGET

aws s3 sync s3://DOC-EXAMPLE-BUCKET-SOURCE s3://DOC-EXAMPLE-BUCKET-TARGET

Use the sync command. It will copy new or modified files.

Audacity Copy

August 8, 2020

I was getting an error when launching Audacity.

The error was:

“The system has detected that another copy of Audacity is running.”

However, Audacity wasn’t running at all. Not one process. It turned out to be just a locked file located in /var/tmp/audacity-[your-username].

All you have to do is delete the entire directory and rerun Audacity.

rm -rf /var/tmp/audacity=[your-username]/

rm -rf /var/tmp/audacity=[your-username]/

Once deleted, Audacity starts right up with no issues.

Bash Variables

June 27, 2020

Here’s how to read Bash variables from another file.

Contents of config.sh

#!/bin/bash
var1='thisisvariableone'
var2='thisisvariabletwo'

#!/bin/bash var1='thisisvariableone' var2='thisisvariabletwo'

Call config.sh from another script.

#!/bin/bash
source config.sh
echo var1
echo var2

#!/bin/bash source config.sh echo var1 echo var2

This is extremely helpful if you have multiple scripts using a common variable. You just to update one file instead of multiple files. All the other scripts will read and pick up the same variables from a config file. You can use this to setup your global variables.
