Plex is a media server which aggregates your media and allows you to access it on your home network. Installing the server is relatively simple… Installing it with Docker is even simpler. Docker also makes it easy to define a single configuration which is reusable across environments.
I’m working off a Ubuntu installation, since that is where I’m setting up my home media centre, but once docker is installed, getting Plex going should be nearly identical in any OS.
What is a Cron Job?
Cron is a Linux utility where you can setup a task in your machine to run automatically, if required in a repetitive manner at a specific time and date.
Such a task that you schedule is called a Cron Job.
If you happen to be stuck behind a corporate firewall with only HTTP proxies for external access, you might still be able to SSH out through them using the built-in
nc on *nix systems.

If you have ever needed to quickly decode or encode base64, Linux has a command line utility called base64 that works great. I’ll show you how it works!
To encode text to base64, use the following syntax:
$ echo -n 'codediary.net rocks' | base64
To decode, use base64 -d. To decode base64, use a syntax like the following:
$ echo -n Y29kZWRpYXJ5Lm5ldCByb2Nrcw== | base64 -d
Note: if on OS X, use capital D:
echo -nY29kZWRpYXJ5Lm5ldCByb2Nrcw== | base64 -D
Repacking an unpacked JAR is a little frustrating because of the folder structure
When unpacking with:
jar xvf JAR_NAME.jar
you get a
To repack the JAR:
remove old jar
get inside the folder
pack the jar referencing the parent folder
jar cf ../JAR_NAME.jar *
and you will end up with the JAR_NAME.jar in the parent folder, where the original was unpacked from, without the first folder level you would get if you had packed the folder itself.
For MySQL you can specify your user and password in local config file (
.my.cnf). This file should be in your home directory (i.e. ~/.my.cnf).
I would like to compress a log file using gzip Unix command line utility, and I would also like to keep the original file. However, when I use the gzip my-app.log command, results in modifying my log file and renaming it my-app.log.gz. How do I force the gzip command to keep original file while maintaining the original file on Linux or Unix-like system?
The gzip program compresses and decompresses files on Unix like system. You need to pass the -c or --stdout, or --to-stdout option to the gzip command. This option specifies that output will go to the standard output stream, leaving original files intact.
