Ubuntu – How to install a program using a .md5 file

md5sum

This is a very basic question that probably has a very easy answer.
I am a frequent customer at humblebundle.com and some of the games
come in a format called ".md5". I understand it is a format that is used
to check an image for errors (after some very superficial googling).
Is it possible to open the file with a specific program or is it necessary
to use a terminal? Don't get me wrong, I am a fan of the terminal, but I am
a non-programming-languages-knowing kind of guy who just uses Ubuntu for the
fun of it. I would appreciate any answer.
Thank you in advance in case you are taking a look at it!

MD5 is an algorithm used, among other things, to check data integrity.

For example, read here or here for instructions on how to check if a .iso file has been downloaded correctly (there's no need to rename the files, though).

So, you should get the programs, that mainly come as .deb, .bin, or .tar.gz (but other possibilities exist), besides of the .md5 "checksum" file.

Ubuntu – Bash get MD5 of online file

You can use curl to fetch the online file:

curl -sL http://www.your.fi/le | md5sum | cut -d ' ' -f 1

To compare against another one, store it in a variable and then proceed:

online_md5="$(curl -sL http://www.your.fi/le | md5sum | cut -d ' ' -f 1)"
local_md5="$(md5sum "$file" | cut -d ' ' -f 1)"

if [ "$online_md5" = "$local_md5" ]; then
    echo "hurray, they are equal!"
fi

Ubuntu – Generate a separate .md5 file for each .fastq file in a directory

The simplest case is:

for file in *fastq; do md5sum "$file" > "$file".md5; done

That, however, will create file names like file1.fastq.md5. Extensions are basically irrelevant here, so that isn't a problem, but if you prefer file1.md5 do this instead:

for file in *fastq; do md5sum "$file" > "${file//.fastq}".md5; done
