Say you have a large amount of data you want to send in a folder, say /path/to/large/data. Make a new folder, somewhere it can be accessed by your recipient, by FTP / scp / ssh / HTTP, whatever. E.g. /other/path/to/parts. Then do:

SOURCE="/path/to/large/data"
DEST="/other/path/to/parts"
tar cf - "$SOURCE" | gzip | split -da6 -b10M - "$DEST"/part.
sha1sum "$DEST"/part.* >"$DEST"/checksums.txt

Be careful to omit trailing slashes, as in the first two lines above.

One time,

echo -e '\usepackage{extsizes}\n\usepackage[margin=0.25in]{geometry}' >extsizes.inc

because -V geometry:margin=0.25in is ignored for some reason.

Then

 --include-in-header extsizes.inc -V documentclass=extarticle \

Apache Guacamole using Docker to put your personal desktop on the web

This guide doesn't cover security issues at all.
This guide is intended to just get your personal desktop onto the web so you can use it remotely, it doesn't cover serious multi-user Guacamole deployment.
At the end of this file there are some notes on installing docker, running a VNC server, and setting up a web proxy, but this guide really isn't meant to cover those topics.
This guide is based on [Installing Guacamole with Docker

A sed solution that selects a column by number:

echo 0 1 2 3 iv 5 6 | sed -E 's/^(\S+\s+){4}(\S+).*/\2/'

or
