exiftool -all:all= $FILE ; qpdf --linearize $FILE output.pdf

Images

imagemagick: mogrify -strip NAME_OF_FILE

Test with: exiftool -all NAME_OF_FILE

Try this from the terminal: grep " install " /var/log/dpkg.log

In a lot of cases it is useful to convert bitmaps like jpg, png to vector graphics like SVG or AI.

Inkscape -> Path -> Trace Bitmap

BASH

convert file.png file.pnm
potrace file.pnm -s -o file.svg

This is the best option I have found so far: find . -type f -exec sed -i 's/foo/bar/g' {} +
foo is replaced with bar.

Also quite handy to be able to search and replace filenames.

Run this in ~/composer: curl -sS https://getcomposer.org/installer | php

Put this in .bashrc: alias composer="php ~/composer/composer.phar"

A couple of notes on upgrading from PHP 5 to PHP 7.

Firstly you can try to copy your site or code to a server with PHP 7 and see how your PHP 5 application runs and then move forward. You can also try to use a tool to help you with finding code that needs to be upgraded and reading the documentation. See the links below.

You might have a couple of issues with mailR when running on a server.

When installing or after installing the r package: rJava you might encounter the following: libjvm.so: cannot open shared object file: No such file or directory

I fixed this on a ubuntu server with this command: sudo R CMD javareconf
