rsync from one remote to another remote, only local computer has an open ssh key

rsync by itself doesn't support copying between two remote hosts, but if you use sshfs you can pretend one of them is local. If you have a passphrase-less ssh-key, you can even put this script into a cron job.

A faster alternative is to run ssh-keygen on remote1 and put the pubkey into remote2:~/.ssh/authorized_keys, running rsync on remote1 (or vice versa), but the problem with that is that now a hacker on remote1 can access remote2 at any time. The above method ensures your local computer stays the weak link.

bash function to highlight non-printing characters: tab, newline, BOM, nbsp

Can't see it here, but the non-breaking space is highlighted :)

Of course,

cat -t -e

achieves something similar, but less colourful.

Could add more code points from https://en.wikipedia.org/wiki/Space_%28punctuation%29#Spaces_in_Unicode

hl-nonprinting () { local C=$(printf '\033[0;36m') R=$(printf '\033[0m'); sed -e "s/\t/${C}▹&$R/g" -e "s/$/${C}⁋$R/";}

bash function to "highlight" tabs and linebreaks

I don't think it's possible to give a (background) colour to the tab itself, since a tab is, IIUC, simply a command to the terminal to move to the right. Nevertheless, this "highlighting" can be helpful when working with tab-separated files.

free some harddrive space by garbage collecting in all your git repos

Assumes you've cd'd to the folder in which all your git repos reside; you could run it from ~ without -maxdepth, although that might make find take quite a while longer.

If you have several processor cores, but not that much ram, you might want to run

git config --global pack.threads 1

first, since gc-ing can eat lots of ram.

diff two css files to create an overriding css (e.g. for wordpress child themes)

This will extract the differing CSS entries of two files. I've left the initial character (plus or space) in output to show the real differing line, remove the initial character to get a working CSS file. The output CSS file is usable by either adding it in a below the to original.css, or by only using the output but adding @import url("original.css"); in the beginning.

This is very useful for converting Wordpress theme copies into real Wordpress child themes.

Could exclude common lines within entries too, I guess, but that might not be worth the complexity.
