## Scripts



a collection of personal scripts. A few worked way back in time, some need a complete rewrite but 90% are perfectly usable.



#### backlight\_change.sh



Increase or decrease the screen's backlight. Should work with any backlight driver



####  bigpkg.py



List Archlinux's installed packages by size. By Allan McRae



#### cert-hashing.sh



Hash a SSL certificate



#### clitwitter.py



Old script to post on Twitter with Basic Authentication. Need to be updated with

OAuth but I've since switched to TTYtter



#### compare\_images.py



A script to compare images in a directory for similarity. It returns 

only those similar but not identical in a list. At this moment the list 

contains all images that have at least another very similar but doesn't 

check if they are similar with all the other images in the list, ending 

up with different couples of similar images but not all very similar. I 

found it too long to loop again and again to check all the images among 

themselves or return different lists for each group of similar images



#### cortex\_reddits.py



Browse (sub)reddits with the Reddit client cortex. Totally an hack, subscribing 

them on Reddit is much easier but I didn't want to read all my subscriptions 

each time so I wrote this script to choose what and when to browse



#### csv\_to\_md\_files.py



A script, not mine, that converts a CSV file to a series of markdown files 

based off the first column of the CSV file. It is useful to export sheets from 

Excel or GDocs to markdown to be edited then in Obsidian



#### dayoftheweek.py



Not my script originally, I just made it Python 3.2 compatible



#### delete\_by\_percentage.lua



Delete a random choice of files in a directory by a given percentage. Seems 

totally pointless but you'll never imagine the use case that made me write it... 

:)

Deploy script for dotfiles here on Github. Untested.



#### dizionario\_sqlscript.lua



Search and insert words and definitions in a SQLite dictionary of multiple 

languages

terminals. It checks whether a url is to an image, and open it in feh, or to 

something else, and open it in the browser



#### fehgallery.lua and fehgallery.py



Sort images in a directory and feed them to feh. Also, delete feh's filelist 

files if present. Same script written in Lua and Python

#### hdbenchmark.sh



A very raw HD benchmark tool



#### i3lock-script.sh and i3lock-dracula-script.sh

too fancy, mostly copied from the official repo and from the [dracula theme 

repository](https://github.com/dracula/i3lock-color) for i3lock-color.



#### imap\_check.py



CLI unread count of my 2 GMail accounts. I used this as input for an AwesomeWM

#### script\_disable\_touchpad.sh



Launched at boot from your WM/DE, it detects thanks to xinput whether a 

mouse is present or not and disable/enable the touchpad accordingly. It 

goes along with the udev rules, completing it as with udev it can only 

be detected when a mouse is plugged in or off, not when it's already 

plugged in at boot. "Lachesis" is my mouse, of course



#### script\_dl\_single\_github\_file.sh



Download a single file from a specific repository on Github



#### script\_dos\_unix.sh



Convert Dos/Unix newline format



#### script\_download\_images.sh

#### script\_efi\_menu\_restore.sh



Restore UEFI boot menu entries. Of course only those I use/care about

Save the flash video opened in firefox. Not working with all files/sites

remember the name. Of course I've only added those I find more useful



#### script\_private.sh



Mount my private, cryptsetup encrypted partition and start the MPD daemon. 

Automatic detection of different partition, on desktop or laptop



#### script\_proxy\_checker.sh



Check whether a proxy is working and is from the US by trying to access 

pandora.com (as it is blocked here in Italy, if I can access it it must be an US 

address)



#### script\_rate\_music.sh



Add currently playing song in MPD to a playlist using ncmpcpp or cmus (quite 

easily expanded for other players). The original script allowed only to rate 

songs in aptly named playlists (1 to 5) but this permits to use any name for the 

playlist



#### script\_ripencode.sh



Audio cd ripping script (to mp3, ogg or flac)



#### script\_touchpad.sh

Tweets current playing song (from ncmpcpp) via TTYtter. This must be configured

This is a old script, but still working, that I used when I did some video 

editing. Basically it generates an image containing informations such as 

filename, size, lenght and codec of a video along with a series of thumbnails to 

show off its content. I never tweaked it more than "black backround, fixed 

spacing between thumbs" though, I just needed something that didn't force me to 

depend on external programs.

#### script\_zfs\_private.sh



A script to mount an encrypted ZFS dataset. Mostly the equivalent of script\_private.sh



#### showip.c



Show IP addresses for a host



#### sopcast.go



A launcher for Sopcast streaming links. I had a Bash function for this

Timer and service to clean ImageMagick's temporary files created in /tmp and not properly cleaned (see issue [395](https://github.com/ImageMagick/ImageMagick/issues/395))

Systemd service for wired networks



#### systemd/overwrite-hosts.service and systemd/overwrite-hosts.timer



A service and timer couple to overwrite every 10 minutes the /etc/hosts file

with a copy that is on one of my personal directories. That's because the file

it's automatically generated by copying blacklists from the internet of

advertisement/malware/adware/etc. to ban every few minutes and I need

/etc/hosts to be synced with this updated file



#### systemd/stash.service



A systemd service to run stash app as a server (on a Raspberry Pi in my case but can be ran anywhere)

#### ttytter\_startup.sh



Old shell TTYtter startup script that I used before switching to Systemd. It 

checks whether a tmux session containing TTYtter is already running and 

reattaches to it or if it's not, launch one. This is for WM that are launched by
