HopeSeekr's Bash Scripts

Utilities to ease your life.

Scripts that I use on a daily basis, or on new system installs, that improve my experience with Linux substantially!

bash_rc.aliases

This is arguably the most important piece of the project!

These dozens of aliases make working with Linux and developing web app software much more efficient and streamlined.

changelog-maker-lite

gitconfig

Install into ~/.gitconfig.

git pretty
git ll

Shows a beautiful multi-colored log with standard ISO dates:

git fix

Quickly jumps into rebasing the last two commits into one another.

git alterego

Quickly switch the current repo to using your main alterego account for an previously-committed commit.

git ego

The reverse of git alterego.

git resign <hash>

Quickly resign bulk commits from to the latest.

This is particularly utilitarian when your GPG key expires and you need to renew it and then resign.

git c: checkout
git cp: cherry-pick
git cpm: cherry-pick for Merge commits

Utility aliases to make git more efficient to use.

git shows

Shows the GPG signature for every commit in git log.

sudoers.d/00_prompt_once

This will make sudo only ask for your password ONE TIME during a single boot. It won't ask across terminals and it won't time out. On reboot, it will automatically expire.

cron.daily/00_clear-cache

Empties out the ~/.cache directory of every non-root user.
Empties out Pacman's package cache directory.

This can optionally use nullfsvfs in order to limit wear-and-tear on SSDs.

cron.daily/01_purge-locales

Removes every non-EN locale file every day.

This saves, usually, 400-1000 MB of space.

cron.hourly/btrfs-snapshot

Takes BTRFS snapshots of / every hour on the hour.

cron.daily/btrfs-snapshot

Cleans up the prior day's hourly snapshots while keeping the daily ones.

clone-github-repos.php

Automagically downloads all of the GitHub repositories of a user or or an organization.

init-btrfs-rootfs

The Problem

Arch Linux sticks all of / in the main BTRFS subvolume (ID=5).

This means that common snapshotting and subvolume tasks, particularly rolling back to a previously (e.g., working) root subvolume is exceptionally difficult and requires a rescue boot, etc.

The Solution

The provided solution hotfixes the situation, hopefully without the need for a rescue disk, on a live environment. However, you really ought to have a rescue disk prepped in avance.

And for the love of God, make backups first!

ls-by-min

Returns a list of files sorted by file size, descending, that are at least X MB big.

random-file [dir]

Picks a random file in a directory / PWD.

sync-watch

Displays how many megabytes still need to be written to [slow] disks.

watermark.sh

Adds a watermark to videos via ffmpeg.

x265.sh

Transcodes to x265 HEVC via ffmpeg using Intel's graphics card.
