What is an aur binary repository? If midrepo is a regular repo, why not just run 'pacman -Syu'?

It's for when you don't want to compile the same program on every machine, you just create a repository and build stuff once.
I basically compare the version on the repo with the aur.

If you have these packages installed, you can do this directly with an AUR helper.

Yaourt -Syua only checks for AUR updates on foreign packages (listed with pacman -Qm).
That said, I haven't tried it with any other AUR helper.

This is essentially the same as what I'm using for indicator-session-systemd, just a little stripped down.

It provides handy shortcuts to hibernate, suspend, shutdown, and reboot that don't require a password

#! /bin/bash
# Shortcuts to systemd/logind's dbus session management

case "$1" in
	logout|quit|exit)
		SESSIONID=$(gdbus call -y -d org.freedesktop.login1 -o /org/freedesktop/login1 -m org.freedesktop.login1.Manager.GetSessionByPID $$ | sed -nr '/.*session\/(.{,2}).*/s//\1/p')
		# gdbus will throw and IO Error if sending more than two arguments,
		# even if the method requires three or more like KillSession.
		# Only root can kill sessions.
		sudo loginctl kill-session $SESSIONID
		exit # curious if this exit actually happens...
	;;
	suspend|standby|sleep)
		METHOD="Suspend true"
	;;
	hibernate)
		METHOD="Hibernate true"
	;;
	reboot|reset)
		METHOD="Reboot true"
	;;
	shutdown|poweroff)
		METHOD="PowerOff true"
	;;
	*)
		exit
	;;
esac

gdbus call -y -d org.freedesktop.login1 -o /org/freedesktop/login1 -m org.freedesktop.login1.Manager.$METHOD

Only root can end a session, so logout still requires a password.

The last two days I learned about httpie and jq; can't help using when a chance like this hits me in the face:

http -bf http://pomf.se/upload.php "files[]@$image" | jq -r '"http://a.pomf.se/\(.files[].url)"'

Thanks lolilolicon: I saw jq on Lobsters (yesterday or today?) but hadn't come across httpie before. jq certainly seems simpler than jshon, but the advantage(s) of httpie still eludes me...

#edit: other way around: httpie is still on the front page (although I hadn't read it), not sure where I saw jq...

I'm not sure about jshon, but I feel jq is quite powerful/ambitious.
The main thing I see in httpie is a more convenient syntax, pretty output formatting, and --session feels nice too -- but it's absolutely not as powerful as curl. For example httpie seems not to be able to attach more than one file in a multipart form POST.
So, I've abandoned httpie for this script; here's my version:

#!/bin/bash

declare -a formparams
for image in "$@"; do
  formparams+=(-F "files[]=@$image")
done

response=$(curl http://pomf.se/upload.php "${formparams[@]}")
if [[ $(jq -c -r '.success' <<< "$response") == true ]]; then
  jq -c -r '"http://a.pomf.se/\(.files[]|.url + "  " + .name)"'
else
  jq -c -r '"Failed: \"\(.error)\""'
  exit 1
fi <<< "$response"

By the way, this site is really rude!

That's pretty tidy...

jq is somewhat powerful: I was able to put the if-else logic inside the jq "script"; here's the v2:

@!/bin/bash

declare -a formparams
for file in "$@"; do
  formparams+=(-F "files[]=@$file")
done
curl http://pomf.se/upload.php "${formparams[@]}" | jq -c -e -r '

A CLI reddit listing, not pasting the code here since it contains non-printing characters (\x1b) used for color/underline. Download it here:

curl http://a.pomf.se/nhkudf.txt -o reddit.sh

Opionally, you can pass r/<subreddit> as $1.

Edit: updated http://a.pomf.se/asfwml.txt (`empty` seemed to do something different from I expected).

@Earnestly, ~~that's not perfect either, e.g. name could include white spaces~~. I'm sure Jason simply wanted a quick fix-up, something that was enough for his uses.

Edit: oops, I guess name is on its own line? didn't test, sorry mate.

Humour me: how am I calling them multiple times? Or do you mean if I wanted to run it against more than one image?

simple script to convert a github.com url to a git.io url (of your choosing as opposed to a random one)

#!/bin/sh
echo -e "repo url:"
read repo
echo -e "short link:"
read link
curl -i http://git.io -F "url=$repo" -F "code=$link"

example:

[~]── - bash gitio.sh 
repo url:
https://github.com/syntax-samurai/ryu
short link:

I'm not sure how many people want to replace truecrypt container files but, this is what I use. First you have to make a LUKS encrypted file using mount loop. This doesn't do that but, I don't do that very often. This makes it easy to mount the file which I do a lot more often. It requires the filename as the first argument on the command line. What it does is mount the file and prompt to dismount it. Until you answer that prompt, the file is available for use.

#!/bin/bash

# Verify that running as root
if [[ $UID -ne 0 ]]
then
  echo "$0 must be run as root"
  exit 1
fi

# Verify file exists
if [ ! -e $1 ]
then
	echo -e "$1 not found"
	exit 1
fi

# Find an available loop device and parse out name to use
loopdev=$(losetup -f)
loopnm=${loopdev##*/}
echo -e "Loop device $loopdev"
echo -e "Will mount $1 at /mnt/$loopnm"

# Create the loop device and open the encrypted container
losetup $loopdev $1
cryptsetup luksOpen $loopdev $loopnm

# Mount the encrypted file
if [ ! -d "/mnt/$loopnm" ]
then
	mkdir /mnt/$loopnm
fi

mount /dev/mapper/$loopnm /mnt/$loopnm
echo -e "\n$1 mounted at /mnt/$loopnm"

# Prompt then dismount
while true
do
	echo -e "\nPress enter to dismount"
	read junk
	umount -f /mnt/$loopnm && break
done

rmdir /mnt/$loopnm
cryptsetup luksClose /dev/mapper/$loopnm
losetup -d $loopdev
echo -e "/mnt/$loopnm dismounted and $loopdev available"

Using pam to create a "live" MOTD

This uses pam to run a script on login, here to give a "live" MOTD reflecting information on machine status I want to know when I first login to a console.

The script is what I use (just by way of example):

#!/bin/bash
echo ""
echo "Welcome to ${HOSTNAME}, ${PAM_USER}"
echo "Kernel:     $(uname -r)"
echo "Uptime:     $(uptime -p)"
echo "SSID:       $(iw wlp2s0 link | awk '/SSID/ {print $2}')" 
echo "Iptables:   $(systemctl is-active iptables)"
echo "Disk Use:  $(df --output=pcent / | sed 1d)"
echo "Battery:    $(upower --show-info /org/freedesktop/UPower/devices/battery_BAT0 | awk '/percentage/ {print $2}')"

Note the use of the variable $PAM_USER rather than $USER; if you want to print the user name or disk usage in $USER's home, you need to use $PAM_USER rather than $USER.

You then need to modify your /etc/pam.d/system-login file to add the following line:

session    optional   pam_exec.so          stdout /path/to/your/script/scriptname

Now your MOTD will really give you "news you can use" about the current system state.

I learned about this in this systemd-devel thread.

EDIT: Corrected SSID and Battery items per Steve's suggestion below. Thanks Steve.

To have awk match a word on a line, the syntax is:

 awk '/word/ {print $2}'

This will allow you to remove the greps.

Just a little script to import your Keepass 1.x database into GNU pass without needing to export in plain text/xml from keepassx. No GUI required, just:

pip install --user kppy
python keepass_kppy_pass.py <db name> [--keyfile <db key file if necessary>]

This script will convert the sepcified manpage to HTML with Arch Wiki's beautiful CSS and open the result in your $BROWSER. Here's a preview image.
The only requirement is: https://aur.archlinux.org/packages/mdocml/
Usage:

./<this script> <section name> <manpage name>

For example:

./<this script> 8 pacman

Latest version at https://github.com/axper/man2archwiki

#! /usr/bin/env python3
# -*- coding: utf-8 -*-
''' This program converts a manpage to HTML with Arch Linux Wiki's CSS style.
    It uses mandoc (aka mdocml) for HTML convertion.
    The resulting file is then opened in a $BROWSER.

    Required arguments are section number and manpage name, for exmaple:
        ./<this script> 8 pacman

    Section number is required because I can't figure out how to specify
    2 poisitional arguments in argparse, with one of them non-required.

A simple script to run something loads of times and tell you the average execution time. I wrote it to prove/decide between different methods of achieving the same thing e.g. how much difference between shell inbuilt commands and the same from /usr/bin (there is a *lot* of difference!)
...and "zcat file.gz | grep words" is faster than "zgrep words file.gz"

Up-to-date should always be available from: GitHub

Current:

#!/bin/bash
#
# benchmark-exec-time.sh - Run a command n times and show average exec time
# 2014-06-28 Steven Honeyman 
#
# Usage: benchmark-exec-time.sh <numRuns> <command>
#

if [[ $# -lt 2 ]]; then
    echo 'Usage: benchmark-exec-time.sh <numRuns> <command>'
    echo ' $ benchmark-exec-time.sh 100 sleep 5'
    echo ' $ V=1 benchmark-exec-time.sh 10 testscript'
    exit 1
fi

logFile=$(mktemp benchmark-XXXXX.log)
TIMEFORMAT="%3R"
total=0
numRuns=$1; shift

for r in $(seq 1 $numRuns); do
    [ ! -z $V ] && echo "run $r... "
    { time $@ >/dev/null || exit 1; } 2>>$logFile
done

echo " Done. calculating..."
while read i; do
    total=$(bc<<<"$total+$i")
done < ${logFile}
rm $logFile

echo " Completed $numRuns runs of: '$@' in $total seconds"
echo " Average run time was: $(bc<<<"scale=3;$total/$numRuns") seconds"

This script will convert the sepcified manpage to HTML with Arch Wiki's beautiful CSS and open the result in your $BROWSER. Here's a preview image.
The only requirement is: https://aur.archlinux.org/packages/mdocml/
Usage:
./<this script> <section name> <manpage name>
For example:

This is awesome!! Thank you!!

This sounded neater in my head Shows a list of missing files, but taking into consideration NoExtract settings from pacman.conf

pacman -Qk 2>&1 | awk '{if(NR==FNR){ if($0~/^NoExtract/)for(i=0;i<=NF;i++){if($i!~/^NoExtract|=|^!/){gsub("/","\\/",$i);gsub("\\.","\\.",$i);gsub("?",".",$i);gsub("*",".*",$i);a[$i]++;}}}else{m=0;if($1~/^warning/){for(r in a){if($3~r){m=1;break}};if(m==0){print "MISSING "$3}}}}' /etc/pacman.conf -

(inspired by https://bugs.archlinux.org/index.php?do … k_id=41028 )

As a sysadm I've found this script useful in my daily work:

# ChangeLog script v. 0.4 -  Ashren

chlogpath="/ChangeLog"
 
if [[ -z "${SUDO_USER}" ]] && [[ $UID != 0 ]]; then
    echo "Please use sudo or root."
    exit 1
fi
 
if [[ ! -a $chlogpath ]]; then
    echo -e "\nChangeLog for ${HOSTNAME}" >> $chlogpath
fi
 
if [[ -z "${SUDO_USER}" ]]; then
    read -p "Please enter initials: " init
    sed -i '1i '"$(date)"' '"$init"'\n\n\n' $chlogpath
    vi +3 $chlogpath
    exit 0
else
    sed -i '1i '"$(date)"' '"$SUDO_USER"'\n\n\n' $chlogpath
    vi +3 $chlogpath
fi
