I use this little script to keep my aur packages up to date.

#!/bin/bash

script='
import json,sys

obj=json.load(sys.stdin)

if len(obj["results"]) > 0:
  print(obj["results"][0]["Version"])
else:
  print("unknown")
'

pacman -Qm | while read line; do
  pkg=(${line})
  version=$(curl -s "https://aur.archlinux.org/rpc.php?type=multiinfo&arg=${pkg[0]}" | python -c "$script")
  color="\e[0;31m"
  if [ "$version" == "${pkg[1]}" ]; then
    color="\e[0;32m"
  fi
  echo -e "$color${pkg[0]} ${pkg[1]} => $version\e[00m"
done

That's a pretty hefty if/elif/else block you got there. My recommendation would be for you to check out case statements.

For me it's all that sudo that's bothering me.

Edit:

elif [ "$1" = "-wep" ] && [ "$2" ] && [ "3" ]; then

I forgot to say you should add "username ALL=NOPASSWD: /usr/sbin/iw,/bin/ip,/usr/sbin/wpa_supplicant,/sbin/dhcpcd" to /etc/sudoers to be able to sudo them without password.

And i dont think there is nothing wrong with case sensitive parameters if i understood what you said.

Plus, the help message mentions "-w" and "-p" while the code checks for "-wep" and "-wpa". I don't think using "case" instead of "if" would simplify the code, though.

Nice idea. I'll keep it. Thanks for sharing.

What I meant to say was that you don't need to put all the sudos in the script, instead, remove them from the script and run the script with sudo when necessary.

And i dont think there is nothing wrong with case sensitive parameters if i understood what you said.

Just as a demonstration. Here's how the code would look cleaned up a bit. This was just a once-over clean-up, so I'm sure there are some mistakes, but the point should be obvious.

P.S., having a flag for the command line which allows the user to specify an interface would be a very good idea (not everyone uses "wlan0").

All the best,

Just some suggestions: add a --help option and do the stuff before case only if valid arguments were found.
In my opinion long args should have two dashes, to make more clearly that its a long option.

Since nvidia-smi works again for "low end" cards:
https://github.com/CFSworks/nvml_fix

I wrote a script that changes performance levels for my 9800GT with a threshold i defined.
Before i've had choppy kde effects and choppy firefox scrolling, due to the default policy being too much "conservative" and my card clocked to a very low speed when in powersave mode.
I then decided to "overclock" my powersave frequencies to an higher value, but that means more watts.

With this script is SO much better, i can keep default frequencies and switch faster.

#!/bin/bash
export LD_LIBRARY_PATH=/tmp/nvml_fix/built/319.23/

threshold=10            #switch to performance at this load
powersave=0             #powermizer=0 means adaptive mode
performance=1           #powermizer=1 means performance
curlevel=$performance   #pretend we started in performance mode
sleepmore=5            #seconds to wait between cycles when in performance mode
sleepless=0.5           #seconds to wait between cycles when in adaptive mode

while true ; do
    gpuuse=$(nvidia-smi -q --display=UTILIZATION |grep Gpu|sed  's/ //g'|cut -d ":" -f 2|cut -d "%" -f 1)
    echo gpu use=$gpuuse
    if [ $gpuuse -lt $threshold ]; then
        if [ $curlevel = $performance ]; then
            nvidia-settings -a [gpu:0]/GPUPowerMizerMode=$powersave &>/dev/null
            curlevel=$powersave
            echo switched to GPUPowerMizerMode=$curlevel ADAPTIVE 
            sleeptime=$sleepless
        fi
            else
        if [ $curlevel != $performance ]; then
            nvidia-settings -a [gpu:0]/GPUPowerMizerMode=$performance &>/dev/null
            curlevel=$performance
            echo switched to GPUPowerMizerMode=$curlevel PERFORMANCE 
            sleeptime=$sleepmore
        fi
    fi
    sleep $sleeptime
    echo current level=$curlevel
    echo -
done

Probably the two "cut" in the sed line could be simplified by just using sed, but i'm not that smart.
I will test this deeper, and if it really works as it is doing right now, i'll make a .service file.

A little program I use to automate installation. I have a laptop and netbook and I often reinstall Arch on them (I like changing desktop environments, and if I have a desktop with KDE, then replace it with MATE, often I end up with little programs which end up clogging stuff up, such as Amarok, which is not in anything like kdemultimedia-amarok, so I forget to remove). It can be found at https://github.com/ThatPerson/ANI.
In order to use it I configure the JSON file on a working computer, and run the Python script. This gives me a shell script. Then, I install the base bit (ie, Partition, mount to /mnt, and pacstrap base and base-devel, and then chroot in. Then, I can use the shell script to create users, generate locales, etc. I am planning on making it support more stuff, such as setting up GRUB, and doing keymaps, however generally I set the keymap in the desktop environment.
In the Git repo there is an example of one I used earlier, which installs the MATE desktop environment with NetworkManager.

Launches xephyr so I can debug my little WM tweaks (like pipemenus) and catch the output in the original terminal. Simple. Also useful for catching any other type of session errors in real time.

#!/bin/sh
cd
[ "$WM" = "" ] && WM=openbox
[ "$RES" = "" ] && RES=1024x768
Xephyr -ac -screen $RES -br -reset -terminate :100 2>/dev/null &

C CLI Wlan Manager
ccwm allows you to easily connect to any wlan network.
There is no need for configuration.
Uses iproute2, iw, wpa_supplicant and dhcpcd.

- Scan access points with nice output
- Connect to ESS access point (Open/WEP/WPA)
- Join to IBSS network (Open/WEP)
- Show interface info

Or wpa_cli?

#!/usr/bin/env bash
# set wallpaper using sxiv & update .xinitrc

file="${1##*.}"
extn=$(grep "$file" $HOME/.xinitrc)
line=$(sed -n '/background.[jpg|png|gif]/ {=}' $HOME/.xinitrc)
xres=$(awk '/dimensions/ {sub(/x/,","); print $2}' <(xdpyinfo))

imlibsetroot --store $XDG_CONFIG_HOME/background."$file" -s "$xres" "$1"

[[ -z "$extn" ]] && sed -i "${line}s:\(jpg\|png\|gif\):${file}:" $HOME/.xinitrc

Why adjust the filename in xinitrc every time? Just have one "wallpaper" file that is a link the the current background of choice. Xinitrc can just set the background to /path/to/wallpaper_link, and changes can made by linking wallpaper to the new file.

I'm probably missing something; but when called from imlibsetroot, the background is set as background.{jpg,png,etc}; and if I switch between formats, I either have to update .xinitrc or a symlink (which is your suggestion). Is there an advantage to the latter over the former?
