#/bin/zsh
# This scripts generates a list of your installed packages,
# sorted by the number of each packages' number of deps,
# most deps at the top
# (It checks the depends file in the folder of each package
# in the local package database)

for i in $(/bin/ls -1 -d /var/lib/pacman/local/*)
do
 numberdeps=$(perl -00 -ne 'print if /%DEPENDS/' $i/depends | sed -e '/^$/d' -e '/DEPENDS/d' | wc -l)
 echo "$numberdeps $(basename $i)" >> tmpfile
done
sort -g --reverse tmpfile > pkgsbydepnumber
rm tmpfile
echo "File pkgsbynumber created."

What it says in the comments. Was just a little curiosity about the number of dependencies packages have.
(probably can use bash or others as well. Also there are probably ways to use grep/awk/sed or so for the perl part, it gets the part of %DEPENDS% and not the %OPTDEPENDS% in the depends files).

I just wrote this git pre-commit hook. It's intended for those who use git to manage their PKGBUILD files. It forbids all commits that include a PKGBUILD file when the source and install files are not either in git, or also in the commit.

Install it by putting it into .git/hooks/pre-commit and making it mode +x.

> This pre-commit hook may be disabled with `git config hooks.missingsources.allow true`

This is very clever.
I'll think about this when writing git hooks.

Daenyth · 2010-03-30 20:15:21

I googled for some example pre-commit hooks to learn from and saw a similar construction used

In the future, I plan to add md5sum checking to make sure that the if the PKGBUILD has changed md5sums for the sources, that the sources also get committed.

Been doing a front end to ngrep because friend pissed me off with constant "what to put where" questions so if someone wants it:

#!/bin/bash

#nwrap ngrep wrapper for dummies
#version (one and only) 1
#license i dont care
#deps (obviously) ngrep & dialog

#by night <no@mail.xxx>

#intro
clear

#depcheck
if command -v dialog >/dev/null && command -v ngrep; then
    
    #set up us the bomb
    ifconfig > .ndevs
    DEV=".ndevs"

    #list network devices
    dialog --title "Network devices" --exit-label "NEXT" --textbox $DEV 22 70 2>&1 >/dev/tty || exit
    rm $DEV

    #grab input
    dev=$(dialog --inputbox "Your network device (eth0, wlan0, etc)?" 8 40 2>&1 >/dev/tty) || exit
    pattern=$(dialog --inputbox "Pattern (split with '|')?" 8 40 2>&1 >/dev/tty) || exit
    ip=$(dialog --inputbox "Target host (leave blank for general traffic)?" 8 40 2>&1 >/dev/tty) || exit

    #go ninja until sigterm
    clear; printf "ngrep needs to be run as root so please enter your password below\n\n"
    if [ -n "$ip" ]; then
        su -c "ngrep -d $dev -P '' -W byline -iq '$pattern' host $ip"
    else
        su -c "ngrep -d $dev -P '' -W byline -iq '$pattern'"
    fi

#depcheck fail
else
    printf "You are missing one of these deps: dialog and/or ngrep.\n"; sleep 1; printf "Bye!"; sleep 1; clear
fi

exit 0

nightchill, hmm looks interesting. I think I may have done something similiar with grep but the script had some flaws and I don't use it much any more. Is this script to make searching through files. For my script with grep I created a syntax 'grop <pattern> <location>'. Is this what you're trying to do here? Also, why the use of ngrep besides regular grep?

ngrep is grep features for network so you can match your patterns against payload of packets. So this script doesn't search thru files, basically doesn't do anything you couldn't make ngrep to do if you do man ngrep. But like I said, my friend couldn't do even that so I wrote this basic interface to ngrep with some formatting options included.

I've got this as a function in my .zshrc file, here it is as a standalone script:

#!/bin/zsh
if [ $# -eq 2 ]
then
    if [ $(2#*.} = "pdf" ]
    then
        pdftotext -q -nopgbrk "$2" - | grep --color=always -niEe "$1"
        return 0
    else
        searchpath=($(ls $2/**/*.pdf))
    fi
elif [ $# -eq 1 ]
then
    searchpath=($(ls **/*.pdf))
else
    echo "Usage: pdfgrep PATTERN [FILE|DIRECTORY]"
fi

for i in $searchpath
do
    results=$(pdftotext -q -nopgbrk "$i" - | grep --color=always -niEe "$1")
    if [ $results ]
    then
        echo -e "\nFile: $i"
        echo -e "$results"
    fi
done

I call it pdfgrep. Not really sure if I'll dedicate more time into making it more efficient (how it handles parameters). Zsh's extended globbing needs to be enabled.

It's a function/script that greps pdf files. If you provide a file, it'll grep that particular file. If you provide a directory or only a pattern, it recursively greps the directory. Might throw in an option to turn off the recursive search.

Just wanted to post here about my script, screenFetch, which is written totally from scratch in Bash.

Links for it:
http://aur.archlinux.org/packages.php?ID=36072
http://github.com/KittyKatt/screenFetch

It's my first big project, so I'm kind of excited to share it. ^^

Here's some for stuff I've got sitting around!

My Random Wallpaper Snippet (wallchange)

#!/bin/bash
# Change the line below to the
# directory that has your wallpaper
# images
WALLPAPERS="$HOME/.wallpapers"
ALIST=( `ls -w1 $WALLPAPERS` )
RANGE=${#ALIST[*]}
SHOW=$(( $RANDOM % $RANGE ))

feh --bg-scale $WALLPAPERS/${ALIST[$SHOW]}

A small MPD status/control for the PekWM root menu that I hacked together

#
# This script depends on py-libmpdclient2 which you can get from 
# http://incise.org/index.cgi/py-libmpdclient2
#
# Usage:
# Save this script as "mpd.py" in the folder ~/.pekwm/scripts/ and make it
# executable ("chmod +x ~/.pekwm/scripts/mpd.py" in terminal).
#
# Put an entry in ~/.pekwm/menu wherever you would like it to be displayed:
# Submenu = "MPD" {
#      Entry { Actions = "Dynamic /home/YOURUSERNAME/.pekwm/scripts/mpd.py" }
# }
#
# Please also make sure to replace the YOURUSERNAME above with your actual username
# in /home and replace all YOURUSERNAME values in the following code with your actual
# username in /home.
#
# Yes, I do know that some of this is awful coding. I'll fix it up as soon as I have time.

I use the following code to place that script in my ~/.pekwm/menu file:

Entry { Actions = "Dynamic /home/YOURUSERNAME/.pekwm/scripts/mpd.py" }
}

I've got some more laying around. I host the good ones on my site at http://www.silverirc.com/kittykatt/inde … ge=scripts

@dwm: Some nice scripts there! I like the MPD ones. I'm working on a MPD song change monitor myself at the moment.

Ah! Just found this one lying around. It's a script to output current disk usage in conky. Uses the Poky font, which can be found on my server. Download here.

#!/usr/bin/env python
import sys
import os
import subprocess

# root filesystem
print "${voffset -2}${color0}${font Poky:size=15}y${font}${color}${offset 6}${voffset -7}Root: ${font Liberation Sans:style=Bold:size=8}${color1}${fs_used_perc /}%${color}${font}"
print "${voffset 2}${color0}${fs_bar 4,20 /}${color}${offset 8}${voffset -2}F:${color2}${fs_free /}${color} U:${color2}${fs_used /}${color}"

# /home folder (if its a separate mount point)
if os.path.ismount("/home"):
    print "${voffset -2}${color0}${font Poky:size=15}y${font}${color}${offset 6}${voffset -7}Home: ${font Liberation Sans:style=Bold:size=8}${color1}${fs_used_perc /home}%${color}${font}"
    print "${voffset 2}${color0}${fs_bar 4,20 /home}${color}${offset 8}${voffset -2}F:${color2}${fs_free /home}${color} U:${color2}${fs_used /home}${color}"

# Add extra mounts that aren't / or /home and aren't in /media
# if os.path.ismount("/path/to/mount"):
#     print "${voffset -2}${color0}${font Poky:size=15}y${font}${color}${offset 6}${voffset -7}Music: ${font Liberation Sans:style=Bold:size=8}${color1}${fs_used_perc /path/to/mount}%${color}${font}"
#     print "${voffset 2}${color0}${fs_bar 4,20 /path/to/mount}${color}${offset 8}${voffset -2}F:${color2}${fs_free /path/to/mount}${color} U:${color2}${fs_used /path/to/mount}${color}"

# folder in /media
for device in os.listdir("/media/"):
    if (not device.startswith("cdrom")) and (os.path.ismount('/media/'+device)):
        print "${voffset -2}${color0}${font Poky:size=15}y${font}${color}${offset 6}${voffset -7}"+device.capitalize()+": ${font Liberation Sans:style=Bold:size=8}${color1}${fs_used_perc /media/"+device+"}%${color}${font}"
        print "${voffset 2}${color0}${fs_bar 4,20 /media/"+device+"}${color}${offset 8}${voffset -2}F:${color2}${fs_free /media/"+device+"}${color} U:${color2}${fs_used /media/"+device+"}${color}"

Include it in conky using "${execpi python /path/to/conkyHD.py}".

Non-Relevant: I loaded my website to copy the source of that script and saw one of my random BOFH excuses pop up that I thought I would share because it made me laugh...

"BOFH excuse #184: loop found in loop in redundant loopback"

This is a small, ugly, hacky Bash calculator I worked on last year that I just now found. Needs loads of improving and cleaning, if someone's up to it.

Just wrote up a small libnotify interface for MPD using mpc, though it could be modified quite easily to fit most of the other console music players. You have to change the naming layout of your cover-art and the folder in which your cover-art is stored. This doesn't currently support downloading the cover-art when it's not found. Feel free to

I used the bashnotify daemon written by brisbin33. Thread can be found here.

I modified brisbin33's script to write MY original config when none is found instead of the one specified before. This gets rid of the need for a separate config file to be posted here, as the script creates it. I've also changed where it creates it to $XDG_CONFIG_HOME, which for me at least is ~/.config on this install.

Thanks for the template brisbin33.

kittykatt, nicely done. just be careful, in writing your config file you have:

# $mydir exists, and it's value is /home/kittykatt/.bashnotify

will result in:

# /home/kittykatt/.bashnotify exists, and its value is /home/kittykatt/.bashnotify

as $mydir will be evaluated. i think in the original i had this:

# \$mydir exists, and its value is $mydir

also, i rewrote your calculator a bit if you don't mind:

Great! Yeah, I modified the original config quite a bit and didn't realize until later a couple of things that you did. Then, I promptly forgot them again while posting this. >.< I'll tweak the original to include that. Did you like my truncating? That was a new thing for me.

Edit: Funny, how I found that in the RIGHT syntax in my personal version. I must have fixed that and just forgot to update it in this post before submitting it.

Also, do you think we might hack something together to act on certain events, like hooks? Because when I do something like "mpc clear" in a terminal, I get this huge output in a notification and it's quite annoying, as I do that quite often. I'd like to only show this notification on certain events (next, previous, play, pause).

i think this is a limitation of mpc itself. the idleloop functionality is a bit lacking. `mpc idleloop player` is as specific as i could get (hoping it only threw output on track changes or play/pause type events). if you just do `mpc idleloop` you can see what it outputs for what events. this output would be the only means of calling various hooks on various events (or choosing to ignore/act). but like i said, it appears to be a bit lacking and very nonspecific.

You know what the sad part is? I already knew that, but I completely forgot about using that. -goes about shortening code-

I'll have to have a look at that in a few minutes. I think if it throws out at least a couple of unique statuses, I can improve the functionality of this tenfold.

Edit: BUH. Yeah, idleloop is very bare bones. Hm. Gotta figure another way around this one....

uses conkyeEmail to check my gmail and then uses xbmc-send notifications to tell me, i added some checking against the last run so its doesnt give repeated notifications, i have it running every 20min via cron.

#!/bin/bash
emails=$(conkyEmail --servertype=IMAP  --servername=imap.gmail.com --ssl --username=*** --password=***)
emaillog=~/.email.log

if cat $emaillog | grep -q $emails ; then
echo no new emails since last run
else
xbmc-send -a "Notification([Gmail], You have $emails new message(s))"
fi

echo $emails > $emaillog

I store my passwords in a key–value pair file like this:

key value
key value
key value

I've written this little script that sends a password of a given key to the clipboard. You can then enter "get-password.sh twitter". Browsers usually remember this, but it has happened a few times that I've lost them. "chown root" the passwords file and change its mode to 600.

#!/bin/sh
sudo cat ~/path/to/password/file | grep $* | cut -d ' ' -f 2 | tr -d '\n' | xclip

Please give me some feedback if you notice any security issues with this script. Hashing would make it more secure, but I'm not good at that stuff.

Hashing wouldn't really help in this situation, but a simple encryption system might be good. Like create an encrypted password vault using encfs or gpg. Here's an example that might help. Keeping that file in plain text, even if it's owned by root, isn't a good idea. You'll have to remember a single master password, but it's better than plain text.

Make a wrapper script around it that invokes gpg

Cool stuff. I don't have time to look at it right now, but that would be perfect.
