Post your handy self made command line utilities

Being fed up with XScreensaver's lack of proper API for switching on/off, I decided not to use "heartbeat_cmd" command in MPlayer (because it results in serious glitches during playback), and invented a simple script called "sm". Here it is:

#!/bin/sh
rm ~/.xscreensaver; ln -s ~/.config/xscr-stub ~/.xscreensaver; (xscreensaver-command -restart &); smplayer $@
if top -b -n1|grep -q smplayer; then true; else rm ~/.xscreensaver; ln -s ~/.config/xscr-main ~/.xscreensaver; (xscreensaver-command -restart &) fi

As you see, it requires two files in .config subdirectory of your home dir. First is xcsr-main - a "normal" XScreensaver config. Second is xscr-stub - a config that says XScreensaver is switched off.
When an instance of SMPlayer is closed, the script does not switch XScreensaver on unless it was the last instance.

I hope you don't mind, I rewrote your little script (which i like very much btw) to use zenity (this is purely a personal preference) and not to use a temporary file. I thought you might like it

Nice Phil, I will have to try it out. Surely, your script must be "better" than mine. At least you made an active choice on which GTK+ window drawer to use. I just use the only one I knew about

I also liked the idea and also wrote my own, in python. Pypres is a small utility for enabling external displays based on presets, intended to be used with the "Presentation" media button found on many laptops.

It looks very neat. Is there any advantage in using Python for this? I think Emacs support Python out of the box so I might also have a look at your script. If nothing else than for the cool logo

A small script to convert AVI files in to a DVD.

#!/bin/bash
##$1=input file
##$2=output file 
mkdir $2
/usr/bin/mencoder -srate 48000 -af lavcresample=48000 -speed 25025:24000 -oac lavc -aid 1 -ovc lavc -of mpeg -mpegopts format=dvd:tsaf -ofps 25 -vf expand=640:360:0:44,scale=720:576,harddup -lavcopts threads=2:vcodec=mpeg2video:trell:mbd=2:sc_threshold=1000000000:cgop:vstrict=0:vrc_maxrate=8500:vrc_buf_size=1835:vbitrate=5001:keyint=12:acodec=ac3:abitrate=224:aspect=16/9 -o $2/$2.mpg $1
cd $2
dvdauthor -o $2 -t *.mpg
dvdauthor -o $2 -T
mkisofs -dvd-video -o $2.iso $2/
wodim -v dev=/dev/cdrom $2.iso

Usage: dvdconvert.sh /path/to/file.avi outputname

i just came up with this to day, its in the middle of burning the disk, im confident it will play in a dvd player, but im gona test the disk, then report back.

edit0: it plays, but it has messed up the size of the screen, insted of having 2 bars, 1 at the top and bottom. it has a giant black bar at the bottom, How do i make mencoder encode the video without changing the aspect ratio or moving the black bars around?

edit1: i have changed the mencoder options, it should work better now

Very nice code, I've not taken a real look too much into it yet, but please try this edit, which I made so I can run it right from nautilus:

#!/bin/bash
cd $(dirname "$1"); ## this makes things easier later on.
in=$(basename "$1"); ## because otherwise .'s in directories cause problems
out=${in%.*}; ## here.

mkdir "$out"

/usr/bin/mencoder -srate 48000 -af lavcresample=48000 -speed 25025:24000 -oac lavc -aid 1 -ovc lavc -of mpeg -mpegopts format=dvd:tsaf -ofps 25 -vf expand=640:360:0:44,scale=720:576,harddup -lavcopts threads=2:vcodec=mpeg2video:trell:mbd=2:sc_threshold=1000000000:cgop:vstrict=0:vrc_maxrate=8500:vrc_buf_size=1835:vbitrate=5001:keyint=12:acodec=ac3:abitrate=224:aspect=16/9 -o "$out/$out.mpg" "$in"

cd "$out"

dvdauthor -o "$out" -t *.mpg
dvdauthor -o "$out" -T

mkisofs -dvd-video -o "../$out.iso" "$out/"
cd ..
rm -rf "$out"

I'm planning to edit this again to handle converting multiple files at the same time(so you can highlight multiple files at once and convert them in sequence to the DVD), but I have no idea how to do that, I was thinking of dividing it up, first I create a small text file, if it exists I append to it. After say, one second, if no new changes have been made to the file we lock the file and start converting them all, if not we exit early, and leave it for whichever version of the application wrote to the file last(giving most time for other files being added incase it's running a little slow).

I'm sure there's a much better method though.

EDIT:
After testing I found some interference on the right hand side, any help fixing that? I have no idea what's causing it or what settings I'd change to fix it.

This script checks for new mail and starts mutt if there's any.

This has probably been done before, but I felt the need to script something, basic twitter status updater, uses zenity if no argument is given, if given an argument, the command line version will be invoked.

#!/bin/bash

# twitterupd: Twitter Updater
# Written badly by Kourosh Parsee 09/08/2009

MESSAGE=$1
username=
password=

gui() {
    ZMESSAGE=$(zenity --entry --title="Update Twitter" --ok-label="Update" --text "What are you doing?") || exit 0
    curl --basic --user $username:$password --data status="$ZMESSAGE" http://twitter.com/statuses/update.xml > /dev/null || zenity --error --text="Status Update Failed"
    zenity --info --text="Status Updated"
    exit 0
}

basic() {
    echo -n "You are about to set your status to: "
    echo "$MESSAGE"
    echo -n "Continue? (y/n) "
    read yn
    if [ $yn = "y" ]; then
        echo "Updating Twitter..."
        curl --basic --silent --user $username:$password --data status="$MESSAGE" http://twitter.com/statuses/update.xml > /dev/null || echo "Status Update Failed"
        echo "Status Updated"
    else
        exit 0
    fi
}

if you use remind (+ wyrd ftw!) as your linux calendar app, and you have a public gcal, then you can use this in a cron job to sync your google calendar to your .reminders file. it's a simple one-way sync but it works for me.

requires ical2rem.pl and the perl-ical-parser package.

#!/bin/sh
#
##

REM="$HOME/.reminders"
CON="$HOME/.bin/ical2rem.pl"
URL="http://www.google.com/calendar/ical/GMAILUSERNAME%40gmail.com/public/basic.ics"

wget -q -O - "$URL" | $CON > $REM

the perl script does all the work, my bash wrapper just downloads the public gcal ical file before hand. if i knew perl i'd love to get it all into one script... oh well.

/edt: came up with a way simpler way to do it

A script for easy note-taking. Can be used directly from the terminal or if you use Xmonad you can do it more elegantly. ;)

#!/bin/sh

# Starting position of text
Y=60
X=60
# Distance between lines
YSPACE=30
# Temp file containing the message count
MFILE=/home/tch/.note
# Initial wallpaper
FILE=/home/tch/wallpapers/`date +'%m'`.jpg
# Temporary file
TMPFILE=/home/tch/wallpapers/tmp.jpg
# Font and color
FONT="-xos4-terminus-bold-*-*-*-32-*-*-*-*-*-*-*"
COLOR="#c2c2c2"

if [ -f $MFILE ]; then
    FILE=$TMPFILE
    C=`cat $MFILE`
else
    C=1
    echo 1 > $MFILE
fi

Y=$(($Y + ($YSPACE * ($C - 1))))

convert -font $FONT -fill $COLOR -draw "text $X,$Y '$*'" $FILE $TMPFILE
feh --bg-center $TMPFILE
echo $(($C+1)) > $MFILE

Having a wallpaper folder where the script picks wallpapers at random Very handy if you like OpenBox and change your wallpaper often.

#!/bin/bash

DIR="/home/maister/Pictures/Wallpaper"
INTERVAL="10m"

while true
do
        RANGE=`ls "$DIR" | wc -l`
        echo "RANGE is $RANGE"
        NUMBER=$RANDOM
        let "NUMBER %= $RANGE"
        let "NUMBER += 1"
        WALLPAPER=`ls "$DIR" | head -n $NUMBER | tail -n 1`     
        feh --bg-scale "$DIR"/"$WALLPAPER"
        echo $WALLPAPER
        echo "Picked number $NUMBER"
        sleep "$INTERVAL"
done

Script to pick a random wallpaper when run. I run it from my .xinitrc

#!/bin/bash

papers=/usr/share/wallpapers/rotation/

background="$papers`ls $papers -c1 | sort -R | head -n1`"
feh --bg-scale "$background"

Rofl. sort -R basically made my whole "pick random wallpaper" script feel retarded. XD I learn something every day.

# Limitations
# Because lnk must check if the link points to a folder or a new linkname,
# if creating a link that has the same name as a directory and the link has 
# the same name as a link in that directory, lnk will fail from a link check.

Why not use mpc?

Ugly as crap, and possibly not the best way to do it, but it gives me the output of iwlist scan as quality - essid - encryption status.
I know, I know, I could install a proper wireless manager too but ...meh

#!/bin/sh
iwlist wlan0 scanning|egrep "Quality|ESSID|Encryption"|sed "N;N;s/.*Quality=\\([0-9/]*\\).*\n.*\\(Encryption key:[a-z]\\{2,3\\}\\).*\n.*ESSID:\\(\".*\"\\)/\\1 - \\3 - \\2/"|sort -gr

Define a word using the dict.org server.

function define ()
{
    dictionary="english"
    [[ "$2" != "" ]] && dictionary=$2
    echo "DEFINE $dictionary $1\nQUIT" | netcat dict.org 2628
}

Small improvement to my pkill frontend, now it is more appropriate for killing multiple processes and the interface is simpler. Send SIGKILL by trying to send SIGTERM for the second time.

#! /bin/bash
IFS="
"
hist=0
while true; do
processes=$(ps -o pid,cmd,etime,time,pcpu,pmem,ppid,euser -p $(pgrep "$1") 2>/dev/null) || exit
echo "   "$(echo "$processes" | head -n 1)
processes=$(echo "$processes" | tail -n +2)
    select process in $processes; do
    pid=$(echo $process | sed 's/^ *\([0-9]*\).*$/\1/')
    [ -z "$pid" ] && exit
    if echo "$hist" | grep -qx $pid; then
        echo SIGKILL $pid
        kill -9 $pid
    else
        echo SIGTERM $pid
        kill $pid
    fi
    hist=$hist$'\n'$pid
    break
    done
done

edit: added -x for grep

I have a script that does the same with googles define feature

dictionary(){ 
echo Definitions of  $1 on the Web:
echo " "
curl -s -A 'Mozilla/4.0'  'http://www.google.co.uk/search?q=define%3A+'$1  | html2text -ascii -nobs -style compact -width 500 | grep "*" | head -n 5
}
