Re: Post your handy self made command line utilities

I prefer mpd.

sub mpdrand {
    my @songs = $mpd->collection->all_pathes;
    my @randoms = shuffle(@songs);
    $mpd->playlist->clear;
    $mpd->playlist->add(@randoms[0..29]);
    $mpd->random(1);
    $mpd->repeat(1);
    $mpd->play;
}

Re: Post your handy self made command line utilities

I don't know if you'll call it a utility. But its pretty helpful at times (at least for me).

In ~/.bashrc

smiley() {
    val=$?
    if [ "$val" = "0" ]
    then
        echo ":-)"
    else
        echo ":-("
    fi
}

And

PS1='[\u@\h \W $(smiley)] \$ '

And the terminal window looks something like this.

[mango@arch ~ :-)] $ man woman
No manual entry for woman
[mango@arch ~ :-(] $

Re: Post your handy self made command line utilities

Speaking of "man"........ I wanted a quick way to view manpages and have the window close when I'm done, so.. here it is; a poorly scripted manpage selector. Done before, yeah. I originally wanted one through ratpoison and it worked for the most part but I couldn't figured out how to get tab-completion. I'll figure it out later. In the meantime, this has a small lag when first ran since I avoided a cache file. Knicked some of this from Ion, which is one feature I missed when moving away from it. Tried keeping it short without all the "for's" and "if=:'s". du works.

#!/bin/sh
# Simple manpage selector with dmenu.

DMENU="dmenu -b -fn -*-fixed-medium-r-normal-*-9 -nb #000 -nf #625873 -sb #a488d9 -sf #000"

CACHE=`du -a "/usr/share/man"|sed 's:^.*/\([^/]*\.[0-9].*\)$:\1:p; d'|\
sed 's:^\(.*\)\.[0-9].*$:\1:p; d'|sort -d|awk ' !x[$0]--' `

CHOICE=`echo -e "$CACHE" | $DMENU ${1+"$@"}` && exec urxvt -e man $CHOICE

Re: Post your handy self made command line utilities

BASH function that when run from a Linux source tree builds a User Mode Linux kernel and modules using the default config.
Installs UML to ~/bin, modules to ~/bin/uml_modules for later copying to root fs.

function uml {
    [ -e README ] || return
    [[ $( head -n 1 README ) =~ Linux\ kernel\ release\ 2.6.xx ]] || return
    make mrproper
    make mrproper ARCH=um
    make defconfig ARCH=um
    make -j 3 ARCH=um
    cp linux $HOME/bin/linux-$( ./linux --version )
    make modules_install INSTALL_MOD_PATH=$HOME/bin/uml_modules ARCH=um

Re: Post your handy self made command line utilities

I actually wrote these few tiny functions after a bit of an annoyance writing another script, so I present as is:

isset(){
  eval "test \"\${$1+set}\" = 'set'"
  return $?
}
ar_pop(){
  eval "TMP=\"\${${1}[\${#${1}[@]}-1]}\""
  eval "unset ${1}[\${#${1}[@]}-1]"
  echo $TMP
}
ar_push(){
  eval "${1}[\${#${1}[*]}]=\"$2\""
}
isEmpty(){
  return $( head -c 1 "$1" | wc -c )
}

And some sample usage:

## First, isset:
isset1=test
isset2=''
isset3=0
unset isset4
for i in isset{1..4}; do
  echo testing $i
  isset $i && echo SET || echo UNSET
done

## Then the array functionality

ARTEST=()
ar_push ARTEST 'Test 1'
ar_push ARTEST 'Test 2'
echo $(ar_pop ARTEST)
ar_push 'Test 3'
echo ${ARTEST[@]}

## And finally the isEmpty check.
FILE=$(mktemp)
isEmpty $FILE && echo made empty || echo made with content.
echo testing 123 > $FILE
isEmpty $FILE && echo still empty || echo now with content.
> $FILE
isEmpty $FILE && echo empty again || echo still got content.
rm $FILE

Re: Post your handy self made command line utilities

Here's something that a friend of mine has made. The idea was actually taken from an existing script. This is to test which DNS service resolves faster (not sure if I got the terms correctly). The test made me transfer to Google's public DNS. More info here: http://xmodx.com/google-dns-vs-opendns/

#!/bin/sh
isp=$(dig +noall +stats 2>&1 | awk '$2~/^SERVER:$/{split($3,dnsip,"#");print dnsip[1]}');
m="-------------------------------------------------------------------------------";
s="                                                                               ";
h="+${m:0:25}+${m:0:12}+${m:0:12}+${m:0:12}+${m:0:12}+${m:0:12}+";
header=("Domain${s:0:23}" "Your ISP${s:0:10}" "Google${s:0:10}" "4.2.2.2${s:0:10}" "OpenDNS${s:0:10}" "DNS Adv.${s:0:10}");
echo "${h}";
echo "| ${header[0]:0:23} | ${header[1]:0:10} | ${header[2]:0:10} | ${header[3]:0:10} | ${header[4]:0:10} | ${header[5]:0:10} |";
echo "${h}";
for i in "xmodx.com" "yahoo.com" "google.com";
do
  ii="${i}${s:23}";
  echo -ne "| ${ii:0:23} |";
  for j in "${isp}"  "8.8.8.8"  "4.2.2.2" "208.67.222.222" "156.154.70.1";
  do
    r="${s:10}$(dig +noall +stats +time=9 @${j} ${i} 2>&1 | awk '$2~/^Query$/{print $4" "$5}')";
    echo -ne " ${r:${#r}-10} |";
  done
  echo -e "\n${h}";
done

Re: Post your handy self made command line utilities

A small screen starter script for windows friends who wants to use irssi Well it became handy and started to use it myself, too. One problem needs some advise, the power-detach. It just kills (logout) the script, but not the login. Howto duplicate the logout signal or otherwise catch it and then in the script forward it to shell? Screen does not like to be backgrounded from the script with &.

#!/bin/bash
#

ME=$(whoami)
STATUS="0"

# Use screen ID of $1
if [[ $1 != "" ]]; then
   SCREEN_ID="$1"
   # special conf file for this ID
   if [ -f /home/$ME/.screenrc."$1" ];then
      SCREENRC="/home/$ME/.screenrc."$1""
   else
      SCREENRC="/home/$ME/.screenrc"
   fi
# Use the default screen ID
else
   SCREENRC="/home/$ME/.screenrc.irkki"
   SCREEN_ID="irkki"
   if [ ! -f /home/$ME/.screenrc.irkki ];then
      echo "Create ~/.screenrc.irkki from .screenrc first"
      exit 1
   fi
fi

# screen ID was not found
screen -ls | sed -ne 's/\t// p' | grep -qi "\.$SCREEN_ID" || STATUS="1"
# screen ID dead, restart
screen -ls | sed -ne 's/\t// p' | grep -i "\.$SCREEN_ID" | grep -qi "(dead.*\?)" && STATUS="2"
# attach the old one
screen -ls | sed -ne 's/\t// p' | grep -i "\.$SCREEN_ID" | grep -qi -e "(detached" -e "(attached" && STATUS="3"

if [[ $STATUS == "1" ]]; then
   screen -dmS "$SCREEN_ID" -c "$SCREENRC"
   screen -raAdS "$SCREEN_ID"
elif [[ $STATUS == "2" ]]; then
   screen -wipe "$SCREEN_ID"
   screen -dmS "$SCREEN_ID" -c "$SCREENRC"
   screen -raAdS "$SCREEN_ID"
elif [[ $STATUS == "3" ]]; then
   screen -raAdS "$SCREEN_ID"
elif [[ $STATUS == "0" ]]; then
   echo "I am confused...."
   echo ""
   screen -list
fi

exit 0

Automatic screenshot uploader with bbcode generation output for posting screenshots on the forum.

    echo "File upload Failed!"

the myscrot.pl line can be replaced with whatever command-line scrot app you have, as long as it outputs in the form `date +%b`scrot.png

The volume and pacman scripts are useful if you bind them to multimedia keys on you keyboard.

Re: Post your handy self made command line utilities

EDIT: See the responses from other people below for better ways to implement this.

I just finished making "move-follow" and "copy-follow" commands. I've always wanted them, but never got around to making them.

Move-follow ("mvf") will move files like the regular mv command, then change directory to the directory that you just moved the files to. So doing:

mvf *.jpg ~/Desktop

would be equivalent to:

mv *.jpg ~/Desktop
cd ~/Desktop

I'm sure you can figure out what "cpf" does.

Note: I am a professional programmer, but I am not a professional BASH programmer. Feel free to clean these up if you want.

# Move-follow command
function mvf {

  # If the move command fails
  # then just quit.
  if ! mv "$@"; then
    return
  fi

  # Go to the directory where you
  # moved the file to.
  eval last_arg=\$$#
  if [ -d "$last_arg" ]; then
    # The final parameter was a directory.
    cd "$last_arg"
  elif [ -e "$last_arg" ]; then
    # The final parameter was a file.
    # Get the directory that the file is in.
    eval last_arg=${last_arg%/*}
    cd "$last_arg"
  fi

  pwd
}

# Copy-follow command
# (See the move-follow command)
function cpf {

  if ! cp "$@"; then
    return
  fi

  eval last_arg=\$$#
  if [ -d "$last_arg" ]; then
    cd "$last_arg"
  elif [ -e "$last_arg" ]; then
    eval last_arg=${last_arg%/*}
    cd "$last_arg"
  fi

  pwd
}

Re: Post your handy self made command line utilities

I put this in /etc/cron.weekly to automatically update my system clock once per week. Install "rdate" from the AUR. Use a time server closer to your location - this one for Canada:

#!/bin/sh
#
rdate -s time.nrc.ca && hwclock -w

@drcouzelis: you should surround $@ in double quotes or it won't work with filenames with spaces.

    cd "$last_arg"
  fi

  pwd
}

nice idea!

hope you don't mind i cleaned it up a bit:

goto() { [ -d "$1" ] && cd "$1" || cd "$(dirname "$1")"; }

cpf() { cp "$@" && goto "$_"; }

mvf() { mv "$@" && goto "$_"; }

not extensively tested but i think it works.

Re: Post your handy self made command line utilities

Cleaner, but requires zsh:

mvf ()
{             
  if [[ -d $*[-1] ]]; then
    mv $* && cd $*[-1]
  elif [[ -d ${*[-1]%/*} ]]; then
    mv $* && cd ${*[-1]%/*}
  fi
}

edit: brisbin beat me to it didn't think of dirname and $_.

Re: Post your handy self made command line utilities

nice idea!

hope you don't mind i cleaned it up a bit:

goto() { [ -d "$1" ] && cd "$1" || cd "$(dirname "$1")"; }

cpf() { cp "$@" && goto "$_"; }

mvf() { mv "$@" && goto "$_"; }

not extensively tested but i think it works.

Nice! Great idea drcouzelis.

Re: Post your handy self made command line utilities

Very nice cleanup brisbin! I've wanted this for some time. I'll add it to my bashrc later

Re: Post your handy self made command line utilities

no very handy but could give someone a few lafs

just wrote this because i was bored, another small prank script

it types a random word as if you the user typed them you need a word list (can be a complete dictionary or just a list of swear words). you can find them online. just needs to be a plain text file with each word on its own line.

it requires xdotool

#!/bin/bash
while true; do
maxdelay=3000
mindelay=60
sleeptime=$(seq $mindelay $maxdelay| sort -R | head -n 1) 
wordlist=~/wordlist.txt
word1=$(sort -R "$wordlist" | head -n 1)
xdotool type " "$word1
echo waiting for $sleeptime seconds ##just in during testing, not needed.
sleep $sleeptime
done

Is there some reason you are continually randomly sorting the whole list, then picking a random entry, as opposed to something more like:

maxdelay=3000
mindelay=60
wordlist=~/wordlist.txt
wlen=$(wc -l "$wordlist")

rand(){
  min=$1
  max=$2
  [ $min = $max ] && echo $min && return 0
  echo $[ $RANDOM % ( $max - $min + 1 ) + $min ]
}

while true; do
  sleeptime=$(rand $mindelay $maxdelay)
  word1=$(head -n $(rand 1 $wlen) "$wordlist" | tail -n 1)
  xdotool type " ${word1}"
  sleep ${sleeptime}
done

This should reduce the load by quite a bit, as well as saving some time reading the whole file in every time it runs if you only need half the file on average.

Re: Post your handy self made command line utilities

With a little help from nice people on #archlinux (especially 'rson') I managed to sort my images into folders based on size:

#!/bin/bash

cd ~/wallpapers
for image in *;
do 
    dims=$(feh -ls $image | cut -f3,4 --output-delimiter=x | sed 's/WIDTHxHEIGHT//')
    echo $dims
    mkdir $dims &> /dev/null
    mv $image $dims
done

Re: Post your handy self made command line utilities

Thank you! I was looking for something like that!

I'll modify it to sort by aspect ratio instead of strict dims though.

Re: Post your handy self made command line utilities

there are probably alot better ways of doing this...

This script  gets called by rtorrent when a download is complete, moves the downloads to the corect folder, then emails me to tell me.

if echo "$1" | grep -q '.iso$'; then

        mv "/media/torrents/downloading/$1" /media/torrents/DiskImages/ 
    folder=/media/torrents/DiskImages

elif echo "$1" | grep -q 'Chuck'; then

    season=`ls /media/torrents/tv/Chuck/| tail -n 1`
    mv "/media/torrents/downloading/$1" /media/torrents/tv/Chuck/$season/
        folder=/media/torrents/Chuck/$season/

elif echo "$1" | grep -q '24.S'; then

    season=`ls /media/torrents/tv/24/| tail -n 1`
        mv "/media/torrents/downloading/$1" /media/torrents/tv/24/$season/
    folder=$/media/torrents/24/$season/

elif echo "$1" | grep -q 'House'; then

        season=`ls /media/torrents/tv/House/| tail -n 1`
        mv "/media/torrents/downloading/$1" /media/torrents/tv/House/$season/
    folder=/media/torrents/tv/House/$season/

elif echo "$1" | grep -q 'South.Park'; then

        season=`ls /media/torrents/tv/Southpark/| tail -n 1`
        mv "/media/torrents/downloading/$1" /media/torrents/tv/Southpark/$season/
    folder=/media/torrents/tv/Southpark/$season/
elif echo "$1" | grep -q 'Two.and.a.Half.Men'; then

        season=`ls /media/torrents/tv/TwoAndAHalfMen/| tail -n 1`
        mv "/media/torrents/downloading/$1" /media/torrents/tv/TwoAndAHalfMen/$season/
    folder=/media/torrents/tv/TwoAndAHalfMen/$season/

elif echo "$1" | grep -q 'Lie.to.me'; then

        season=`ls /media/torrents/tv/LieToMe/| tail -n 1`
        mv "/media/torrents/downloading/$1" /media/torrents/tv/LieToMe/$season/
    folder=/media/torrents/tv/LieToMe/$season/

elif echo "$1" | grep -q 'FlashForward'; then

        season=`ls /media/torrents/tv/FlashForward/| tail -n 1`

        mv "/media/torrents/downloading/$1" /media/torrents/tv/NCIS-LA/$season/
        folder=/media/torrents/tv/NCIA-LA/$season/

elif echo "$1" | grep -q 'NCIS'; then

        season=`ls /media/torrents/tv/NCIS/| tail -n 1`
        mv "/media/torrents/downloading/$1" /media/torrents/tv/NCIS/$season/
        folder=/media/torrents/tv/NCIS/$season/

        season=`ls /media/torrents/tv/TheBigBangTheory/| tail -n 1`
        mv "/media/torrents/downloading/$1" /media/torrents/tv/TheBigBangTheory/$season/
        folder=/media/torrents/tv/Scrubs/$season/

else
    mv "/media/torrents/downloading/$1" /media/torrents/finished

fi 


echo -e "$(date) : $1 - Download completed. \n\nfile has been moved to $folder" | mail -s "[rtorrent] - Download completed : $1" myemail@address.com

any pointers welcome

Re: Post your handy self made command line utilities

Use the "case" statement. It should make that *much* more readable. Also inside the case block I'd set a variable for the target dir and then move the mv call outside so you only call mv once instead of having it in every block.

eg:

case $1 in
    *.iso) target=/media/torrents/DiskImages ;;
    *Chuck*) target="/media/torrents/Chuck/$(ls /media/torrents/tv/Chuck/| tail -n 1)" ;;
...
esac
mv "/media/torrents/downloading/$1" "$target"
