Lol you are correct, I have no idea why I came up with that snake of a code. Was kinda tired when I wrote it I guess

Can you give a complete list of "LOC CODE" for easy reference? I can't seem to find one instead of the one-by-one lookup method.

I just went to http://www.accuweather.com/rss-center.asp , entered my city, and copied the code for it smile

Re: Post your handy self made command line utilities

I use this script to track which arch posts I have seen as well output
to a file any unique posts.

I use vim in urxvt with the mark-and-yank perl plugin to open urls.  I
read from bottom to top.  I either open the url and delete the line or
delete the line.

I have all my rss feeds to go email which I read with mutt.  I decided I
would like to process this file when I read my email.  I do this by
symlinking a mail file to the output file.  One needs to leave the mail
headers at the top of the file, if they wish to have this feature:

    Date: Sun, 04 Oct 2009 14:36:58 -0400
    From: Steve
    To: Steve
    Subject: ArchLinux Forums

When the script writes to the file it will bump the timestamp to the
current time.  It does not mark the file as new.  I edit the file in
mutt with this key binding:

    macro generic,index,pager   E "<shell-escape>vim + /PATH/TO/FILE<enter>" "unique archlinux forum posts"

If one does not wish to have the output file managed with their email
client then comment out the 'cat "$af" line.

I'm new to bash scripts so feedback is welcomed.  Here is the script:

#!/bin/bash

script=${0##*/}
af=$HOME/doc/af
aflist=$HOME/doc/aflist
aftmp=$HOME/tmp/af.tmp

usage() {

    cat << EOF

    usage: $script

    This script is used to download the most recent archlinux.org forum posts.
    Forum posts being the posts' title along with its URL. It has the ability
    to track which posts the user has viewed and store the unread forum posts
    in a file.

EOF
}

if [[ "$#" -ne "0" ]]; then
    usage
    exit 1
fi

ps a | \
    grep -q "[0-9] vim /root/doc/af" && exit 0

wget -q -O - http://bbs.archlinux.org/search.php?action=show_24h | \
    grep -v stickytext | \
    grep "viewtopic.php?id=" | \
    awk -F'"' '{print $2 $3}' | \
    sed -e 's@</a> <span class=@@' | \
    sed -e 's@viewtopic.php?id=@@' | \
    awk -F'>' '{printf("%06d>%s", $1, $2 "\n")}' >> "$aflist"

sort -r "$aflist" | \
    uniq -w 6 > "$aftmp"

mv "$aftmp" "$aflist"

grep -v '^[0-9]*#' "$aflist" | \
    sed 's/0*//' | \
    awk -F'>' '{print "http://bbs.archlinux.org/viewtopic.php?id=" $1 " " $2}' >> "$af"

# vim:set sw=2 ts=2 et:

My latest mpd script, called m,which is almost like a forth-ish DSL for interacting with a mpd at the protocol level, instead of via mpc. The main idea is to query mpd directly, apply some transformations to the stream, and possibly pipe the result back again. First of all you have a bunch of words defined in the script, ignore those for one second. The words not defined are sent straight to the mpd server ("m pause" would pause the player). Then you have "m", invoked without any arguments, acts as a sink for protocol commands. ("echo pause | m" would also pause the player). The rest of the words are either meant as pipe transformers or shortcuts for complicated ones.

For instance, say you want to add all the songs in your music library that contain the words 'sabbath' and 'reality', you'd type

m listall | m get file | m filter sabbath reality | m add | m

Now, imagine that you find that it's useful to be able to quickly add things to your playlist in that manner, you can easily define it as a new word by adding the line

 "qadd")  shift; $0 listall | $0 get file | $0 filter $* | $0 add | $0 ;;

to your script and hey presto; you are now able to quickly add new stuff by issuing "m qadd foo bar". This is obviously a fairly idiosyncratic way of interacting with mpd, so it might take some experimenting to get used to.

@brisbin,
Look, I think you should separate artist and album with something more unique ... The advantage is that if you want to search other sites which treat artist and album separately(e.g. last.fm uses the format of .../artist/album).

Yeah, i doubt i'll be using any other search sites anytime soon, so leaving it w/o the separator just makes things simpler IMHO.

As for a wider format support, you can try audiotag, it's a simple perl script and it's in AUR.

I just tried to install this but it needs atomicparsley which fails to build for me... haven't looked into it further though.

Another thought: Why not just use mpd.db to produce the list?

i actually didn't know that the mpd.db was a plain text file that i could parse like that.  certainly makes things easier... if one were using mpd.  as it is now, my script is media player agnostic and i think i might want to keep it like that.

thanks for the comments!

atomicparsley is not necessary. Just download from this mirror, extract it and put the perl script in $PATH. That's all. smile

Yeah, that's why I said it's an 'alternative' way. Actually, if you think about it, you can make your list formatting to mimic (a stripped-down) mpd.db, so non-mpd users and mpd users can use the same parsing method while mpd users gets extra speed-up.

After all, nice script brisbin.

Re: Post your handy self made command line utilities

Command line calculator.  I find it a little easier to type in the terminal than doing mouse-clicks in the gui.

#!/bin/sh
# calc - command line calculator

# display usage if full argument isn't given
if [[ -z $@ ]]; then
  echo ' calc "<input>" <*decimals> - command line calculator (-h for example)'
  exit 1
fi

# decimal to be carried out to, uses default (4) unless value is given
if [[ -z $2 ]]; then
  decimals=4; else
  decimals=$2
fi

case $1 in
  -h )  echo ' calc "5*((2^3*2)/1.352)"'
        echo ' calc "p=10; n=9; p*n+10"' ;;
  *  )  echo "scale=$decimals;$1" | bc
esac

Re: Post your handy self made command line utilities

@brisbin33 -- hey, is the fix for filenames with spaces still in the works? I'd love to give this a whirl, but it totally choked on my collection.

I also unsuccessfully tried to get atomicparsely working awhile ago when I was trying another tagger. No luck sad

Thanks for your work!

Re: Post your handy self made command line utilities

For the bored who watch American TV, this script tells you what should be available for download today (so what aired yesterday) using eztv.it database (you can also run it with arguments like today or specific days)

#! /bin/bash
day=$(LANG=en_US.utf8 date +%A -d "${1:-yesterday}")
echo $day
echo '--------'
curl -s 'http://eztv.it/showlist/' | grep -F -B1 "$day" | grep -F '/shows/' | sed 's/^[[:blank:]]*//;s/<[^>]*>//g'

Dummypkg: Let pacman know if a program has been installed manually from source: (kernel and nvidia driver (libgl) in my case tongue)

This is a nice package. I use it for TeX Live (since I would rather use the TeX Live net installer).

However, Dummypkg lacks a solution for pure release number changes (i.e. release 1 to 2 without an upstream upgrade). I can tell from the source that it is set to 1 by default.

Is it possible to set this variable other than editing the source of Dummypkg?

Re: Post your handy self made command line utilities

Hi

I am using this script to access my Gmail accounts and give me an audio information about how many messages are available.  It was copied from Ubuntu forum as written at the script header.  I've tried to implement it in order to access archlinux.us mail but not succeeded so far.  I was told to try curl instead of wget but considering the lack of knowledge on script program I am puzzled on this issue too.

Nothing big, but handy:

    ossmix vmix0-outvol $1
else
    ossmix $(ossmix|grep $1|cut -d\  -f1) $2
fi

$vol mpd 25


I need a sorted list of all random numbers, so that I can retrieve a suitable one later with a binary search instead of having to iterate through the generation process every time.

Re: Post your handy self made command line utilities

hey guys here is a first big script of mine that I have been developing for some time.
Its not written from scratch, I've edited & added some code from other scripts.
It consists mostly of brisbin33's burn script & disk blanking from Gen2ly's burniso script.
Rest is added by me.

Since it's my first script It's not as much efficient & might be some functions are available other way.

hey guys here is a first big script of mine that I have been developing for some time.
Its not written from scratch, I've edited & added some code from other scripts.
It consists mostly of brisbin33's burn script & disk blanking from Gen2ly's burniso script.
Rest is added by me.

Since it's my first script It's not as much efficient & might be some functions are available other way.

please comment

#!/bin/zsh

# colors {{{

# }}}

You could use the color module instead.

autoload colors; colors;
echo $fg[red]$bg[blue]red on blue

yep, I'll be using this,
that's why open-source is so good coz you can improve your code much quickly...

Re: Post your handy self made command line utilities

something just for fun.  the mpd database is surprisingly parsable... need to think of some other nifty stats to calculate...

┌─[ 12:20 ][ blue:~ ]
└─> cat .bin/mpdstats
#!/bin/bash
#
# pbrisbin 2009

###

database="$HOME/.mpd/mpd.db"

LC_ALL="C"

number_of() {
  local N=$(grep "$1" "$database" | sort | uniq | wc -l)
  echo $N
}

most_from() {
  local most=$(grep "$1" "$database" | sort | uniq -c | sort -r | head -1 | cut -d ':' -f 2-)
  echo $most
}

echo
echo "tracks  : $(number_of '^Title: ')"
echo "artists : $(number_of '^Artist: ')"
echo "albums  : $(number_of '^Album: ')"
echo
echo "most from artist : $(most_from '^Artist: ')"
echo "most from year   : $(most_from '^Date: ')"

Yes, the MPD database format is great.

Re: Post your handy self made command line utilities

Two little scripts:

1. shellpodder_mpd : A simple podcast client for mpd

#!/bin/sh
#Put your favourite podcast links into pod.conf (one per line)
rm -f playlist.pod
while read podcast
    do
    file=$(wget -q $podcast -O - | tr '\r' '\n' | tr \' \" | sed -n 's/.*url="\([^"]*\)".*/\1/p')
    for url in $file
        do
        echo $url >> playlist.pod
        done
    done < pod.conf
mpc crop
cat playlist.pod | awk '!x[$0]++'  | mpc add
mpc play

2.  conv_to_ogg_sansa_clip: Convert music from my flac collection
to ogg and apply crossfeed (with bs2bstream) for my portable audio player.

#!/bin/zsh

for f in **/*.flac 
do 
    outf=${f%.flac}.ogg
    eval "$(
               metaflac "$f" --show-tag=ARTIST \
                   --show-tag=TITLE \
                   --show-tag=ALBUM \
                   --show-tag=GENRE \
                   --show-tag=TRACKNUMBER \
                   --show-tag=DATE | sed 's/=\(.*\)/="\1"/'
    )"

    ARTIST=${ARTIST:=$artist}
    ARTIST=${ARTIST:=$Artist}
    TITLE=${TITLE:=$title}
    TITLE=${TITLE:=$Title}
    ALBUM=${ALBUM:=$album}
    ALBUM=${ALBUM:=$Album}
    GENRE=${GENRE:=$genre}
    GENRE=${GENRE:=$Genre}
    TRACKNUMBER=${TRACKNUMBER:=$tracknumber}
    TRACKNUMBER=${TRACKNUMBER:=$Tracknumber}
    DATE=${DATE:=$date}
    DATE=${DATE:=$Date}

    flac -s -d -c $f | bs2bstream -l 30 700| \
    oggenc -q 3 -r - -o /mnt/MUSIC/${PWD##*/}/$outf -a $ARTIST -t $TITLE -l $ALBUM -G "${GENRE:-non}" -N $TRACKNUMBER -d ${DATE:-2009}

#    echo $ARTIST $TITLE $ALBUM $GENRE $TRACKNUMBER $DATE

Re: Post your handy self made command line utilities

seek

Uses find for quick searches.

seek top         # find . -iname "*top*"
seek d top /etc  # find /etc -type d -iname "*top*"
seek f top       # find . -type f -iname "*top*"

Think I already saw something like this on this thread but I was too lazy to find it.

#!/bin/bash
# seek - search for name of files/folder(s) recursively in a directory

# display usage if full argument isn't given
if [[ -z "$@" ]]; then
  echo " ${0##*/} <*d,f> <pattern> <*location>"
  echo "   Search directory for file of folder match (*optional)"
  echo "   Example: 'seek d top /home/user'.  Output: '/home/user/Desktop...'"
  exit
fi

case $1 in
  d ) if [ -z "$3" ]; then
        find .    -type d -iname "*$2*"
        else
        find "$3" -type d -iname "*$2*"
      fi
      ;;
  f ) if [ -z "$3" ]; then
        find .    -type f -iname "*$2*"
        else
        find "$3" -type f -iname "*$2*"
      fi
      ;;
  * ) if [ -z "$2" ]; then
        find .    -iname "*$1*"
        else
        find "$2" -iname "*$1*"
      fi
      ;;
esac
