Re: Post your handy self made command line utilities

lol, love the hypnotoad

This script I got the idea from VictorVictorVictor's plasma config backup script.  I found too that at times the plasma configurations go bad at times.  This backups and also restores from a provided list.  lolilolicon helped me learn how to create the list:

plasmabak b|r

#!/bin/bash
# plasmabak - backup and restore local plasma config

# text color variables
bldylw='\e[1;33m' # yellow
bldblu='\e[1;34m' # blue
bldred='\e[1;31m' # red
bldwht='\e[1;37m' # white
txtrst='\e[0m'    # text reset

backdir=/root/backup/kde4-plasma-rcs
userdir=/home/todd
plasmarcs=($(find "$userdir"/.kde4/share/config -type f -name "plasma*"))
bkpplasmarcs=($(find "$backdir" -type f -name "plasma*"))
date=$(date +%F)

# Display usage if full argument isn't given
if [[ -z "$@" ]]; then
  echo " ${0##*/} b|r - backup or restore plasma configurations"
  exit
fi

# Check if the directory exists and user has access to it
if [[ -n $(ls "$backdir" 2>&1 | grep denied) ]]; then
  echo -e "${bldred}*${txtrst} User doesn't have access to directory"
  exit
  else
  if [[ ! -d "$backdir" ]]; then
    mkdir "$backdir"
    echo -e "${bldblu}*${txtrst} KDE 4 plasma config backup directory doesn't exist.  Created."
  fi
fi

# Delete backups older than two months
if [[ -n "$(find "$backdir" -mtime +60)" ]]; then
  find "$backdir" -mtime +60 -exec rm {} \;
  echo -e "${bldblu}*${txtrst} Configurations older than two months deleted"
fi

case $1 in
  b | backup )  tar -czpf "$backdir"/plasmarcs-"$date".tar.gz ${plasmarcs[@]}
                echo "${bldblu}*${txtrst} plasma configurations backed up."
                ;;
  r | restore ) for((i=0;i<${#bkpplasmarcs[@]};i++)) ; do
                  echo -e " ${bldwht}${i}) ${bkpplasmarcs[$i]##*/}${txtrst}"
                done
                echo -n "Choose the plasma configuration to restore: "
                read restore
                selection="${bkpplasmarcs[$restore]}"
                tar -xvf "$selection" -C /
                echo -e " ${bldwht}*${txtrst} Restored plasma configs: ${bldwht}${bkpplasmarcs[$restore]##*/}${txtrst}"
                ;;
  * )           echo -e " ${bldwht}*${txtrst} Use 'plasmabak b' to backup and 'plasmabak r' to restore"

Looking back, some of these are in need of a rewrite.

Re: Post your handy self made command line utilities

Oh, I didn't know that this script exists. ;x
For me it was faster to write my own, than search for some solution like mkarchroot, but I'll get more information about it. Thanks Daenyth!

Re: Post your handy self made command line utilities

Below is just a small script I use to throw together what I call a "catalog" of my music, using the information from the MP3 tags.  It uses the eyeD3 module, so you'll need to install that (it's in the AUR though).  Basically it just compiles a formatted list of each song.  You could probably easily edit it to display just artists, etc., but I found this to be the most useful.  In case you're wondering why I would ever need this, I get tired of trying to list off a collection of artists if someone asks me what music I listen to, or something like that, so now I can just send them the list of songs.  I'm fairly certain I commented the script fairly well, and it should work fine for any linux-based machine (no idea about windows, since you'd have to install eyeD3).  Also, it makes a list of all your files in musicList.txt, so you can set the script to automatically delete it/skip that step if you'd like, but I find it useful to have around for debugging purposes.

*EDIT* Word of warning: The script isn't really complete, since it can't create the catalog of any kind of file besides mp3.  I don't know of a module for python that can read those tags, so for the time being it will find the files, but skip them in the catalog (all my music has been converted to mp3 anyway).

#/usr/bin/env python

Re: Post your handy self made command line utilities

Odd. Where are those errors coming from? Looks like it's the contents of your mpd.log file. Do you rotate it often? Any crashes lately? Try adding something and running mpc update.

Re: Post your handy self made command line utilities

I recently broke the default playlist size limit of mpd (16000?), and thought something was wrong with python-mpd or my netcat script, so thinking of the other mpd.db scripts in this thread I wrote a script to sort the database to an m3u playlist.

awk 'BEGIN {RS="key:"; FS="\n"} { i=0; while (i++<=NF) { if ( $i ~ /^file:/ ) { file=substr($i,7); }; if ($i ~ /^Album:/) {album=substr($i,8) }; if ( $i ~ /^Artist:/) {artist=substr($i,9) }; if ( $i ~ /^Track:/) { track=substr($i,8) }; if ( $i ~ /^Title:/) { title=substr($i,8) }; }; if ( file != "" ) { print track"\t"album"\t"file"\t"title }; };' ~/.mpd/mpd.db | sort -f -k3,3 | sort -f -s -k4,4 | sort -n -f -s -k1,1 | sort -f -s -k2,2 | cut -f 3 > $(date '+%Y-%M-%d').m3u

I don't sort by artist, but it should be easy to add. The sort pipes go from least significant to most (this works thanks to sort -s). In this case: [filename, title], track, album. The first field must be numeric (track) for sort to work numerically (i.e. you can't sort numerically on fields above 1 due to a coreutils bug). If you add an artist field note that the filename field repeats in cut -f 3.

Re: Post your handy self made command line utilities

A simple python script for checking and removing duplicate mp3 songs based on the id3 tag, artist and title. At the end it removes the duplicates leaving one copy. This is how I cleaned out 30GiB worth of music over the weekend

Make sure to change the path and trash directories. (i don't use a trash directory, but I wanted to check if this script wouldn't remove all my music files It uses pyid3lib from the repos. As far as I can tell, this worked for me, but this was written quickly so you might want to double check and send in some patches if you find something/ make it better

#!/usr/bin/python
import os
import pyid3lib
import shutil

path = "/home/tom/backup/siradio/"
trash = '/home/tom/trash/'
contents = os.listdir(path)

# table format
# path / artisttitle / marked for deletion
db = [None] * len( contents )
for i in range( len( contents ) ):
        tag = pyid3lib.tag( path + contents[i] )
        artisttitle = contents[i]
        # handle bad tags
        try:
                artisttitle = tag.artist + tag.title
        except:
                pass
        # fill table with contents
        db[i] = [contents[i], artisttitle, '']

for i in range( len( db ) ):
        for j in range( i + 1, len( db ) ):
                # check if artisttitle string is equal
                if db[i][1] == db[j][1]:
                        # mark for deletion
                        db[j][2] = 'd'

for i in range( len( db ) ):
        if db[i][2] == 'd':
                shutil.move( path + db[i][0], trash )

Re: Post your handy self made command line utilities

I normally use RCS to edit most files, but sometimes I just want a quick backup of a file.
This is in my .bashrc file.

bu () { cp $1 ~/Backups/${1}-`date +%Y%m%d%H%M`.backup ; }

Called with "bu somefile" it puts a timestamped copy of whatever file in my Backups directory.

Here is one I use to get directory sizes in my current directory

dirsize ()
{
du -shx * .[a-zA-Z0-9_]* 2> /dev/null | \
egrep '^ *[0-9.]*[MG]' | sort -n > /tmp/list
egrep '^ *[0-9.]*M' /tmp/list
egrep '^ *[0-9.]*G' /tmp/list
rm /tmp/list
}

I'm sure it could be tweaked a bit, but it does all I want it to
Not sure where I got that one, I did not write it.

This one greps by paragraph

grepp ()
{
perl -00ne "print if /$1/i" < $2
}

This one finds stuff in my history file

hs() {
history | grep ${1} | uniq --skip-fields=1 | sort -biz | uniq --skip-fields=2
}

This one makes using the bash shell easier for calculations

calc () { echo "scale=4; $1" | bc ; }

Someday I'll go into my whole .bashrc/.profile setups, but these are some of the things I thought some might find useful.

I think it is best to quote your variable here. Or else it will break if the filename has a space.

bu () { cp "$1" ~/Backups/"${1}"-`date +%Y%m%d%H%M`.backup ; }

Re: Post your handy self made command line utilities

One of the most helpful scripts I use is "forcemount"
It is used if you have a disk image including partition tables and stuff and just want to mount the first partition of it no matter what.
The script just tries to mount the image and if that doesn't work skips some bytes forward and tries again. Useful for mounting full disk dd images or some types of virtual machine images directly:

#!/bin/bash

if [ "$1" = "" ] || [ "$2" = "" ] ; then
        echo "Usage: $0 <file> <mountpoint>" >&2
        exit 1
fi

for (( i=0; $i < 10000; i=$i + 1 )); do
   mount -o loop,offset=$(($i*512)) $1 $2 2>/dev/null >/dev/null && break
done

Re: Post your handy self made command line utilities

My old packages checking script for conky like stopped working :S ah well, i threw together a new one in like a minute:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import os
import string

check="pacman -Quq"
pkgs=os.popen(check)

count=0

for i in pkgs:
  count=count+1

if count==0:
  print "0 new packages"
elif count==1:
  print "1 new package"
else:
  print str(count)+" new packages"

Re: Post your handy self made command line utilities

Not a script per say but a couple of useful aliases. Works like a very simple pushd and popd in bash. Only difference is that this one only works with one directory and it is global across all terminals.

I often have a project in a directory and open a couple of urxvts, one for coding, one for building. I simply cd into the project dir, do a pud and then in the other urxvt do a pod. Saves typing.

alias pud='pwd > ~/.dir'       #push directory
alias pod='cd $( cat ~/.dir )' #pop directory

I know there has to be a better way to do this but this is nice and simple and works for me.
