Re: Post your handy self made command line utilities

all these are nothing special, but they work fine for what i need:

toggles the mute status of mpd, have this tied to the mute key on my keyboard.

#!/bin/sh

if mpc | tail -n 1 | grep "volume:  0%" > /dev/null
then
 mpc volume +70
else
 mpc volume -100
 fi

checks if mpd is running, if it is not running then it runs it , and plays. if it is running it plays or pauses the music, i have this tied to the play/pause key on my pc.

#!/bin/sh
if pidof mpd | grep [0-9] > /dev/null
then
 mpc toggle  >/dev/null 2>&1
else
 mpd  >/dev/null 2>&1
 mpc play  >/dev/null 2>&1
 fi

this one displays the current stats of any torrent flux downloads, i use this through conky.

#!/bin/dash
dir=/media/downloads ## replace with torrentflux download dir
cutno=26 #Specifies the number of characters to show in the title name, usefull to stop
host=http://192.168.1.99/torrentflux

curl -c .tf_cookie -d username=$user -d iamhim=$pass $host/login.php >/dev/null 2>&1
curl -H "Expect:" -b .tf_cookie $host/index.php  >/dev/null 2>&1 > .torrentstats.tmp

echo Free Space `cat .torrentstats.tmp | grep -i '<strong' | tail -n 2| head -n 1 | cut -f3 -d'>' | cut -f1 -d'<';`

cd $dir/.torrents
echo Transfers: `ls *.stat  | wc -l` ##counts the amount transfers 
echo " "
for file in *.stat; do
size=`cat $file | tail -n 1;`
echo $file | cut -f1 -d'.' | cut -c 1-$cutno | tr '_' ' ' | tr -d '[{}(),\!]' | tr -d "\'" | tr '[a-z]' '[A-Z]'; ## displays torrent names, in upper case, without any puncuation 
echo `cat $file | head -n 3 | tail -n 1 | tr '[a-z]' '[A-Z]';`  : `cat $file | head -n 2 | tail -n 1;`% ## displays the status of the torrent
echo RX speed: `cat $file |  head -n 4 | tail -n 1;`  ##displays the current download speed per torrent 
echo TX speed: `cat $file |  head -n 5 | tail -n 1;` ##displays the current upload speed per torrent 
echo size: `expr $size / 1048576` MB ##displays the file size 
echo Seeds: `cat $file |  head -n 7 | tail -n 1 | cut -f1 -d'+';` ##displays the amount of seeds 
echo Peers: `cat $file |  head -n 8 | tail -n 1 ;` ##displays the amount of peers
echo " "
done
rm .torrentstats.tmp

this downloads the latest observation feed from bbc weather, then it prints out a bit of info. if you want to use this your self, you will have to change the link to the rss feed for your town, currently its set for london, also this is used with conky.

curl http://feeds.bbc.co.uk/weather/feeds/rss/obs/world/0008.xml  >/dev/null 2>&1 > .weatherfeedrs
echo Temperature:     `cat .weatherfeedrs | grep "Temperature"| cut -f2 -d' ' | tr '&#xB0' ' ' | cut -c 1-4`C
echo Wind Direction:  `cat .weatherfeedrs| grep "Temperature"| cut -f6 -d' ' | tr -d ','`
echo Wind Speed:      `cat .weatherfeedrs | grep "Temperature"| cut -f9 -d' '` mph
echo Humidity         `cat .weatherfeedrs | grep "Temperature"| cut -f13 -d' ' | tr '&#xB0' ' ' | cut -c 1-3`%
echo pressure `cat .weatherfeedrs | grep "Temperature"| cut -f15 -d' '` `cat .weatherfeedrs | grep "Temperature"| cut -f16 -d' '`
echo Visability:      `cat .weatherfeedrs | grep "Temperature"| cut -f7 -d':'| cut -c2-20`
rm .weatherfeedrs

becase all that does is play or pause the music, rather thun muting or un muting it.

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

Re: Post your handy self made command line utilities

implementing "join" in bash (python's join, php's implode, etc.).

NOTE: the $ means "type what follows at your terminal prompt" (some people thinks that the $ is part of the command).

    $ list_join() { 
        local OLDIFS=$IFS
        IFS=${1:?"Missing separator"}; shift
        echo "$*"
        IFS=$OLDIFS
    }

    $ list_join : one two three
    one:two:three

it only works for single characters, so this won't work as expected:

    $ list_join ', ' one two three
    one,two,three

tongue

also notice that you need to pass the list expanded (hence the name "list_join") so if you have an array you do:

    $ myarray=(one two three)
    
    $ list_join : "${myarray[@]}"
    one:two:three

this function is pretty handy to use with fgrep (grep -f); fgrep is faster than grep because it does not use regular expressions so unless you actually need a regexp it's best to use that instead of normal grep, fgrep also accepts several words to search at once and works like an OR operation (if you chain several greps you get an AND operation) the only problem is that fgrep expects you to separate the words by newlines -quite ugly- so you can use the function like this:

    $ fgrep "$(list_join $'\n' samus root)" /etc/group
    root::0:root
    bin::1:root,bin,daemon
    daemon::2:root,bin,daemon
    sys::3:root,bin
    adm::4:root,daemon
    disk::6:root
    wheel::10:root,samus
    log::19:root
    audio::92:samus
    optical::93:hal,samus
    storage:x:95:hal,samus

nice huh? smile

Re: Post your handy self made command line utilities

this is a little chunk of code to extract the next window ID in line, after the current window, that matches the name you pass to it.  requires wmctrl.

#!/bin/bash

ACTIVE=`xprop -root _NET_ACTIVE_WINDOW | awk '{print $5}' | sed 's/0x//' | tail -1`
FIRST=`wmctrl -l -x | grep $1 | awk '{print $1}' | head -1`
AFTER=`wmctrl -l -x | grep $1 | awk '{print $1}' | grep -A 1 $ACTIVE | head -2 | tail +2`
echo $AFTER $FIRST | awk '{print $1}'

then you bind a key (mine is W-x) to the command

bash -c "wmctrl -i -a `windowafter urxvt` || urxvt"

and pressing W-x cycles through all instances of urxvt, or opens a new one if none exists.  binding several (editor+urxvt+browser) = no more hunting with alt-tab trying to figure out if the right terminal was 2, 3, 4 windows ago.

also handy to bind W-C-x to force a new terminal open.

Re: Post your handy self made command line utilities

i remember seeing something like this in a blog but i couldn't find it so i wrote my own.  it's really simple but i can never remember which order to pass the arguments to ln -s so this script will take them in any order and still create the correct link based on which one already exists.

> cat Scripts/symlink
#!/bin/bash

if [ -e $1 ]; then
  if [ -e $2 ]; then
    echo both $1 and $2 exist. exiting.
    exit 1
  else
    ln -s $1 $2
  fi
else
  if [ -e $2 ]; then
    ln -s $2 $1
  else
    echo neither $1 nor $2 exist. exiting.
    exit 2
  fi
fi

exit 0

This cleared up for me when somebody reminded me its the same order as commands like mv and cp. In those commands you always mv|cp|ln oldfile newfile. Might help somebody someday.

that makes sense, somehow my brain always focuses on the word _to_

mv oldfile _to_ new file
cp oldfile _to_ new file
link something _to_ somethingelse.... nope

link _to_ something _from_ somethingelse...

Re: Post your handy self made command line utilities

Compare versions of packages in local repo with current versions in AUR.

I like to build packages from AUR manually and put them in a local repository.  This script basically compares versions of packages in a local repository with versions available from AUR.  It is designed to work with cron -- the script only produces output when more recent versions of packages are found on AUR -- which makes cron send an email with the output to my local mail account.  It doesn't have to be used with cron, of course. 

It is my first script in python so feel free to criticize smile

#!/usr/bin/env python

import re,os,urllib2,string
repo = 'myrepo' # put the name of your local repo here
aururl = 'http://aur.archlinux.org/rpc.php?type=info&arg='

def GetAURVersion(pkgname):
    aurinfo = urllib2.urlopen(aururl+pkgname).read()
    if "No result found" in aurinfo:
        return 0
    else:
        index1=string.find(aurinfo, "Version")
        index2=string.find(aurinfo, "Category")
        return aurinfo[index1+10:index2-3]

repopkgs=os.popen('pacman -Sl '+repo).readlines()
for repopkg in repopkgs:
    reporegex=re.compile(r' ')
    lpkgname=reporegex.split(repopkg)[1]
    aurversion = GetAURVersion(lpkgname)
    if aurversion == 0:
        continue
    else:
        lpkgversion=re.sub('\n','',reporegex.split(repopkg)[2])
        if aurversion > lpkgversion:
            print lpkgname+'\tlocal: '+lpkgversion+'\tAUR:'+aurversion

[randy@voodoo ~]$ lspt --help
Usage: lspt [options] [path]
    List permissions tree.

  Options:
    -d, --depth N          only traverse N levels up the tree

    -h, --help             display this usage message

Clean packages

I modified your code a bit:
First you get presented the packages one by one (Orphans first, then explicitly installed packages). Now you can select "yes" for certain packages. These are put into a file "/tmp/removeus" with some comments.
Then you can edit that file to remedy your choice again until you do something like:

sudo pacman -Rns $(grep -v "^#.*" /tmp/removeus | xargs)

on the generated list.

inspect-packages.sh

list_stuff () {
for pkg in $(pacman $1 | cut -d' ' -f1); do
  LC_ALL="C" pacman -Qi $pkg | grep --color=auto -E "(Name|Description|URL|Installed Size)"
  echo -ne "\ncandidate? "
  read doit
  case $doit in [yY]*)
    echo -e "\n\n" >> /tmp/removeus
    LC_ALL="C" pacman -Qi $pkg | grep -E "(Description|URL|Installed Size|Depends On)" | sed -r "s/(.*)/# \1/" >> /tmp/removeus
    echo $pkg >> /tmp/removeus
  esac
  echo -e "\n\n"
done
}

echo -e "\n\033[1m\033[1;33mOrphans...\n----------\n\033[0m"
list_stuff -Qdt

echo -e "\n\033[1m\033[1;33mExplicitly Installed...\n-----------------------\n\033[0m"
list_stuff -Qet

Re: Post your handy self made command line utilities

OK, everyone, I have news.

GREP CAN TAKE THE FILENAME TO SEARCH AS AN ARGUMENT!

Serriously, stop doing «cat | grep»

Re: Post your handy self made command line utilities

Another AUR helper... in Python!

I build my packages in ~/aur by hand. I'm not a trusting person, so I like to look through every PKGBUILD before building. I don't know how you guys can use that yogurt thing.

The library--including a PKGBUILD class:

#! /usr/bin/env python
#
# Desmond Cox
# Jan 21, 2008
#
# aur.py: helpful classes and functions for working with the Arch Linux 
# User/Community Repository (AUR)

### Imports

import os, urllib, urlparse

### Constants 

AUR = 'http://aur.archlinux.org'
HOME = os.path.expanduser('~')
TEMP = os.path.join(HOME, 'upaur.tmp')
DEST = os.path.join(HOME, 'aur')
FETCH = '/usr/bin/wget -N -P %(dest)s %(source)s'

### Exceptions

class aurError(Exception):
    pass

### Classes

class PKGBUILD(dict):
    def __init__(self, pkg):
        dict.__init__(self)

        self.vars = ('pkgname', 'pkgver', 'pkgrel', 'pkgdesc', 'url', 'license', 'arch', 'depends', 'optdepends', 'makedepends', 'conflicts', 'provides', 'options')
        self.url = urlparse.urljoin(AUR, 'packages/%(pkg)s/%(pkg)s/PKGBUILD'     % {'pkg': pkg})
        self.tgz = urlparse.urljoin(AUR, 'packages/%(pkg)s/%(pkg)s.tar.gz'     % {'pkg': pkg})

        urllib.urlretrieve(self.url, TEMP)

        try:
            f = open(TEMP, 'r')
            data = f.read()
            f.close()
        finally:
            os.remove(TEMP)

        for line in data.split('\n'):
            x = line.strip()
            for var in self.vars:
                if x.startswith(var):
                    val = x.split('=', 1)[1].strip()
                    val = val.strip("'")
                    val = val.strip('"')
                    self[var] = val

    def get_tarball(self):
        os.system(FETCH % {'dest': DEST, 'source': self.tgz})

The program--upaur (think uproar):

#! /usr/bin/env python
#
# Desmond Cox
# Jan 21, 2008
#
# upaur.py: check the Arch Linux User/Community Repository (AUR) for updates to
# foreign packages

### Imports

from subprocess import *
import aur, os, urlparse

### Constants 

PACKAGES = Popen(['pacman', '-Qm'], stdout=PIPE).communicate()[0].split('\n')
FORMAT = " %(pkg)-30s -- %(status)s"
HOME = os.path.expanduser('~')

### Exceptions

class upaurError(Exception):
    pass

### Main

if __name__ == '__main__':
    print ":: Updating foreign packages..."

    for line in PACKAGES:
        if not line:
            continue

        pkg, local_ver = line.split()
        pkgbuild = aur.PKGBUILD(pkg)
        remote_ver = '%(pkgver)s-%(pkgrel)s' % pkgbuild
    
        if remote_ver == local_ver:
            status = 'CURRENT'
        else:
            status = 'OUTDATED'
    
        print FORMAT % {'pkg': pkg, 'status': status}

        if status == 'OUTDATED':
            update = raw_input(":: Retrieve tarball? [Y/n] ")
            if update in 'Yy':
                print
                pkgbuild.get_tarball()

Enjoy!
